Is Audyssey Accurate?! How to Calibrate Your Home Theater the EASY Way

Is Audyssey Accurate?! How to Calibrate Your Home Theater the EASY Way *CORRECTION* I made a mistake. When setting speaker Levels CLASS C weighting is preferred. C weight has a flatter response at low to medium frequencies. Since voice is around 80-260hz class C is Great for that. Class A is better suited for high frequencies. Sorry and Thanks!! Here is a quick video about how to manually calibrate your home theater levels with an SPL meter and how to set the speaker distances. The RMC-1 is awaiting its dirac release and here is what I found works great when auto calibration like audyssey is not available or you want to improve upon it.

*****I MADE A MISTAKE :( Class C weighting should be used for checking your speaker LEVELS. Class C is better suited for low to medium frequencies since it is flatter on the frequency response curve. Class A, on the other hand, is better suited for high frequencies and less accurate at lower frequencies. Sorry for the confusion. I hope this makes it out to all of you :)

[@calinubro]

Because you are the man, and I trust that you know what you’re doing, I bought the same meter on Amazon; thanks for that link by the way! But I’m still confused on if I should use A or C weighted on my 7.2.4 layout.

[@ThatHomeTheaterDude]

Wil Thomas I made a mistake. Use class C weighted on the dB meter. Works great for cal ;)

[@101chevymann]

So just to be clear. Use c for all speakers including subwoofers. Also what was the make and model of spl meter

[@ossiebacchus7110]

Never set the volume to 0db when setting up before. Sounds soooo much better. Many thanks for this, think I'll setup manually from now on

[@tatts4life838]

When you mentioned using the iPhone measurement tool I was gonna mention that it’s usual off by 1/4”-1”, but you did notice that. I do love that it gives that AR look to all your measurements though. One thing I don’t like about auto calibrating on my Denon AVR-x6300h is that my 2 subs weren’t as punchy as I wanted so I did bump up those speaker levels

[@xjmzrq]

[@Test-Pilot1194]

If this is your first time with Dirac live Chris, what makes you so sure it’s going to be...”superior” to audyssey and the others out there?

[@sebulbathx]

I agree about the importance of calibration. I know a few people with good systems and when I tell them it's important to calibrate levels and distances they shrug it off like it doesn't make any difference. The answer might be "why? I hear sound in all speakers anyway" and I try to explain why but they don't seem to buy in the benefits which is, imo, a big waste of money. You might not hear when it's wrong but when you compare to when it's right you hear the big difference. If you don't bother with these kind of things I think it's better to just buy a soundbar or just crank the volume up on the tv's speakers tbh.

[@SVSpc13]

I juse the C - weighting dB meter measuring to measure so wide a response as possible when calibrating speaker level.

[@DarrenJamesNI]

Whilst filmed a while ago, still a great resource. Quick question with respect to setting subwoofer levels. Once set, do you ever find yourself needing to adjust the volume of your Svs via the Svs onboard amp?

Found this good when using SMS-1 & Rotel Quote: Originally Posted by craig john Hi Mark, If I may, I would like to elaborate here a little bit... (OK, well, maybe more than a "little bit!" ) First, the SMS-1 is a great device for helping to optimize subwoofer placement in the room prior to any EQ or calibration. To use it for this, just turn off the speakers and play only the sub. Disable all EQ in the SMS-1 and set everything else to baseline. Then place the mic at the primary LP and move the subwoofer around room while watching the FR on the OSD. Place the sub in the spot that measures the flattest without any EQ. This will make it much easier to EQ the system later, as you will need less cuts or boost to get a perfectly flat response. Second, when setting levels, there are 4 different level settings that need to be accounted for: 1. Master Volume Control 2. Subwoofer and Speaker Trims 3. SMS-1 Level 4. Subwoofer Level These will all interact and they all need to be taken into account prior to doing any calibrations or EQ. To set the levels, and then EQ the system with the SMS-1, I suggest the following progression: 1. Start by setting all trims in the receiver to 0. (We'll come back later and re-set these for calibration purposes, but for now, set them to 0.) 2. Set ALL speakers to Small AND all crossover frequencies to 80 Hz. Reasons: The SMS-1 expects the use of Bass Management, which is what you engage when you set the speakers to Small. Therefore, to get proper results from the SMS-1, you need to set the speakers to "Small" and engage BM. The SMS-1 can *only* EQ the subwoofer channel. It can NOT EQ the speakers. This is very important to realize. Any filters set above the crossover point will have little effect on the subwoofer output and minimal effect on the overall response. Limiting the range of the subwoofer channel by using a low crossover point, limits the range available for the SMS-1 to EQ. IOW, if you set a 60 Hz crossover, the SMS-1's EQ will only be effective to 60 Hz. Therefore, set the crossover as high as possible without localization of the subwoofer, which is almost always 80 Hz. Page 42 of your manual, (see below), describes the Bass Management scenarios for your receiver. You can either use a "global" crossover for all "Small" speakers and the sub, or your receiver allows for different crossover frequency settings for the subwoofer and the speakers. The subwoofer crossover is really just an LPF, whereas the global crossover is an LPF and an HPF at the same frequency. IMO, you should use the same frequency for the HPF on the speakers and the LPF on the sub. Therefore, I recommend you use the global crossover setting of 80 Hz, for all speakers and the subwoofer. Also, set the "Stereo" mode to "Speakers = Small". This will engage Bass Management for 2-channel sources and make your subwoofer active for 2-channel content. This is *very* important for optimal EQ with the SMS-1, as described below. The Phase Control on the SMS-1 is centered at 80 Hz. While it is better to use the receiver's distance setting to effect the response around the crossover point, if you do want to use the SMS-1's Phase Control, it will only be effective with an 80 Hz crossover. 3. Next, on the SMS-1, select Preset: Setup and set all EQ bands to 0. (A default reset is the easiest way to do this. See Page 41 of the SMS-1 User Manual, linked below.) 4. Set the SMS-1 Level to +15. Reason: This is the setting for "Unity Gain" in the SMS-1. The SMS-1 is not an amplifier. You don't want to use the SMS-1 to add gain to the signal. You want it to add or reduce the gain of various frequencies *relative* to the average level, but you don't want it to increase the overall average level. "Unity Gain" means that there is no gain across the device, and the output signal is the same level as the input signal.) 5. Set the Subwoofer Gain Level at it's lowest setting. (We'll turn it up later.) 6. Turn on the left front speaker test tone. Adjust the receiver's MVC so the left front speaker reads 75 dB* at the primary LP. This MVC setting will be the "Reference Level" setting from this point forward.** Remember it. 7. Without changing the MVC setting, shut off the left front speaker and turn on the subwoofer test tone. Turn up the gain on the subwoofer until the SPL meter at the primary LP reads 75 dB. The SMS-1 should also read an "average" level of about 75 dB. (Once you've set this, you should never need to adjust the subwoofer's gain setting again, unless you move the sub.) 8. Now, go back and calibrate all of the speakers to 75 dB at the primary LP. Use the receiver's trim controls as described on Page 43 & 44 of the manual. Once you've done this, your system is fully calibrated for levels, and all of the settings are optimized in each device. 9. Proceed with manual EQ with the SMS-1. Put the receiver into "Stereo" mode. EQ the sub in isolation, (with the speakers off or disconnected), getting it as flat as possible up to the rolloff point of the speaker/subwoofer crossover you set in the receiver. (Remember that in Step 2 above, we set the "Stereo" output to engage Bass Management. Even though the speakers are off here, the bass from the L/R channels will still be re-directed to the sub.) (Remember also that any slider bands set above the crossover point will be wasted, so move them all over into the range below the crossover point.) 10. Once the subwoofer is EQ'd, turn the subwoofer test tone back on and reset the level to 75 dB. However, this time use the SMS-1's level control to adjust the volume to 75 dB. This will reset the SMS-1 for exact Unity Gain. 11. Finally, turn the speakers back on and evaluate the response around crossover point. Adjust the subwoofer distance setting in the receiver to optimize the response around the crossover point. 12. Re-check the full system calibration to ensure all speakers and the sub are at 75 dB. Once you've done the entire process above, you'll have a fully calibrated system with optimized frequency response of the subwoofer. I suggest you try to live with that system for a few days or weeks. Some people are so used to a bloated or "hot" subwoofer level that they feel the bass is "missing" with a true "calibrated" and Eq'd level. Nonetheless, once they re-acclimate themselves to "flat" bass response, they begin to hear detail and articulation in the bass that was previously overwhelmed by bass bloat and boom. Having said that, some people just don't "like" a flat FR of the subwoofer, and they prefer a rising LF response. There is nothing wrong with that, and everyone is allowed their own preference. If you're one of those people, you have a few options. The first option is to just raise the MVC. This will raise the overall system output, but you should also get closer to the bass response you are looking for. (This also assumes that the rest of your system is up to the task. If it's not, don't try to get bass response at the expense of your speakers! ) If that is still not enough, and you want to raise the subwoofer's output above the rest of the system, I suggest you initiate the Submersive's DSP Program 2. This adds a rise in the response below about 40 Hz, with 3 dB added at about 20 Hz. This should add the feel and kick you are looking for. You can view the effect of Program 2 by watching the response on the SMS-1. It should look like a rising response above about 40 Hz. If that's *still* not enough, the third option is to raise the SMS-1's level. This will take you above "Unity Gain" on the SMS-1, but *judicious* use of the control should not be problematic. 3 to 6 dB of level increase should be taken in stride by the Submersive. If the above suggestions don't get you were you want to be, then the only hope for you is another Submersive or 2 or 3. Craig Footnotes from #6 above: *The Rotel uses -30 dBFS for it's test tones, so the test tones should read 75 dB on the SPL meter, ("Slow" setting and C-weighting.) **The Rotel appears to be a "relative" MVC, (it goes from 0, (Off), to positive numbers), as opposed to an "absolute" MVC, which sets Reference Level at 0, and negative level settings indicate the dB below Reference Level.

The whole issue I see doing it manually and using advanced auto calibration Dirac Live, Audessey, MCACC Pro etc the other aspects of tuning like Phase corrections and alignment, standing wave corrections and a lot more that gets adjusted and also is dynamic in nature to adjust for source. Manual to me is only to fine tune the distances, the cross over settings etc, so will use it as additional verification step than main way of setting it up

It may sound stupid to you, but I have to ask :) How much do you set the volume Knob on the AVR's remote while doing this manual measurement with SPL? I've read a few sources, they said 0, but when I bring it to zero from the remote, no sound comes out even if we increase it anyway, so I wanted to ask you the truth.

[@ebroadnax1]

Looking closer at your center, I can't tell if its angled. I have the same L/C/R with a PB 3000. I'm using the same stand and have my center on top with metal cones (flat side down x 4), that have rubber tips as supports to get the center a little higher and off the glass and inline with the tweeters of the mains. They came off an old pair of speaker stands I no longer use. Looks kinda cool. Also, I flipped the screens over on my mains and attached them upside down. Old screens from previous speakers have gotten tattered in the past from being stored in a closet somewhere:) Thanks again for all you do. Made a shopping list for some more tweaking of my gear/room based on this video and the the one you did for SoundAssured. .

Great vid -- I have a meter coming today and am excited to do this calibration. I've done the Audyssey calibration and it set my speakers all in the range of -6.0 or lower. I find myself having to crank the master volume on the amplifier much higher now to get the punch and presence I want. I understand the meter is used to make sure all my speaker volumes are equal (same db level using the meter). Here is my question: what would happen if I boosted all the speaker levels up to say -2.0 or even 0? Will it allow my speakers and amp to work harder and produce more sound, or will it also screw up my Audyssey-imposed room corrections?

Is it normal to have speaker level differences of 1db or more between left and right. I ask because Audyssey keeps picking up one speaker as always being quieter. I notice you have set your speakers different levels. Should it be identical if room is symetrical and cables etc are same?

Thanks for the video. I have a marantz av receiver. A few years old but does everything I need. It has Audysey (complete with cardboard mike stand... What is that all about??). If I notice the auto room correction gets the speaker distance/crossover slightly wrong: can I tweak the measurements myself (using tape measure and dB meter) and still get the Audyssey working correctly? Or is Audyssey locked to the measurements it took?

[@ThatHomeTheaterDude]

ideally, the time it takes the AVR to send a signal to your speakers and then interpreted by the mic dictates distance. This can vary from line of sight distance. There are different people that swear by either method. just pick one and move on. You can change the auto calibration that audyssey does after its completed

If I set MV on 0 than SPL meter is not giving any effect in case of MV 1 to 100. If I set it on 60 to 65 than SPL meter start giving effect. If I changed MV in DB and set it to 0 than I have to set DB level in minus or more than -10 but there is -10 is max level. For achieving 75 DB level on speaker 60 to 65 MV is giving result.

Guys, I just setup my new Marantz AV7705 today (Just purchased and a 2nd SVS PB3000 subwoofer) using a Radio Shack SPL (Analog) if you can still find one. It should be setup at C weighted using slow response per Audioholics youtube video. I ran Audyssey auto calibration and when it was finished, I replaced the MIC on my tripod with my Radio Shack SPL Meter and set the Marantz master volume to 0db. I then adjusted all of the speaker trim levels to 75db. I then worked with SVS support to dial in the subwoofers. Now it sounds great. My next step is use REW to finish my subwoofer calibrations. I've never used REW before so it should be interesting. Good Luck Guys PM

[@andrewpolitano]

C-weighted slow will be akin to an average level. This is what you should be using for calibration for level adjustment. As long as your speakers aren't jumping erratically more than one whole db at a time, you're fine. Minor discrepancies are fine and you're likely seeing room issues such as modal issues or reflection issues that confuse the meter for a hot second, making your reading inaccurate. More time may be required for an accurate read on speakers since you're essentially taking an average response of level. Subwoofers will jump around due to how standing waves interact at the location of meter but again, just get it as close as possible.

Love the setup and the idea of using the iOS tape measure. However I was confused what was being measured with the microphone and how you need to then make adjustments. Is it you just want all the speakers to be the same decibels so if it one speaker is lower you add decibels to it.? Thanks.

[@ramonbarajas2813]

You are measuring decibels, his are at 75dbs, obviously the higher the decibels, the louder. I set my receiver at 0.0 volume and cycle my speakers to hit 80 decibels.

[@ThatHomeTheaterDude]

Ramon Barajas right on Ramon that’s how you do it.

[@ThatHomeTheaterDude]

JimmyDee go to levels on your avr /processor. If there is a low med high feature on the levels set it to med. if the low med high is absent then go into levels. Go to your receiver and turn the volume up to 0.0db. If you don’t have this scale then usually 75 -80 is what’s used on your volume. Then in the speaker levels you adjust them up or down to all reach the exact same dB on your dB meter. Usually the standard is 75db on the readout of the dB meter.

Ok thanks for clarifying, I will give it a go.

[@thepiecesfit5049]

Didn’t see whether this was mentioned but Audyssey at least is temporarily disengaged when you run the test tones directly on the receiver. You need to instead use a disk with test tones like DVE or Spears and Munsil. It makes no sense to use the AVR when your calibration is disabled. Best to use the disk on your BD/UHD player with the calibration enabled.

You should mention , the master volume on the preamp or receiver should be at 0. that helps a lot.

That depends on what you want your outcome to be. If you want your 0 to be a true reference level, then you would have to calibrate at 105db.

All amps are 1st control by onkyo PR‑SC5530 than all out puts go to mini dsp for crossover and eq and then output goes to all 7 amplifiers which are balanced inputs.

Hello again. I love your set and hope to hit that mark someday. Why do you have your center speaker sitting lower than the tweeters on your mains?

[@ThatHomeTheaterDude]

SO you want me to raise the center speaker to mimic the same height as my towers? So i would be looking at a speaker in the middle of my projector screen?

[@ebroadnax1]

Never that. I've faced the same issues when I had my projector hooked up. I'm using a Vizio 75" P Series until I can afford to upgrade my projector. TV is mounted just high enough for my center to be about an inch or two from being inline with the mains. No question, you know what you're doing. A slip of the eye on my part. I kinda put the video image out of mind at the time because there was no image, duh? Remembering when I had a screen (10 years ago, sigh), I had the same restrictions because of its size (120 inches). Keep doing what you do and I'll keep watching and learning:)

[@PROUD_CANADIAN78]

I'm new to this and had a question about A Weighted vs C Weighted. I've seen many say use C Weighted for home theater including the Subwoofer. Is there a major difference? Is one better than the other? Also I have a Yamaha and I used Ypao to configure my room and speaker distances for me and it automatically adjusted the volume for each speaker. Should I then afterwards use an SPL meter to readjust the volume to 75db after the Yamaha does its own automatic settings? I manually went back in and changed all my speakers to SMALL and I set the crossover to 80hz already.

[@ThatHomeTheaterDude]

i made a mistake. C weighted is best for speakers and subs. I stated it wrong in the video...

[@gabemartinez1012]

How do you level the gain on dual subs? Do I set the av level to 0 and then use the SPL to measure one sub at a time. And set them to 75 db, and then turn both on and use again the SPL to get them at 75? Do i make since lol

[@ThatHomeTheaterDude]

its the same as one sub, just do the levels independent and keep the gains on the sub the same

[@Bryan-hd7nm]

Great video! Why is the subwoofer distance always so off and farther than it actually is? Should I adjust it to actual distance I get from a tape measure? Thanks!

[@shaapoopiee]

It's not measuring the distance, it's the time it take for the sound to reach MLP

[@Bryan-hd7nm]

Andrew Mitchell so the tape measure works well for that? Because my sub is next to one of my mains and it measure the sub as being so far more than what it actually is

[@ThatHomeTheaterDude]

try moving the distance on the AVR setting and see if it sounds better or worse. Sometimes subs take longer or shorter to get to the MLP. ALso this is an easy way to modulate the sub frequency response curve in your room

[@uceddiemo]

What I’ve learned from using a SPL meter when setting your sub distance with the meter, I went from actual distance and added a foot and looked at the meter, sometimes the meter would drop a few dB. And sometimes it would jump a few dB. , I continue adding a foot to the distance and check the meter to see what gave me the most dB. That’s the footage you want to stick with when setting subwoofer distance with the SPL meter

[@shaapoopiee]

@@Bryan-hd7nm No it doesn't, the delay is caused by the subwoofer dsp. The dsp can add around 100ms, which is why an avr has further away

[@disabledcompany]

what's your crossover frequency settings?

[@chuckfriebe843]

The auto calibration will set the speakers at its own crossover depending on what it hears from the speakers. THX is 80hz, but not all speakers are able to roll off below that frequency. If you have THX approved speakers then you set it for sure to 80hz.

[@Buxtonphil]

why do you use 75db as a reference point?

[@akaredcrossbow]

Hello, I have a Marantz sr8012 and my front left and right tower speakers are 9.11 feet away from my listening position. The speaker distance in the Marantz menu only goes up to 9.9 feet and then changes to 10 feet, so no 9.10 or 9.11 feet. If my distance is 9.11 feet should I set my distance to 10 feet or 9.9 feet? Hope you understand my ramble! Thank You!

[@ThatHomeTheaterDude]

it really depends on the latency of the speaker, sometimes line of sight does not equal the distance on the AVR. id try 9.9 for now

[@akaredcrossbow]

That Home Theater Dude Thank you! I’m having some other big issues with Audyssey now! It is setting my front left and right crossovers to 200hz, my center to 150hz and my side and back surrounds to 100hz. I’ve heard that it’s ok to go up with crossovers, but not down, because of loss! I planed on seeing 40-60Hz like I have in the past with the same setup, same room and bumping up to 80hz. The only things I have changed is moved my front left and right towers forward and out about 2 inches and my center back about 3 inches so I can have a good surround circle with all of my speakers.

[@omc951]

You mentioned your opinions on Audyssey calibration but didn’t mention the XT32 version that lets you set curves and filters. In my opinion Dirac Live, MiniDSP, REW are all superior than most AVR calibration systems but require a lot more time and are not simple. Audyssey XT32 is quite a bit more sophisticated than the takedown version or other AVR calibration systems (YPAO, MCACC) and got me great results in my difficult room, and let me do adjustments to my curves after the initial measurement with relative ease and all on my phone. I believe the convenience to performance ratio is quite high on Audyssey XT32 on top of being attached to some great hardware in the flagship to midrange Marantz/Denon lineup.

[@ThatHomeTheaterDude]

I get what you are saying, but i just did the cal on the marantz and it was way off. Only one speaker level out of 16 was proper, the sizes were all different, the crossovers were wrong and the speaker sizes were wrong. Im sure on yours everything was perfect but my experience with them is that they arent always the most accurate. Im sure the paid app for your smart device helps out a ton, i just have not used it to optimize the PEQ.

Don't for get Rew has its gone generator you can run pink noise and set the -db off set to your needs to test. Then determine if low, medium, or high works best for your needs. Or with audyssey what volume you need to set the AVR at to be equal too. Example my x4200 was off like 4 db, but I also found out that the test tone also wasn't the same signal level. So determine what your base level is at of your avr or processor's pink/white noise.

I use all 8 points of measurement, but they are all within the parameters of my chair. I’ve done the tripod thing, moving it around within 2 feet, frankly I’m getting better soundstage results with my method. Here is a question, with Denon & Marantz, they use one foot as 1.0-1.9, 2.0-2.9, 3.0-3.9, and so on. We all know that a foot is 12 inches and not 10. You may want to suggest people wear headphones while doing the test tone for setting up volume levels. 0.0 is extremely loud! My AT-M50x work great to protect my ears.

Thank you for this video, unfortunately the measure tool on the iPhone is not accurate. It’s always of by a couple of centimeters (Europe). And for audio, that’s a substantial difference. Room calibration software are always on point when it comes to distance measurements. Also two subwoofers on the front looks good, but is the worst placement for a good response. You are hearing a fraction of what these beasts can do. Why limit yourself?

sermerlin1 the bass is not evenly divided in his room. If he has dips in his response on the left sub, chances are that the right one has the same response. When the right sub would be positioned diagonally in the back, his response could be much better.

[@sermerlin1]

@@WIZARTthe Well... I don't think that's how air moves. If it was only one sub at the front left and it had frequency dip in certain spot... The second sub that is on the front right will fill in those dips. You can try it yourself. Move to the left of the room and to the right of the room (if your sub is in front left or right) and you will notice dips and peaks are certain to one side of the room and when you add another sub to to the front it will fill in those peaks as it is opposite to the first sub meaning all the dips and frequencies that the first one has will be filled in by the second. You will get best frequency response of dual sub by placing them in the middle of the room at each side but placing them on the front or diagonally it really depends. In both cases it will work and you will not have any lack of frequency response.
