[@TheReverendSlim]

I'm going to try to calmly go through this by the numbers. If anyone ever reads this, I'll be surprised... but let's do this. 1. In-ceiling or ON-ceiling (or even on-wall) is irrelevant. The only issue with in-ceilings is with the ones that point straight down. At the Dolby spec'd 45 and 135 angles, most in-ceilings that aim straight down will have such poor off-axis response that it isn't ideal. BUT many in-ceilings now have either angled baffles so they point toward the MLP (making them functionally the same as a speaker mounted ON the ceiling) or at least aimable tweeters so you get the directional part of the sound aimed toward the seats. Those most directional frequencies are what matters most for cross-channel imaging. 2, The physical speaker boundary in the home is NOT supposed to line up with the orthogonal mixing interface, but with where speakers would be in a much taller space like a movie theater. What matters is THE ANGLES. We hear in terms of azimuth above us, so what is important is our ability to hear amplitude-based steering in certain regions of the room. The interface is an abstraction layer to make it easier to visualize general placement in a room. Now, in theatrical processors, the data gets adapted to the space by way of the initial setup making you input the room dimensions and the locations of every individual speaker in that room. If the home version relied on that, it would have been a bit outside of what your "average user" would understand (though us enthusiasts would love it - and Trinnovs implement some of this). 3. Research shows that we have a pretty good ability to hear between speakers on the vertical up until just over 45 degrees. Where imaging between two speakers falls off is as you hit about 60 degrees of separation (whereas 60 degrees of separation in front of us for stereo is great), at which point people surveyed were unable to accurately place sounds steered to the upper speaker consistently. The reason this is important is this: Yes, when you place speakers at your room boundaries closer to the 30 degrees of the front/rear height designation, you are making that interface match your speaker boundary in your smaller room. You're ALSO leaving a 120 degree angular gap. Contrary to what you say in the video, this actually makes it WAY harder for sounds to image above the listener. In a top front/rear configuration, you would only have about 90 degrees of separation above the listener... which inherently works better for placement above the listener. Static placements won't be precise, but they don't need to be... because research also shows that our perception of spatial resolution above us isn't that great. However, our ability to perceive pans across these speaker locations tends to work pretty well regardless. 4. The areas of the room that you show with a red X do not get "no coverage". Because we hear in terms of azimuth, those regions of the room get imaging between the two layers for sounds NOT at max Z in the interface. So for example, if an object in front of you directly between two adjacent speakers on the vertical was at say 0.75 on the Z axis, this means roughly that 75% of that sound will be in the corresponding height... but that 25% would be in the ear-level channel. So with two speakers with 45 degrees of angular separation, you would hear that sound at about 33 degrees... or basically where your front room boundary is (or where that green circle is at 5:50ish in the video). In the case of your Atmos file, as your voice moves upward, it cleanly pans from my left main to my top front left speaker. Now, does the sound appear to be closer to me once it stops at max Z? Yes, because... 5. Precedence. The fundamental truth is that a speaker closer to the listener will inherently sound closer to the listener. This is why in a perfect world, we would have a layout where the distance from us to every speaker is exactly identical. But none of us live in that perfect world, which is why our AVRs have distance/delay settings. This makes it so that sounds from speakers at varying distances will all arrive at the MLP at the same time. So as sounds move from speaker to speaker, these delays ensure that those pans move to the right degree for the intended placement. They also help lock imaging between speakers. BUT although this works great as sounds move between speakers, when a sound is firmly planted in a speaker that is physically closer to the listener, your brain still goes "That's coming from that speaker there." whereas sounds imaged between multiple speakers tend to kinda' image THROUGH their physical plane more generally. 6. The quality of your AVR/Pre-pro will not affect where you perceive a sound to be with top front/rear nor will the quality of its room correction. That speaker's imaging BETWEEN speakers will be affected by equalization (because you actually need those high directional frequencies to image well between speakers), but a sound from an individual speaker will sound like it is coming from the direction of that speaker. Now what CAN affect this is something like Trinnov's re-mapping, which can alter how all of this stuff gets steered... but that is a whole other conversation. 7. At 7 minutes, you ask how in-ceiling speakers will image a sound right above your head. Actually, they will image a sound there FAR BETTER than front/rear heights will. Why? Because they're phantom imaging between 4 speakers with 90 degrees of angular separation. Speakers at 45 degrees of elevation, too, which will already inherently sound more "above" the listener than those at 30. If they're pointed down, you still get the imaging there... IF you've equalized to account for their off-axis response. With angled in-ceilings, it would be no different than if you had speakers mounted on the ceiling (like my Prime Elevations), because the directional frequencies are aimed toward the seats. It can't "image it a little bit lower" or higher because at that point, it is just imaging IN TERMS OF AZIMUTH. You are hearing that direction, not a coherent point source. What COULD image it a little bit lower is if the object was brought down from max Z and the side surrounds started to get some bleed of the sound... but that kind of in-room placement doesn't resolve as well. 8. At 7:34, you say that if you have front/rear height, they will "for sure be able to image that sound without issue." This is exactly the opposite of how imaging works between speakers. You will never get better phantom imaging between two speakers with equal amplitude at 120 degrees of separation than you would at 90 (and the lower the angular separation gets, the more coherent the imaging between them, up to a point). This problem is exactly why Auro in the theater uses a VOG speaker - because that's where the inherent weakness is in imaging in their layout (though VOG in the home doesn't work quite as well, because... see Precedence). You are effectively trading imaging overhead for more compressed imaging from ear to height. Front/rear height objectively, absolutely makes it MORE difficult to image sounds precisely above the listener. How much does that matter? It depends... because remember, that region of hearing around us is where we lack spatial resolution anyway. 9. You're not missing anything with a top front/rear placement. Because of the separation angles and how our hearing works with elevation (which I had a long fun discussion with Joe about recently that I won't rehash here because it was nerd-level talk about AES papers), you're actually gaining precision - not just in the region directly above the listener, but in the areas about half-way between your ear-level and height speakers. To summarize what we discussed, front/rear height gets you about 15 degrees of precision for elevation above ear level, whereas top front/rear (whether in or on-ceiling) gets you about 23, with the regions below that being spatially imprecise with steering anyway. That part is, in my opinion, MORE important for good Atmos than just the "directly above the listener" content. And I say that having done every possible layout one can do for 7.1.4, upfirers included. 10. So what does all this mean? It means that the disconnect you speak of isn't that the orthogonal interface doesn't match up with the boundaries of a smaller home space, because it isn't supposed to. The disconnect is that the Atmos mixing interface is, at a foundational level, just a perceptual room-based interface for what is ultimately still vector-based amplitude panning with an additional aspect that attempts in-room placement. And once you wrap your head around it, you'll understand that what is most important is maintaining angular separation between speakers in each region of the room such that amplitude panning is still stable between each adjacent speaker. It's why Dolby's mix room guidelines are for 7.1.4 with top front/rear placement. That is literally the minimum layout being used for all home mixes. Everything above that is to add precision in larger spaces or coverage for more listeners. Thank you for attending my TED talk. If you made it this far, comment "Channa's shirt is dope." 😃

Channa’s shirt is dope!

[@joentell]

Maybe you and Home Theater Guru's can be on with Channa and me because you both seem to mostly agree. And I also think I understand the concept of the angular separation. Perhaps we can make this a long-form discussion. We could set something like that up. It would be interested, and I'm open to learning and sharing my findings. I think we can come to a better understanding that way. Somehow, I think we're saying very similar things, but in different ways. I also think that we prioritize different aspects of the sound with regard to precision and panning. In audio, we are always working with compromise. Do you want better panning of sounds overhead, or do you want more cohesion with the ear-level speakers? That's a compromise. We have to be specific about how different layouts improve the sound in one way, while degrading the experience in another way.

[@marcoscova8271]

Chana's shirt is dope!

[@easyrider2020]

Channa's shirt is dope! I agree wholeheartedly with Atmos 7.1.4 speaker placement being based on azimuth angles between all of the 11 speakers to give a more precise placement of a sound object anywhere in the 3D room. Visualize a smooth pan from front height to rear height - if the angle between the front height and rear height speakers is too great, the pan between them will "jump" front to back as opposed to a gradiant transition as the pan was mixed. I think using a protractor and measuring tape is the best way to place your speakers as the Dolby Atmos spec was engineered for on a good mix, and the front/rear height settings on AVRs is only for those who won't or can't put holes in their ceilings and are willing to settle for a compromise, like using Atmos sound bars or up-firing Atmos enabled speakers. As always, your mileage may vary.

[@danielgarvey8255]

Thanks so much for this video! Just last week I purchased a Denon 6700h, with intentions of Atmos. I have 7.1 bed layer of def techs and wanted the Atmos experience. Everyone said ceiling or upward firing. I had 4 extra pro monitor 1000's, so I decided to follow the Auro 3d set up. Two above my mains, and two above my back surrounds. All I can say is wow! My front stage sounds like I have towers.I have Demand d11's as my mains and 4 d9's as surrounds, the 1000's compliment them perfectly. When best buy installer came, he said that this was wrong, but he did it as I requested. After we calibrated, he was amazed, he said that he had no idea, but was impressed. He had no idea about Auro 3d. Thank you again for helping me make this right decision.

Wow, it's so incredibly true!! Immediately I changed the 4 top speakers from ceiling to actual height speakers and the object placement is so much clearer. The Auro3D tractor demo now is amazing, really amazing (i do have a VOG which is almost mandatory now that the front heights are further away from the listening position) Thanks for the insight Mister de Silva.

[@thelawfamilyproduction329]

OMG, you are finally proving that I am not crazy! In the beginning, I did a 7.1.4 set up for my Auro 3D with the 4 height speakers. The home theater sounded really 3D like with airplane sound coming from the front top, all the way to the back of the room. Then I upgraded the system, made it to basically a overhead placement, and it sounded restricted. Just sudden height sounds but disappears. I have been telling people to set it up with height speakers, and they all think I am crazy.

[@TechnoDad]

Yup!! Funny thing…all these other Home Theater KZbinrs say I’m wrong, but I’m not. And since I’ve been making Atmos for the past couple of years, I can tell exactly what’s going on.

@TechnoDad yea... blinded by the truth. I have two atmos systems at home, and height speakers is 100% the way to go. Keep up the good work. Subscribed.

[@alclowe1481]

Hello, Techno Dad. Dolby Lab at the time, was too busy competing with DTSX, but failed on understanding thier atmos platform itself. When, creating atmos, it requires from users to calibrate thier listening room into a 3 dimensional 180° half sphere. Which means the thier height speakers are in thier correct placements, however our room isn't a half sphere, its either square or rectangular shape. So it completely throws out thier dolby concept. What users needs to do is to install front and rear heights speakers instead. We're got two layers of speakers working together, e.g. bed levels and F/R height levels. You'll have better imagining and steering sounds that way. For example, in the movie Back to the Future, in the scene, when the clock tower gets struck by lightning. The front height channels engages in that track, they gives the presence of elevation!! The sound resonates rearward towards rear heights, completing the heights channels sequence. Dolby Atmos, is a object based surround sound experience, but the way they're suggesting the in- ceiling speaker's placement is down right wrong.

[@bigmike4133]

Just to be clear does that mean we should face the height speakers straight out or should we still angle them down towards the listening position?

Running a 5.2.6 setup with an Anthem 1140. - Top middle is designated “middle in-ceiling” and an actual in ceiling speaker - Top Front is designated “Front on wall” and is a ceiling mounted speaker angled towards the row of seats (but not toed-in to MLP). These speakers are located 45 degrees - halfway between seating and front wall. - Top back are designated “Back on wall”. These speakers are angle mounted towards seating and are at the ceiling/wall junction - Theatre Area is small - 12’ from front to back and 7.5’ ceiling - Seating is 2’ from wall. I loved your test video(s) and are great system tests. Results: 1. When you played the middle content, only my middle were is use. So if both backs/fronts are supposed to be in use in a .4 system, and middle only in a .6 … its working. 2. Panning around the room, bed layer, and height layer was as per expected. 3. Room size perception and separation of bed/height layers. Even though my front heights are halfway, they don’t make the height layer seem small. They actually do the opposite and open up the top. At their location they provide very good separation between bed/height due to my lower ceiling height. If they were further to the front that separation would be eroded. So while not ideal for going straight up from bed to height (your left speaker example) as mine does move in. The setup is much better for overhead effects and panning - helicopters, rain …etc., which is a higher priority for me. Hope that helps

[@theNABILcompany]

Thanks for this project. After watching a bunch of your videos, and a bunch from your peers, I got the confidence to overcome the limitation my concrete ceiling produced and went for 2 heights on wall up front, above my FL and FR, about 3 inches below the ceiling and 2 in the rear, at the same height, about 4 feet behind my SL and SR. I played around with a lot of official Atmos demo content and found it cool but nothing placed the sound exactly as intended like your video did. Until your full video, I was concerned about not being able to image sound above my head but when you move it across the top and to the middle, I swear it sounded exactly like a speaker had moved across my ceiling right to the top of my head. I have a 5.2.4 setup now. An Anthem MRX 1120 running PSB Image T6 x2 , XC, XB x2 with a level matched Paradigm Cinema Sub and SVS PB1000 with 4 SVS Prime Elevations up top. I'm wondering if I would have even more benefit from throwing 2 more up top, 45 degrees ahead of me (contractor buddy pitched a tray ceiling attached to my concrete ceiling idea and I'm considering it). Considering how I could trace your sound almost perfectly with my eyes closed as it moves around and above me, in my space, 16x16', I wonder if it'll add anything worthwhile or not but then again, it shouldn't diminish what I already have, right? Thanks for your great content, friend.

[@mohannair]

Ok just tested this on my system. I'm running 5.2.4 with 4 in ceilings as per Dolby. Yes when the sound goes from front left to top front left it does go right up but slightly towards you - however it is still distinctly above and far forward. At the end of that transition from FL to FTL, the sound came entirely out of the top front left speaker. So it doesn't feel odd or that the sound is coming from somewhere it isn't supposed to. After running the whole video, my conclusion was that the point you are making is a valid one, BUT it doesn't really matter in terms of practical reality as the sound does come mostly from where you expect it to. I really enjoyed this demo and overall made me happy that my system works as intended - thank you for making one of the best Atmos demo files too btw.

Great video.

It was a comprise. Hindsight being what it is I think Auro should have just let them use it because it might have Studios more willing to do Auro3D mixes as well.

[@MrLookShiny]

I don't know where this rumor started, but it's simply not true. Auro-3D was originally developed as a music format, derived from experiments in surround music recording and playback that found that adding front and surround heights were greatly beneficial for that purpose. The format was later extended to cinemas. Atmos was developed for cinemas from the start, and as such never envisioned using surround heights, it only ever had top channels plus additional speakers in the surround arrays for object rendering. The home theatre implementation of Atmos simply followed this same paradigm, it had nothing to do with Auro licensing fees.

Ok well I am not the target you are looking for comments from (5.1.2 Upfiring, Denon) , but since I appreciate your hard work and this was a great test of my currently limited setup which I am actually investigating upgrading and seriously looking at front height vs ceiling speakers. With 2 Dolby upfiring any height info you sent front or back or middle it was all sent to the upfiring speaker. This really highlighted how bad upfiring speakers are as its so easy to locate the sound origin. What actually did an ok, slightly better job was when you were in height overhead, the matrix effect between the 2 dolby upfiring speakers took away most of the ability to locate the sound coming from the speaker and made it seem like it was somewhere overhead.

When you had the ball in the middle height, the sound came just from above like it should. And when you go front left to front left height it did go up and down. Again you did it my friend.

I calibrated the Denon with the Denon app. My wife and I ran the interactive video more than once and both of us agree that the sound appears where it is supposed to. The ceiling speakers point down and the tweeters are aimed at the center of the room. Our seating portion if very close to the center of the room. My room acoustics are far from perfect.

I’ve been into home theater since the 80’s and have dutifully upgraded each time there was a new format. I’ve tried to follow the Dolby specs as close as possible and have never really been very impressed with most movies (with a few exceptions, e.g., The Harry Potter series). Until you and your associates created some much needed clarity on speaker positioning and your interviews with Wilfred, I believed the reason there was so little envelopment with surround were poor mixes. While that’s still definitely an issue, you guys have convinced me that the Auro recommended speaker positions are sonically optimal for the way we actually hear and my upcoming dedicated room will be configured that way. Many thanks and keep up the great work!

Totally agree, I think in ceiling speakers is not the best way to go. Also, if you have in ceiling speakers you can't upmix to Neural:X or Auro-3D. You have to assign height speakers in speaker set-up or the upmix option is not available in Marantz receivers. I now have a 7.1.2 set-up with height speakers and get a tremendous front soundstage. Neural:X upmix from a DTS 5.1 track sounds great (BluRay The Hitman) Still missing the height 2 back speakers, but in time they will come.

When you put your voice in all channels the sound direction is expected. The matrix/imaging is decent too. I'm satisfied. Everything could always be better. Btw please put out more demos and with some good bass too ;. You could seriously make some money off a demo disc per say. Because of lack availability expense of theses things which you once pointed out in your bathrobe video 🤣

My playback was fine on a Shield, via Plex. My system in a Denon 3600H and I’m running 5.3.4. Seating is 30” from rear wall and 7’6” ceiling height. I recently moved my height channels from a FH/RH setup to a TF/TR setup. The FH/RH were just wall mounted shooting straight out and followed Dolby spec showing aligned with FL/FR. I saw some recently published videos from hometheatregurus channel suggesting different positions based on angles from Dolbys studio spec and aimed at the MLP. I feel like it’s a completely different and much better experience. My TF is 50 degrees and TR is 110 for a 60 degree separation between them viewed from the side. Viewed from the front they are 50 degrees overhead (45 degrees separation from surrounds) from the MLP plane. Technically the TM is the position for 110 degrees BUT your video with the plane flying overhead is 100% more convincing when that speaker is assigned to TR. It actually sounded like the plane came at, over and away. The TM did not provide that effect at all. When your voice moved from FL to TF it felt like it came closer to me. Makes sense, the speaker is much closer to me. The full TF/TR did matrix was centered but it felt closer to me then the center channel. The rear only effects sounded behind and above. Overall, at no point did the sound appear to come from the location in the rendering box. Just a thought though; the program displays the audio space as a square, but isn’t the point of Atmos to be a sphere of sound? I feel like the program should give you a sphere to design within and not a cube.

[@TheReverendSlim]

The interface is meant as an abstraction to represent a large room. We hear in terms of direction, so fundamentally, the point of all the immersive formats is to create a sphere of sound.

I have been arguing this point for about 2 years now, and always fail to get thru to anybody. Not only does it work for Atmos, but makes the setup more universal for DTS:X and Auro 3D. Now at some point a year or two ago I did see documentation that the heights are now approved for Atmos, but I am having trouble finding that documentation and only finding the old setup guides. I think the KEY here is not just slapping height speakers up, but ensure they are angled properly. I used a laser level for this and I clearly here separation for height speakers. The analogy I used to use was a helicopter. If a helicopter is in the distance, going straight up and then flying overhead that sound source needs to be able to go straight up in the air not be moving towards you as it rises like it would do with in ceiling speakers, the same way an object pans left to right is by fading it from left to right, that is exactly how an object moves from to back. So that object should not move forward towards you just by going "up" and the only way to do that sonically and correctly is having your height speakers in line with your front mains. then as it starts moving towards you it would start to fade to the rear heights. Full control of positioning both vertical and horizontal. If you pan left to right in line, it just makes sense to pan down to up in line as well. Problem is, while this is the RIGHT way to do it, its all about the Atmos mix, most mixes are just random sounds and effects and not true 3D audio. They may very well only mix in a sound effect that is an "overhead" effect, that works well with in-ceiling speakers rather than take advantage of what could be a really immersive 3D audio experience. The Atmos in ceiling setup is fundamentally broken and flawed, but nobody understands or agrees. But I am an Audio guy and I.T. Engineer I think differently, as I don't just listen to what is said, I think and learn. I have a Ambisonic 3D microphone setup and have done my own testing so that users without an Atmos setup can look around in VR to hear my setup and see how it works.

[@jamesbeshero2029]

Thanks for the demo! I’ve got a 5.2.4 system on a 3700h using Polk OWM3s configured as TF/R/L and TR/R/L. They’re mounted on the ceiling using gimbals and pointed at the MLP. Top fronts are just forward of and in-line with the front towers at 45° to MLP and top rear likewise behind the MLP in line with the surrounds. Positioning and panning matched the illustration and description in the video.

[@miroslav1845]

I thought that if the receiver doesn't support auro 3d, atmos speakers should be mounted in-ceiling.. I have the same receiver as you do, so I should actually mount 2 front height and 2 rear height instead of in-ceiling and get better dolby atmos experince? And in Denon configured as front and rear wall mounted speakers. Thanks!

Played the demo on my Series X. Playback was perfect and the location of your voice was spot on. However, my seating is similar to yours, so our theater seating is against the back wall. When the sound moved towards the back heights, in the middle, the sound seemed to be coming out of my projector which Is right above my head when seated in the middle. All other movement was exactly where it should have been. Great demo, and by the way, Panic Room sounds f**kin killer in our set up.

Only just found this video and i love this demo. It works very well for my up-firing Dolby speakers. But top centre to top centre back is a problem because my Dolby speakers are surround heights, not surround back heights. So the pan from above me to behind me doesn't work as well as it should. I did a test rewire and speaker substitution and your demo now works perfectly. So now I have to properly move my surround heights to the back and buy some more speaker wire. When they say ignorance is bliss I'm not sure about that. But it sure is less hassle and expense :)

Awesome video. Thank you. I having been looking for a test video like this for a while in order to test out my system. Was able to test on my system via Plex using Roku. Speaker setup is 5.1.4 with in ceiling speakers being front heights and centers. Rear channels are mounted on the back wall. Setup is the way it is, because I have grown the setup organically over time. AVR is Onkyo TX-NR 7100 with Dirac Live calibration. My testing with your video found that the sound in my room is being matrixed very well based on where it is being placed on the onscreen renderer. This is even with the front speakers being mounted in the ceiling and the rears on the wall. The front staging with the up and down testing was accurate. I think this is because I have the front ceiling mounted speaker mounted right above the fronts. I believe that the accuracy in matrixing of my high channels, which as mentioned in my case are quite different, is because of the Dirac Live calibration. Thank you again for making this video. I finally now understand what my system is cable of and its current performance.

My personal opinion... My set up 12.2.6 all format theatre Setup. Auro-3d Atmos DTSX. I have 4 heighted speakers and 6 in ceiling speakers...

[@bronstet]

When I added Atmos to my setup, I experimented with both in-ceiling and height positioning. The biggest problems I found with in-ceiling positioning is that 1. The sound is directed down vertically and clashes with the horizontal bed layer causing a weird reverb; and 2. Our ears are not as well designed to pick up sounds above and away from us and I was not actually picking up the full sound from the speakers. When used in height positions on the walls and angled correctly, I found the sound directed more naturally to my ears and I could pick up both the height and moving object cues much better. I actually followed SVS's advice and mounted them on the side walls, not the front and back. I found that if they are mounted above the front and back speakers, they extend the front and back soundstage vertically but you cannot differentiate the height and object placement anymore. As someone posted below, it's like suddenly having giant tower speakers. Don't get me wrong, that can be pretty fun too, but it hasn't really spread out the soundstage any more. When placed on the side walls, the soundstage now becomes a full bubble and I find the cues are differentiated enough. So yes, it's more like an Auro-3D style placement I use with height speakers. Very happy with my setup and I recommend it be tried once. You can always rearrange if it's not to your taste afterwards.

[@Adonis-qj1nq]

Thanks so much for this video @Techno Dad. I wasn't sure if my Atmos setup was working properly (I just purchased all the equipment over the holidays), and this was a much easier test to use than trying to find good Atmos movie scenes and then trying to mute all but the Atmos speakers. So my equipment: I am using a Denon AVR-X3800h. I have Kef Q Series speakers in a 5.1.4 configuration. My Atmos speakers are the Q50a upfiring speakers. I know you mentioned you wanted to test specially heights and in-ceiling, but you might find my results interesting. I have the Atmos speakers setup in the Dolby upfiring mode (I might set them up with brackets as heights to see if my results and effects improve, or I might leave well enough alone, I haven't fully decided yet). Results: I heard all the sounds exactly where they should be, except for the top right corner of the room. There I had an issue where it sounded more like it was from almost the same position as the rear surround. I'll have to make sure I am setup according to the proper Dolby distances and re-calibrate the system to retest since it is odd all the other locations worked flawlessly. I guess upfiring speakers can work!😁

For the time being another pair of bookshelf speakers are sitting on top of my front L+R and another pair on top of stacked subs either side of the TV. I will be getting stands made for those two pairs of bookshelf before christmas. Arriving next week is a matching [single] bookshelf speaker to be used as a "voice of God" and I am getting a stand made for that speaker as well. I am now considering another pair of front main speakers to sit on top of my current main L+R, they will be matching of course. Once it's all done I must send you a photo or two. Fingers crossed it will be all setup before christmas. Hope that all makes sense.

[@scottlatusek2527]

So mine is 5.1.2 with Denon S710w, in ceiling at ~80deg per Dolby guide with tweeters pointed down; not your target audience but thought I'd also comment. Your voice mixes well from L to R, but front to back is where it gets messy. As you correctly state, when moving vertically, sound moves up and toward the listener. Since my overhead is only a couple feet in front of the listening position, it basically sounds overhead (that's bad). When moving front to back in the overhead plane there is no change because I only have 1 set of overheads, so I can't comment. It was definitively and interesting test. I'm definitely going to see how this sounds on my parents 7.1.4 setup and see if I can temporarily move the overheads closer to an auro-3d layout and see if we like the results better.

[@joentell]

I'm curious to hear the results of your testing

[@TechnoDad]

Thank you, Scott! Let us know what happens on your parents setup.

[@scottlatusek2527]

@@TechnoDad So I finally made it home for Thanksgiving to play on my parents setup. So they have a 5.0.4 system (using front towers for subs ... works for them). Overheads are in ceiling, in a typical arrangement with front and rear in ceiling probably closer to the 55 and 125 deg angles per Dolby setup guide. AVR is Pioneer LSX-LX303. Playing the video it does a much better job than my setup since it has a couple of extra ceiling channels. However, it still does not correctly move the sound up the wall. So we removed the front left ceiling speaker and mounted it on the wall as a front height channel. Immediately we could tell that the sound moves vertically vs up and toward the listening position. So we did both. So now we have set the AVR to front heights and rear in ceiling. I like the result, but it needs another set of overheads as a top middle. What I've found is that when matrixing the overhead right above your head, its not as impactful. It does correctly fire all 4 speakers (or 2 if on the left or right), but you can't quite pinpoint as well and the volume drops a little. I have a helicopter atmos demo (I think I got from dolby website), and as it flies from my front height channels to my rear in ceiling, there is a very noticeable dip in SPL when between the two speakers. Maybe a better processor could fix that; I'm certain having 6 overheads would. I did run the Pioneer auto EQ, and verified the output with a phone SPL meter (not the best but I didn't bring my microphone from home). So each speaker does play the same level when doing the manual test tones. I don't have the ability to do a room sweep and see if its a room correction issue, so it could be that. I think the 4 overheads really needs to be set up as front heights. We don't have the ability to drill a new hole in the ceiling and test a front in ceiling solution, but my concern is that unless the in ceiling is angled at the listening position, it will sound weird since half of the speaker output will hit the wall and reflect. I'm not sure angled tweeters would do it. Based on my testing this week, I actually will go with 6 overheads in my room when I eventually upgrade. Front and rear height channels and then an in-ceiling as top middle. Thanks for figuring this out.

[@aniketnraut]

I played the demo on my 5.1.2 system Denon X4500H .2 are front height speakers. Front height were quiet spot on in their presentation, Up Down was perfect only when it went to back height it sounded like sound was matrixed from rear and front height or may be just rear speakers. Even the Top center sounded like it came from front height.. other wise the demo was superb and truly was able to experience Atmos mix. One more observation i want to point out here. Denon is capable of Auro3D when i switched the sound process from Atmos to Auro3D all the height channel output was actually played through the front channels and none from the height speakers. which was quiet a surrprise. Ideally Auro3D should be able to utilise the height channel and play it well.. but well it just didnt!.

[@baronbob6971]

Auro cant access the height information encoded in Atmos. For me also everything was playing on the floor. But in the corners there was a strong reverb with Auro. I tested with some Movies like Blade-runner or edge of tomorrow how good Auro can reproduce height information by up-mixing. And with movies the algorithm is astonishingly good. Perhaps it just did not got the information needed to place TD in the heights. I always use Auro3D on Atmos tracks. Not because Atmos is bad by itself but because the production of Atmos tracks in Hollywood is FUBAR. But this is another topic. End of line for me is, even if, and this is a big if, Auro has sometimes less quality in the heights than Atmos, it still makes the whole movie sound better. And I take a whole movie anytime over 5 seconds or less in two hours.

I just set my 5.1.2 with top middle atmos, and I only hear some specific sound, like airplanes on top, but for example, in Matrix, when neo are using the glattling gun to save Morpheus, the sound comes from the front tower speakers and not the top atmos

[@CorporateZombi]

I'm not sure how you think Atmos works. But Imagine stereo. How is that done? It's done with balance between volume and delay between your left and right speakers. I presume that is also how the in ceiling speakers will image a height channel; by balance and delay between your all your ceiling and ear level speakers. This is done by the calibration of your space by your avr. Your speaker boundary argument doesn't make any sense to me, because the sound from any speaker bounces all over the room anyway. The calibration sorts it out to get the object based sound to your ear at the right times to fool you into thinking that is where the sound came from. That's why you only get the best listening experience at the exact position where you place that calibration microphone. That is how Atmos can be used with multiple different combinations and numbers of speakers and room layouts. Up firing speakers that bounce sound off the ceiling must by virtue of the distance sound travels and spreads before reaching your ear must be more diffuse in their position characteristic. Sound that comes directly from the ceiling must be tighter because it has traveled less far. Either way the processing has to sort it out to balance the audio sources to give the illusion of a 3d volume sound-scape. Obviously the more speakers you have, the more detailed the sound position can be, because there will be less smearing of the sound necessary between different speakers.

[@joentell]

I probably sound a bit rude for saying this, but have you tried different height speaker placements i.e. on-wall vs in-ceiling? I'm just asking if you're speaking based on experience or mainly theory. From experience, I can say that calibration cannot "place" the speaker anywhere you want. We can localize the sounds regardless of what the calibration does. The physical location of a speaker still has a large effect on the sound we perceive. Some of those things cannot be changed using DSP. The idea that Atmos allows the mixer to realistically place an object anywhere in space is also a pipe dream. It can place sounds where there's a speaker. It can do that very well. It can image a sound midway between two speakers, but that isn't nearly as precise. Any other locations are even less precise.

[@welderfixer]

@@joentell Sir, you are very much correct. There is no f'ng way that a processor at any price can make up for speakers placed in the wrong positions. Period - impossible! The machine setting distance and volume - yes, placement NO. The only way that ANY of us can get perfect speaker placement and imaging is to 100% copy the speaker placement of the mixing studio that engineered the sound track - also PERIOD. Until we ALL have our speakers in the same positions as the studios we will never get the true playback experience. But, that will never happen because we will never know the studio set-up and, of course, every studio is different. Dolby and their lack of wisdom and common sense has never made speaker placement "set in stone". I know you know this very well, you have been at this game a long time and you are one of my HT gurus. Thanks Joe and all the very best to and yours, Kevin G.

[@CorporateZombi]

@@welderfixer I thought the whole point of object based sound was to solve this issue. The sound is supposed to be positioned in space. The avr processor then interprets how to produce that based on the speaker arrangement you have selected, be that 5.1; 7.1; 5.1.2; 5.1.4 or 7.1.4 or whatever. Obviously you have to put the speakers in the right place relative to your listening position. I.e. up firing height speakers on top of your front left/right & rear left/right speakers etc. Angles of speakers as per diagrams on on-screen displays etc. Then calibrated for volume and distances etc. And maybe even room acoustics. Is the argument here that avr's are not working like this? Or that Dolby Atmos soundtracks are not working like this? Help me I'm confused! What I do know is that surround feels 'planar' in terms of sound stage compared to Atmos sound tracks. Whether you could pinpoint a sound position with your eyes closed is another question entirely, and probably beyond the ability of only 4 height channels with sound bouncing off a ceiling to produce. Most Atmos receivers don't even standalone support for 4 height channels, and now you have soundbars that claim they can "dolby Atmos". Heck even my phone says it can "Dolby Atmos" and it's weirdly convincing! So how do they work? They must use significant processing! But with known speaker locations.

[@welderfixer]

@@CorporateZombi The "Object Based" system gives the audio engineer the freedom to place the audio from - lets say - a bird flying around the camera accurately within the sound track. The engineer will have to move that "object" thru the speakers based on his/her own thoughts of where it should be and place it within the speaker locations in their studio. If our speakers are not in the same location as the studio and our AVR distance and volume level settings are not correct, the audio playback to our ears will never be as intended. In my opinion, the only way for each of us to tell if our speaker placement is "close" to correct is to carefully watch several films/demos and follow the audio object with the motion of the visual object on the screen. Examples: Does the helicopter fly overhead from front to back, does the car drive by from left to right and then to the right rear with correct timing and so on. If there is a big "hole" or a "compression" in that audio/object motion then something within the system is incorrect. This, of course, means we have to use a top quality film clip or demo material. Our friend "TechnoDad" is doing his best to give us such material, because there is so few correct and quality "calibrated" Atmos demos out there. There should be and maybe there is demos that are mastered in each speaker configuration in use, but I have yet to find any. Any of those disks are horded and kept "Top Secret" by those that have them. With all of the failings of Dolby, the studios and the equipment manufacturers on telling us where "exactly" to place our speakers the machine cannot tell where we mounted our speakers. Maybe someday with a billion dollars worth of software R&D the machine may be able to figure out where we placed our speakers. One would think that some of the Billionaire priced machines this feature would be available today. I hope this helps. Please ask any questions, I'll try to help as most of us in the "hobby" would. There's a lot of long time experienced guys and gals willing to help. All the very best to you and yours, Kevin

What is very noticeable is that when I turn on the 4 upper speakers from Height to Top in the settings menu of my Yamaha RX A 2070, the voice sounds like a kind of reverb when it is centered above my head, i.e. when all 4 upper speakers are controlled simultaneously. This makes it sound diffuse from higher up. If I set this back to Height, the diffuse reverberation is gone. Somehow the Atmos algorithm in the top setting works in a way that alienates the signal, perhaps to close the gap in the distance between the floor and ceiling speakers via the diffuse reproduction

[@shonholland9111]

I'm using on wall for my Atmos and for the most part all the panning was correct using an AVM 90. I did notice an issue when the placement was in the middle of the front and rear heights. The sound was more prominent towards the front instead of being in the middle. I was able to correct the imaging by raising the trim of the rear speaker by about 4dB. My front and rear speakers are a different brands and I've always wondered if that would make much of a difference for Atmos content and this kind of proves that it does.

I actually use height channels because I have a smaller room and agree it sounds more atmospheric that way compared to a buddy using 4 in ceiling speakers. So glad you agree as well.

Currently have Atmos 5.2.4 Configuration with wall mounted Height rather than in ceiling. Front Heights mounted on wall near ceiling, not quite (but almost) directly above L/R Mains. Rear Heights are side wall mounted (near ceiling), close to where top corners where side and back walls meet. Height locations are limitations imposed by the Living Room layout (and wife acceptance factor). My Denon Receiver with Audyssey xt32 appears have done a pretty decent job with the room calibration. When running your Atmos demo: The location movement from L/R Front to Front L/R Heights and to the "Above" Central Height location was all handled fairly well. Even my wife (who is not into these things, and just "puts up with it") was able to notice it. My Atmos Height setup is currently a Frankenstein's Monster of mixed speaker brands. Front and Rear Height Speakers are from different manufactures, so heights are not timber matched. I normally dont notice the timber differences with regular ATMOS effects/content. However, this demo consists of your "voice" moving. The timber differences were OBVIOUS when a voice was moving from Front Height to Rear Height locations.

This is a super interesting experiment. Thank you for putting this test video together. I'm now questioning the positioning of my Elevations, but will leave them as is for now because I don't want to put more holes in my drywall :)

[@TheReverendSlim]

Yeah, you put your heights too close to you. I also run Prime Elevations on the ceiling, and the baffle angle only being 20 degrees comes with some compromises because putting them too far forward/back will get you outside of their usable listening window. But you should be able to move them to 45/135 (if you're physically able to) and get better pans from ear-level upward... and better longitudinal movement with pans. Where I screwed up with mine was mounting them pointed straight forward/back. Looking at the dispersion pattern of the Primes in general, it would have made more sense in hindsight to rotate the mount 45 degrees so they aimed toward the middle of the room, which would have given better seat-to-seat coverage for people sitting to my sides. It still sounds great how I have them... but you do see a dip in response near where SVS crosses the tweeter over to the mid. And someone sitting on the left doesn't hear the right heights as well, and vice-versa. I say move them. Holes in drywall are easy to fill. And I know... This isn't where my Elevations were when I first installed them. 😉

[@texmuphy68]

More, more, more please. Keep 'em coming! This was a much needed video, as many existing test videos only use a test tone or noise and don't pan from speaker to speaker. It was also helpful that there was a piece where your voice was rear centre for some time, which made me realise that my rear speakers weren't in phase, as I didn't hear you distinctly from the middle. In a next video, please do a left, right, both for each speaker pair. (front LR, surround LR, rear surround LR, top front LR, top rear LR) It's also very useful that your video is voice-based, so I could tonally optimise each individual speaker with the equaliser.

[@pchip6856]

Well done! I have been wondering about this myself for a while. I am running a Marantz SR7012 7.2.4 setuP. 4 height channel wide dispersion speakers firing straight down from 9ft ceiling between 45 and 50 degrees from MLP. Everything seemed to matrix well. At the extreme front to height transition, sound does move at a diagonal. However, when the transition is a third to half of the way between front and front height channel, it sounds like I believe it should. Maybe, it just depends on how aggressive the transitions are in the mix. It seems that each immersive sound mix file should contain qualifying data that could work with room correction software and apply appropriate transitional delays in real time too correct for different speaker layouts and rooms. Denon x3800h arriving today will give me a few more speaker layout options to try as well as more sub control. Also, allow me to try Dirac eventually. Cheers!

[@orcelfdeadhuman]

Thank you for creating what I consider the first ever Atmos configuration video! There isn't any material out there that help us test Dolby Atmos in our home theater systems. I run a 5.2.4 system with four Arendal 1961 height speakers. My height speakers are on the wall pointing toward the MLP. The height positions matches the 5.1.4 Dolby Atmos in ceiling specification, where the heights are not above the front lefts and rights. This video proved to me that setting the Marantz 7706 processor to configure my height speakers as Front and Rear Heights sound way better than having the processor configure them as In Ceiling. Your voice when the speakers are configured as in ceiling does not match the voice coming from the fronts. When they were configured as height speakers they matched. I also found out that limiting the Audyssey room correction to 300hz and below gives worse imaging for objects moving around than if Audyssey corrected for the full range. So now I let Audyssey correct for the whole sound range. When you speak from the front heights, the sound comes out from my front heights which are positioned closer to me which is what I expected. Again, thank you for the video!

[@TechnoDad]

Thank you! Glad you liked it. Something will be released on December 15th! Stay tuned!

[@xanderx9988]

Just finished listening to the demo. Here’s my setup. When i built the house, I had the builders install a 5.1 in ceiling setup (back when I didn’t know anything about proper speaker placement). 2yrs later i now have a 5.1.4 setup. I’m utilizing the 4 in ceiling speakers as atmos. Here’s the problem though. When watching movies with atmos mixes, the majority of the time, I can’t tell if the sound is coming from the L&R floor speakers or the L&R ceiling speakers. The same happened with the demo. I tried to create as much separation as I could get away with but it’s still not enough to make a big difference. Based on the demo, I could def hear the difference in where the sound was coming from all the locations which was really cool. The only time it was a little hard to distinguish the sound was when your voice was shifting from up and down between the L&R floor and L&R ceiling speakers. When moving from floor to ceiling, it basically sounds as if the volume was raised on the floor speaker. If I focus my hearing though, it does sound like it’s coming from the corner ceiling, but it’s very subtle. I have taken into account that some movies/shows just have bad mixes &/or just don’t utilize the height channels as much as we would like. Especially since the majority of the content that I watch is through streaming, which is not as good as physical media. I’m debating whether I need to raise the DB on my ceiling speakers or if I should invest in new ones like kef in ceiling speakers that have a 160 degree off axis dispersion. I would like to send a picture of my setup to further discuss what I’m dealing with if that’s possible? Plus, I appreciate you taking your time to helping us create & figure out the best possible experience for our homes.

Love the technical aspect of your vids with Atmos. One thing o did wonder and I haven’t had time to play with and recalibrate etc is does changing between Top vs Height on the AVR have much effect on sound placement, have you played with that much? (Personally I have TF and TR speakers in-ceiling)

[@terenceparrish6292]

Thank you, Terence! I guess they like to take the word of all the ‘so-called-experts’ over actual proof. Whatever…

[@reginaldloyola937]

Do you have your height speakers labeled as heights in the avr or as front and rear atmos? I have mine physically setup as heights but in the avr have them labeled as front and rear tops so the avr thinks they are in ceiling speakers. Should I switch them to heights in the avr?

[@markied2873]

This may be a super noob question but where would i run the wire from the rare speakers to the receiver? I dont want wires to show?

[@KevinStCroix]

Timely, was just about to build a truss overhead for four heights. I hadn’t heard about the lawsuit and always wondered how height channels can create a point source with that is discernible with such a wide gap between ear level and ceiling. Will have to try the heights on wall like the auto standard. I reckon that will produce a sound with a position that disperses the sound quite differently to the ears in terms of localization.

7.1.4 on a Denon x3700 and outlaw model 7000 amp. 4 bookshelf speakers mounted on ceiling within Dolby spec, angled toward MLP. I think the main thing with Dolby spec vs Auro or DTS:X is thinking of it more like a bubble shape than a rectangular box shape. My speaker placement is within the Dolby spec but being that they are bookshelf’s and not too far forward from the front L&R for example they are probably in between being ceiling and height. In regards to the demo, when going from FL to TFL it didn’t sound like it came really far forward. Just moved up to the TFL speaker. If I closed my eyes it seemed to love every so slightly forward but it was minimal. I noticed the biggest difference or limitation is our ears and where our head is facing. For example when you went from matrixing the TFL and TFR to the middle of the room directly overheard it sounded different but still sounded a little forward. However if I physically looked up at the ceiling it sounded directly overhead. Same with when you went to the matrix of TRL & TRR it felt like it was behind me but was also possible hearing some reflections from the front of the room. If I physically turned my head around so I was looking backwards that sounded exactly where it was supposed to be. I think people forget our ears are not a like 360 Omni directional mic and while we can hear everything around us, how clear we perceive it depends on where our head is in relation to the sound. I would really love to hear you and the guy at Home Theater Gurus discuss this. He has been saying we need to follow the theater spec for Atmos which actually puts the overhead channels closer towards to the middle of the room. He also mentions it’s good if you want to raise your rear surrounds and rear overhead channels by like a dB or 2 so your ears hear those sounds at the same volume you hear stuff in front or on the side of you. Our ears are cupped slightly which is not ideal for clearly hearing stuff behind us.

[@TheReverendSlim]

I've been preaching the theatrical and mix room logic for some time now, and though I don't agree with HTG on raising any of the speaker levels that way because of how it affects cross-channel imaging, he's correct about his methodology on placement and aiming. The shape of our ears does affect how we hear sound... but our brain adapts to how that works over time. For instance, the occlusion of your earlobe plays a part in how we perceive that a sound is behind us... but they've found that people who have had their earlobes cut off entirely gradually adapt (faster than you'd think) to their new ear shape and can still perceive sounds that are behind them. What differs more importantly based on where we're facing is our perception of spatial resolution. We can hear more precisely in front of us than behind or over us. But the way we lay speakers out largely takes that into account already.

Is the height of height speakers critical?? We sit 12 ft back from the main front speakers and I have 10 ft ceilings. Would I add the height speakers to the top of ceiling or "X" amount from the front tower speaker??? thx

[@Edward135i]

I doesn't mater if the speaker is in the celling or on the wall it's all about the angle from the seating position that the speaker is at. I set my ATMOS speakers up at a 55 degree angle 30 degrees apart from themselves and that made a huge difference in actually getting sounds above me, I'm using on wall speakers that are mounted to the celling with brackets angled at the listener. if anything you need a combination of speakers on the wall and above you like how DTS does their rings of sound. I tried the AURO 3D 30 degree angle with the VOG and I really did not like it their wasn't enough separation of the bed layer and heigh channels, i really couldn't hear the heigh channels with the speakers mounted like that.

[@timdmyterko4208]

I think I agree with what your saying William in regards to the angles. And as for the holes he's talking about doesn't make sense to me since the same could be said a about a person's bed layer if the speakers were spread too far apart from one another.

[@paulbb7533]

Late to the Party (as usual). I have pieced together a "system" comprising:- RX-A3060 (yamaha) as decoder only so just a pre-amp. Running a 7.4.4.1 config. 4 separately Eq'd subs and a sub pulled from the 4 height channels also to fill in for the small nature of the height speakers. This feeds through a Dolby CP-750 (bed layer EQ stage), and another 8-ch EQ stage (31bands/channel) for the 4 heights with 4 spare for future options. Then goes to power amp stage which at this stage is just a modified 7-channel yammy receiver to just amplify the beds and a 6-ch amp to do the heights. Very cheap amp options.. Currently building a 16 ch D-class amp for total domination of Atmos. This is all EQ'd manually (to the x-curce), which timbrally matches the speakers very well obviously. Using height (bookshelf) speakers in a non-traditional upper bed layer config (not aimed at listening position) it improves the height discernment but with them in the traditional X.X.4 positions they don't track the positions you mention in the accompanying video. I am considering moving the front heights to the screen wall to see if it makes a noticeable difference. It could be with the emission angles it may not be as noticeable as expected, athtough for the demo provided it would fit that brief. For feature movies, maybe not so much. Certainly an interesting idea, but since the decoding is specified as it is and the hardware should follow suit (in a cut-down consumer situation over the multi channel cinema experience which does have speakers at height near the screen) we will see.

Great & informative video. I got into ATMOS a few years ago with a Yamaha 5.2.2 RX860. I used 2 klipsch atmos wall mount speakers behind my 2 front towers. for atmos/ effects. I considered ceiling mount speakers, but, intuitively, I didnt think the imaging would work as well as wall mount, keeping in mind that I'd be upgrading to at least a 5.2.4 as the technology matured and prices became more affordable for me. I just had the DENON 3800 delivered the other day, along with 2 more wall mount Atmos speakers. Its going to get hooked up this weekend. Your videos have been incredibly helpful in how I will be laying it all out. Its a family living room, not a dedicated theater room, so it wont be optimal, compromises will be necessary, but between your tips, and the onboard DSP ( or is it sorcery?) I am confident its going to be amazing. Im really stoked about the 4 discreet subwoofer outputs and bass management. I use 3 subs and have issues with dead spots, in room resonance and bass bleeding into other parts of the house. The Denon 3800 should make a dramatic improvement over the Yammy 860.

I think I’m in this camp with the same question. 7’ ceilings and 20’ room depth, 14’ width and MLP at 11’ off front wall. F/R heights would leave ~140degrees of open ceiling. Assuming in-ceiling mids is the answer.

[@texmuphy68]

Setup: Marantz SR7010 7.2.4 speaker setup Atmos/top/height layer speakers: Bookshelf speakers, mounted according to Dolby specifications and aimed at MLP. I have used your Atmos Interactive video and found out that movement in the top layer didn't move front to mid and mid to rear as should/I would have expected to! (when set to TOP FRONT & TOP REAR as 'should') Turns out that the room boundaries in your software do not correspond with where I would need to hear what I see happening in your renderer. I have tested extensively, alternatively changed to every possible top front/front height/top middle/rear height/top rear settings of the amp-speaker combo. That gave me a great insight that is very useful for you. It comes down to the fact that the top/height layer is actually where the speakers are situated and (whatever setting) you never hear the front left/right (bed layer) going straight up to the top/height layer, not even when I put the configuration to front height and rear height! Best setttting where I hear your voice moving from top front center to top middle AND from top middle to top rear, is when I put the amp-speaker combo to FRONT HEIGHT & TOP REAR. (from which 'I' conclude, that with this setting I have virtually positioned the top layer, say about 2 metres, to the front/forward of me. (room is 7,50x3,00metres) What I also noticed, is that when your voice is supposed to be in the middle/centered of any of the top layer speakers, there is no real center image. (all speakers are in phase, I checked) It sounds more like a dual mono. It would be interesting if you could do a video where you try out some different object positions next. Hope my experience /explanation will help you/others. My quick notes listening to your ATMOS INTERACTIVE video: Setting of amp-speaker configuration : Front Height & Top Middle: Top Front to centre to above your head: GOOD Front Height & Top Rear : better. BEST for moving from top front to back AND middle to back (PREFERRED SETTING NOW!) Top Front or Front Height doesn't matter for going from bed layer to top layer. Never sounds direcrly above the front speakers where it should be. Conclusion: whatever you do in the front 1/4 of the room in your renderer, doesn't do a thing/not much. Top Front & rear height: front to middle: NOTHING. Middle to back: GOOD Top Middle & Rear Height : nothing front to middle. Middle to back: GOOD Top Front & Top Rear: front to middle: NOTHING (sounds already middle) . Middle to back: GOOD

It works very well. movement from earlevel to tops works great. and diagonal move also. My setup matrixes near perfectly to include matrixed sound from top middle. obviously, lack of ceiiling speakers means top-middle (overhead) is less pronounced than say, center (which is also at higher level) for me but top front and top rear are great and atmos also creates faux-top-middle of room effects quite a bit with my heigts. so i am happy with my setup. please keep on making these interesting videos. thanks for the hard work on these.. ps i have a pioneer vsx-lx303, 9 channel + sw avr in 5.1.4 layout. you video made me realise i had my level for rear-height left set too low so i set the db setting a bit higher in my avr channel setup. thanks for a great and instructive video.

The only thing is the Top Middle L/R on-ceiling speakers took over whenever the object moved towards the middle of the room. So the front & rear heights didn't put out any sound when the object was stationary in the top middle of the room because my layout has 6 height speakers. The sound was seamless when the object moved from the front of the ceiling to the rear. Front heights then transitioned seamlessly to the top middle, then smooth transition to rear heights.

If I had the money to make a 7.1.6 with 2 pairs of ceiling and 1 pair of front heights that would definitely be ideal. If you only have 4 channels for height than I think without question it’s better for overhead sound when compared to just 4 wall mounted height channels. Something that did make me torn was whether or not to have 1 forward height speaker & 1 pair of ceiling or go with 2 ceiling. I think so long as your ceiling speakers are properly placed it’ll work great. The forward front ceiling speakers are further enough away to simulate that height sound out in front of you..

[@slick1979uk1]

I sooner or later want to upgrade my processor. I am thinking about doing 2 pairs of heights and 1 pair of in ceiling mid room. For my fronts I currently have towers, but want to do wides also. With those I would do bookshelves.

[@TheReverendSlim]

The thing you have to be careful of with x.x.6 is that a lot of Atmos mixes use two static objects (the beds) at the top mid location and no dynamic objects outside of that. So say if you had front/rear height and top mid, those movies will play NOTHING from your front/rear heights and all height sound will come from the top mids. Ready Player One is one of those locked 7.1.2 bed mixes. With most of the content out there now, you'd actually be better off sticking to 4 heights at top front/rear, since those mixes with locked top mid objects will use all 4 speakers to image that sound between them.

[@anthonysmithjr.7388]

@@TheReverendSlim this is an under rated comment. are u saying most movies are using only 2 mid height channels. so it's best to stick with a 7.1.6 setup that has on a marantz/denon front heights, rear heights and 2 ceiling mids for the best results?

[@TheReverendSlim]

@@anthonysmithjr.7388 I don't know about "most" movies. It looks like increasingly, they're at least using dynamic objects during scenes that call for it and leaning on the height beds at top mid for everything else. And most Netflix stuff in Atmos actually uses dynamic objects well. And no, I don't subscribe to the theory that x.x.6 with front/rear heights and top mids give you the best results. The number of heights you use depends solely on how many seats you're trying to cover, and whether you use front/rear height or top front/rear depends solely on where those angular designations fall in your room and what your preferences are. For my money, the best results can be obtained with a 7.1.4 layout with well-placed top front/rear (whether in-ceiling or on-ceiling) because A) it matches the layout used to monitor home mixes, and B) it images static top mid objects in locked mixes between the top front/rear, which will give a more generalized sound than reproducing them from single point sources at top mid. There's a balance between coverage, aiming, and available resources.

[@anthonysmithjr.7388]

@@TheReverendSlim thanks for that very insightful comment. I have a marantz sr8015 in a 7.1.6 layout. I can't figure out if it's best to set the configuration to height front left/right, ceiling mid left/right and height back left/right OR... to set it 6 ceiling speakers left/right. I tested with the dolby app demo's and it seems to image and sound just the same either way you set it. Also for some reason if I set it all 6 as height the side left/right heights do not play sound as it seems that is not an ATMOS compatible configuration. Can only get atmos is the mids are ceiling or if the all the .6 speakers are set to ceiling (top). But i'd love to hear your insight on this. Also it doesn't seem to matter if i set it to ceiling but still keep the speakers angled towards me in a height position. it seems to image better that way anyway. Making me think dolby has the ceiling thing due to the Auro 3d lawsuit or whatever and that is the only reason they show their configurations this way. but i could be wrong, just a theory.

[@mezzup1]

I see what you are getting now lets flip this what if the atmos was mixed with in ceiling people in mind will it work well for those with front and rear heights

[@TechnoDad]

Well, as long as the sounds are moving around in the middle of the room, the in-ceiling speakers should work fine, it's when they get to their boundary and go passed it. 100% the mixing engineers are going to use all the space in the renderer that they can.

[@SamHocking]

The reality is the actual XYZ position of the height sounds in Atmos get set by metadata and for the height channels the object placement doesn't get set to ever be 100% height and 100% left in the corner, it's inset to something like 60%. When you mix music in Atmos and look at the levels of an object being panned to that 100% left, 100% right position, the level meter fro the top front left speaker doesn't keep getting louder past 60%. ie it's a greatly reduced soundfield as described in this video. So you could even argue, moving ceiling speakers will improve things by getting the sound to where it should be, but Atmos isn't sending the correct amplitude to that height speaker.

Home Atmos IS mixed with top front/rear in mind (whether in-ceiling or on-ceiling) and this is Dolby's preferred layout per their Home Studio Certification guide. It will still work well for front/rear height between the two layers, but imaging overhead will suffer just by nature of the speakers being wider apart.

I think you’re on to something. So I played your Atmos heights demo: Plex/Shield Pro connected to Denon X3700H in 7.2.4 (4 heights). My imaging results were about 90% accurate. It highlighted that my heights aren’t lined up with my L/R channels (they are slightly inside my bed layer) so the vertical up and down was slightly tilted, but technically accurate. As a result, I’m planning to align my heights and recalibrate. It would also be nice if you did a similar demo but using a sound or tone instead of your voice, as it was difficult to determine if the transition from one position (speaker) to another was smooth.

I'm glad it's voice and not tone, so I could equalize all my speakers individually, making them tonally the same. Great!

I agree with this. I find my 45 degree ceiling atmos speakers disconnected from the movie. I have a 7.2.2 The 2 atmos speakers are angled in-ceiling and at 45 degrees. Should I move them over the front L&R? Or replace them with on wall heights which would end up behind the front L&R since the front L&R are pulled 2-3 feet from front wall?

I'd be curious to see how many people with home theaters don't have any rear channels at all - I bet a lot. I can't do them in my room because my stairwell is behind a half wall to the rear of my couch. I have one pair of ceiling speakers placed slightly in front of the listening position. I know I'm not getting the best Atmos experience, but I also know that I never really can. I think your advice is great for people that have the ability to put speakers in the ideal locations, but I think the majority of us are just doing the best we can with what we've got, lol. Keep up the great work!

I suppose the obvious elephant-in-the-room question is this - What proportion of mixing studios (and cinemas) have their Atmos speakers in the corners vs the ceiling?

[@PEM-zt5rd]

Does this in practice mean, change the position of your .4 ceiling speakers to the top corners of your front and back wall and have the speakers face eachother straight ahead (front/back) ?? That way th ATMOS mixes can more accurately place sound above you? Am I understanding this correctly???

[@TechnoDad]

I would toe them in and also aim them down a little. You don't want them just shooting into the middle of the room. Here's another video with my solution - kzbin.info/www/bejne/a3e2c4CLg9KAr6c

​@@TechnoDad thanks Channa ! You rock ! PS: You got mail but no rush tho 🤙 btw hope you are doing well/better... didnt know at the time I sent my mail to you... so Im sending some super duper positive energy your way bro 🙏 USE IT 💪

[@valentinkamenov]

Great video and even greater demos! I can say admirations to you Channa! I will say it for everyone who had doubts as myself. What sound format is better...what speakers placement is better...etc. Well out there is full of "specialists" and "pros" who claims that they know better. What is "better"? My post is not to praise one format or speaker configuration and to disregard another. It is for pure simple field test. I have Denon X6400H (5.1.4 currently) With Atmos, DTS-X and Auro-3D As I have hard ceiling and I am renting, I was forced to place permanently my speakers with classic Auro-3D placement (front and rear hights) When I play native Atmos or DTS-X demos and movies on my system, everything sounds AMAZING and Immersive. But I always had the question, if my upper speakers were in the ceiling. I couldn't find native Atmos channels call out demo until now. So I didn't know how my system should sound. Well here you go now fully confirmed! My speakers setup is 5.1.4 (with hights) My friend's setup same 5.1.4 (in ceiling strictly the same as Dolby recommendation) Same receiver model X6400H With my system the sound was precisely where the diagram was showing! With his setup the sound was in very weired placement...not acurate at all. Recalibrated sysstem several times and same result. We placed temporary at his place a small hight speakers above the main bed-layer to replace the in ceiling. Again calibration and guess what happened... Now everything was in his correct place. It was so much physical efforts to do this test, but the result was solid. So I have a message to all haters of Auro-3D. Forget about the format and all business sh...t between the companies and their marketing. Stop being cocky and defend furiously "in ceiling" as is the Holy Grail. It is NOT! Be on the normall people side. Native Atmos (well mixed on Atmos render) sound acurate on Auro-3D speaker setup!

[@Lowkey_nxthxn]

That’s perfect so even with just a 5.2.2 the height channels are still better then in celling

[@TechnoDad]

I think so!

[@mephInc]

I ran 5.1(2).2 for a little bit but didn't really notice anything "special" so to speak. I switched to a 7.1(2) and enjoy it more. Personal preference perhaps

[@Lowkey_nxthxn]

@@mephInc I did do a 7.2 ones but my room. was just not a right fit for all the speakers it only made sense to run a 5.2.2 but one day I will run a 5.2.4 atmos system since I can only do a 5 channel speaker system in my space

[@bradeinarsen]

Because of this video I did the "on ceiling" height (front and back) with the 3800X and I couldn't be happier. The sounds I hear stay far back where they are placed and they don't move forward. Still need to try Auro3d stuff but everything I've heard so far is completely immersive.

[@rodulfojrcaballero7651]

Works great on my 2019 nvidia shield with denon x4700h, on 5.2.4 (front height & rear height) set up. I have a room limitation as behind my couch is already a wall, so my rear height is just like the voice of of god. I think the auro 3d speaker placement is better than that of dolby atmos.
