7.2.4 Dolby Atmos 4K Home Theater Tour - DIY - 2025 🎥

[@mikeschramm]

Fantastic room! If you love how everything sounds, then it is perfect. In this hobby we spend too much time looking for problems to fix and not enough time loving the rooms we’ve poured out hearts and souls into.

[@KevisFilms]

💯. I truly just enjoy watching movies with my family and not worrying about the system. I’m happy:-)

[@offdacorner]

This is a great comment. And it's something we all need to lovingly be told. I was caught up in the unending cycle of trying to improve my theater. Yep, I was a FOMO addict. I upgraded my projector from the Epson 4050-UB to the Epson LS-12000. Honestly, it turned out to be a significant improvement. So, problem solved right? Nope. Because then I went looking (or in this case listening) for reasons to upgrade my audio. But about a year ago I got serious about fine tuning and calibrating the sound myself. It took me about three days to get it right. And now I enjoy the sound in my theater more than the sound in actual movie theaters (which I find to be so loud that it distracts from the movie). Dolby Digital, DTS-X, Atmos. It all sounds incredible now and I can finally say that I have a sense of immersion when watching movies. Other people also notice the difference. Truthfully, sometimes our equipment might need to be upgraded. But in other cases maybe it just requires some serious fine tuning on our part. That's where learning our equipment's functionality, capabilities and limitations becomes so important. At the end of the day, we enjoy our theaters, that's all that matters. 🙂

Very nice room kevis! Definitely a room to be proud of

[@KevisFilms]

Thank you!

[@bingdong8571]

spacious, seems like a very smartly purchased theater.

[@KevisFilms]

@@bingdong8571 thank you!

[@marvinabugov4579]

Overall, appreciated the tour which I am commenting on as I am watching it right now. Awesome! Very impressed!! Way to go!!!

[@KevisFilms]

Glad you enjoyed it! Thank you!

[@marvinabugov4579]

What I have noticed after following this hobby closely starting in 2020 during the pandemic, is that there is a “pyramid of discussion”. It starts with the basics and lower cost equipment, but over time escalates to ever higher and higher cost products. I have to wonder how much longer these discussions can continue as the market continues to squeeze itself into an ever smaller and smaller market segment. Yes, profits are higher but with an ever smaller segment of people who can afford the overall costs?

[@KevisFilms]

Prices need to start coming down or the industry itself will keep making it a smaller and smaller niche and will continue price hikes to keep up with profits.

[@marvinabugov4579]

Agreed! . . . hopefully JVC and Sony will get the same message UNLESS they see the traditional projector market as one they can do away with entirely and instead move on to newer and even more effective technologies now beginning to show promise, but currently - still too expensive - but for how much longer?

[@naamah-dh]

Many thanks Kevis for your sharing, I love it. I wish I can have a dedicated room one day. For the moment it’s my bedroom. I have to change WAF too ^^

[@KevisFilms]

Thank you! Keep aiming for your dedicated room one day!

[@gab7344]

Nice room I just added a Amp, worth buying , the detail now is amazing, rain now sounds like hail. Its not so much louder but more clarity and detail you get by adding a amp.

[@KevisFilms]

Thank you! I’m getting a lot of similar comments. May test an external amps later this year.

[@lukejhanson10]

Great Setup!

[@KevisFilms]

Thanks, man!

[@ccw-cs6xb]

Good job, we created a very similar setup also with a Spandex screen. Have the Micca speakers for Atmos, but I'm thinking of replacing with an angled type. Thanks for sharing.

[@KevisFilms]

Thank you for watching!

[@Gshiznit74]

It's nice to see an honest opinion on the Valencia seating. It's so commercialised by every other influencer these days It's almost cringy on their credibility.

[@KevisFilms]

@@Gshiznit74 thank you! And, agreed!

[@vibeinstalls9890]

Great Job Kevis , Room is looking good, great detail and authenticity for the hobbiests to relate to. Wish I could check it out in person. How do you measure your room ? And calibrate your Subs ?

[@UEGGOTH]

What did you use to hang those atmos speakers? I have been wanting something like this for my living room since I really don't feel like cutting holes in my drywall and running cables. I love the setup. I wish I had bought a house with another room just so I can have a home theater and not have to use my living room. I started mine in the bedroom and my wife said it was too loud so, I had to take it all downstairs :(

[@KevisFilms]

I screwed a 2x4 (about a 1’ long) on floor joist, then inserted the speaker box (which covered the 2x4) and screwed the top side of the box into 2x4 support. Not sure if this makes sense but it does on paper.

[@flyers10az]

Room looks great. Add 2 more psa aubs for evenness.

[@KevisFilms]

I’m really happy with my PSA subs. 2 more would be awesome!

[@marvinabugov4579]

I have the same Marantz Cinema 50 receiver and I just love it particularly given its use with Auro 2D. Find it better than Atmos overall but many Netflix shows only permit Atmos. Calibrated it using basic Audessy and find it quite acceptable. As for seating, I prefer valeur cloth. Less clammy. My seats are still going strong after 15 years of fairly heavy use: my daughters/friends and now my grandchildren.

[@KevisFilms]

I still have not tried Auro in my theater. For the win on the seating! Anything lasting 10+ years and getting constant use from kids a BIG win :-)

[@marvinabugov4579]

Yes, I am quite pleased and from a manufacturer not of the type that are being promoted these days. Didn’t know what we were doing back in 2008 when we built our home theatre professionally leaving it to the designer/builder, but sometimes you get “lucky”.

[@marvinabugov4579]

My basement has an HVAC oddity in the ceiling that precludes my using overhead speakers. So Auro 2D does a lot to compensate for my oddly shaped ceiling in one corner of the room.

[@garryhammond3117]

Your room looks great. Thanks for the great tour - We all have to work around what we have to work with. Luckily, I have a 24 foot square room with 8-9 foot ceiliings depending on where you look. Question: How far s it from your PJ lens to the screen? - You might want to minimize this for more brightness. - Cheers!

[@KevisFilms]

Thank you! Lens is about 19.5 feet from screen. I’d like to experiment with some better screens later this year and see how they may bring up brightness as well. We will see. But so far, this projector is plenty bright for sure.

[@MichaelHollmann-c1j]

As for the lighting in the Valencia seats, did you plug a phone into the USB? It cooks the controller. It’s a fairly simple fix once you do you it once, but extremely poor considering it needs to be done at all. After all that’s what it’s for but doesn’t work as intended. I had it happen to mine.

[@KevisFilms]

I have plugged a usb cord to charge my phone. What was the fix?

[@MichaelHollmann-c1j]

@ replace the button control pad. Valencia will supply the part if you still have warranty, if not under warranty there’s probably a cost for it. The wiring is easily accessible and labeled. Separate the back and seat sections, flip the seat section on its side, the bottom fabric is held closed with velcro. You shouldn’t have trouble, seeing as you’re a DIY kinda person. They will send you a video to give you an idea how to do it.

[@darshankansara8000]

FINE

[@KevisFilms]

Thank you!

[@scott1063]

I’m still looking for some feedback on the MTM212M’s, they are significantly more expensive. Ground loops can happen with any amplifier and one single solution doesn’t work in all cases. It is absolutely fixable and you need to fix it, not just turn the gain down.

[@KevisFilms]

Agreed. Will be working on ground loop this weekend!

[@shaolin95]

PSA are notoriously bad with amp noise. I had 4 and all of them had it to some degree. None of the countless subs I have tried before or after had such issues

[@KevisFilms]

@@shaolin95thank you for sharing.

[@byron19800]

I still think separates should be the final goal in any serious home theater. I never liked the idea of a single box handling absolutely everything, just for the sake of convenience. There are a lot of potential problems with a box that tries to do everything you need, all at the same time. In the end, it's not just about tons of power, it's about peace of mind and not worrying for the future. It's about real dynamics and superior transients. It's about reliability, a good power amplifier should last many, many years without breaking a sweat. Don't overlook the used market, you can buy really good gear for a fraction of the price. Currently, I have a Marantz AV8802a pre/pro and 4 power amplifiers (2 Denon monoblocks, a 3-channel Carver and a 5-channel Emotiva), all purchased from the used market, for a total price of a new, mid-to-high AVR.

[@KevisFilms]

Thank you for the feedback. I’m not opposed to testing some amps later this year and doing some comparisons as well. I’d be definitely be looking out for deals/ used market as well.

[@melraine919]

Well done 👏🏼👍🏼💪🏼✊🏼 I would love to get my hands 🙌 on them KRIX’S 1470 SPEAKERS 🔊 the only trouble is I live in England UK 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧 I think that there are a Australian company that makes them❓

[@KevisFilms]

Yes, Krix is from Australia. The company I bought them from is still out of stock here in the states. Not sure they have tried to expand beyond Australia so much.

[@melraine919]

@@KevisFilms Thank you for your reply I’ll try and look 👀 into getting in touch with KRIX’S by email 🤞🏼 To find out whether they have a supplier here in the UK

[@FrankieKennethL]

Kevis. Muy impresionante y felicidades en tus selecciones. Una recomendación: I noticed yiu said ur gain on the subs is turned down. I suggest you dont do it that way. For gain sequence and staging, it is recommended to have your gain (it’s actually an attenuator) at about 75-90% and just control the output via your trim in the processor. The reason is signal clipping. You don’t want your amp to clip any signal that the processor is ‘sening’ for output. The attenuator could do so. asi no corres riego.

[@KevisFilms]

Gracias! Thank you for the good info! I will try it one my end!

[@shaolin95]

Get better Atmos speakers and place them correctly then you will hear what true atmos can do

[@KevisFilms]

Where do you place your atmos speakers?

[@bigjack79]

Great space. You don’t need amps. As long as the receiver can handle the impedance load, which marantz can. Save your money Dirac bass control would be the biggest up grade that you can do. Or adding 2 subs in the rear. Also. The gain noob on your sub just lets the receiver know how much voltage to send in. It’s not a level. What’s the sound transmission loss from the spandex?

[@KevisFilms]

Thank you! Really looking forward to trying Dirac Live + bass control at some point in the next couple of months. I would have to go back and see my measurements, but honestly, from sound memory it feels like I sound transmission was really minimal. I did have to adjust my distance from speaker to screen, but after I did it sounded fantastic!

[@wendellwendellb339]

I don’t know why someone said you don’t need external amps. The Marantz Cinema 50 gives you 110 watts, 2 channels driven. You can get (if you so choose) an amp that will give you that wattage, all channels driven. Just something to consider.

[@KevisFilms]

Thank you!

[@mfkhometheater7742]

The room is looking great! With those high efficiency speaker systems you don't really need more power. If you ever did add an external amplifier you wouldn't need to do more than the front three on the external amp. People tend to be obsessed with power not realizing that it's volume displacement that determines a speakers output, not the amplifier power capability. Near resonance it may take only a few watts to drive a woofer to its mechanical limits, it's the higher frequencies that demand more power for a woofer, not the low. There will be a frequency where the woofer can never reach the mechanical limit because it will fail due to exceeding thermal limits first. Driving speakers with high power heats the voice coil causing impedance changes and thus non linear distortion so having speakers that require less power is a good thing for more reasons than just not needing to add additional amplifiers. Great job on building your system, I expect it sounds pretty fantastic!

[@KevisFilms]

Thank you! My thoughts exactly on external amps. I have never turned my volume knob below -10 and still sounds super loud.

[@jimcameron1234]

QB1000 only 5500€ in Germany

[@KevisFilms]

$3,000 more dollars here than the ls12000

[@douglasglover1406]

Trust me my friend, if you have PSA & Krix speakers then you need external amps. I would suggest at least a 7 channel amp. That will make a world of difference for your speakers. Of course they’ll be louder but it’s about channel separation and clarity no avr can do because they’re under powered

[@KevisFilms]

I appreciate the feedback. I will have to test it out on my end. Any amplifiers you recommend?

[@naamah-dh]

@@KevisFilmsi think the best amp for bucks you can have it’s buckeyes with nc252p modules. They are very good amp for the money.

[@naamah-dh]

Even better with nc502mp modules, you can transform the sound performances of yr HT

[@KevisFilms]

​​⁠I’ve good things about buckeye amps. Thank you!

[@bryanwarner561]

​@@KevisFilmsI would also look into Emotiva power amps. Great bang for buck and superb customer service.

[@therealshanelee]

I used a Humdinger DC Line Blocker by Van Alstine to get rid of the hum on the PSA subwoofer I had. It might work for you too.

[@jimcameron1234]

PSA Speakers and PSA Subs FTW!!!!

[@KevisFilms]

I love my PSA speakers and subs!

[@marvinabugov4579]

I fail to understand “generally” why some people like their sub woofers SO LOUD? Such as the fellow who operates “base brings us together”. I have my three budget subwoofers set at 3 or 4 on the loudness scale and find it quite acceptable: well balanced overall as part of the whole system. Any louder, and yes I can feel the effect in my seat or in my chest, but I find it rather distracting - let alone what it does to my “hearing”. Your ears can only take so much. Ok abuse them when you’re “young(er) but wait until you are older and where the effects of your obsession will emerge. Fair to say: I don’t think you will like such things as hearing aids etc.

[@KevisFilms]

I don’t disagree. I think on the home theater side folks keep aiming for single digits and loudness. I’m happy with a more commercial sound to my room that stays below 82-85 db peaks. Not looking to lose my hearing with this hobby:-)

[@vibeinstalls9890]

Great Job Kevis , Room is looking good, great detail and authenticity for the hobbiests to relate to. Wish I could check it out in person. How do you measure your room ? And calibrate your Subs ?

[@KevisFilms]

Thank you! I use audyssey and OAC EVO one script. I did a video on it a while back. It really has given me some of the best sound in my room. Might look into Dirac Live/Bass Control at some point this year to test and compare with audyssey in my room. I also REW and umik 1 to double check final measurements. Thank you!
