I'd like to get a 10" sub that could fit well into my setup instead of being this separate entity/personality with a mind of it's own. A big, boomy, sloppy mess it was.



I was battling poor dialogue volume from my center and was finding disabling Dynamic EQ helped that out. I've gone back and forth on all of these things, multiple times. I have aimed my center upwards to my head, which helped, but everytime I increase the center channel volume, it just seems to wreck what Audyssey was trying to do. Things don't have a balance anymore - all I hear is my center channel and yet, I still have trouble picking up dialogue sometimes. I am hoping a newer XT32 DENON AVR with separate dialogue control might help things out a bit. I'm also hoping my new RC-64II center might have a slight edge on my RC-62 center.
I had the same problem, it was because of bad calibrations, I tried putting blankets down, ect. I also have the klipsch rc2. Great center. Really pay attention to the first calibration especially and have a receiver with xt32. Make sure all your calibrations are precise with the mic centered perfectly centered and straight up. If your center is weak like mine was it's bad calibrations. Make sure your mic is at least a foot or more from your back cushion. I found that deadened the center when my mic was too close to the back cushion. I did about 20 calibrations before I figured everything out. I also bought an SVS subwoofer which is amazing. A pb 1000 or 2000 will do the trick. If you want an even better one go for it. When I first started I hated all he settings, they made my diologue bright, or muffled. Now when I use EQ the dialogue gets a little louder as intended and everything is louder as it should be. Keep trying and when you have detailed surround after a calibration build from that. See if you can nail one with a bright center and combine the two with what you did. Tinker with distances, tinker with room set up but for me with the center the most important thing was precise measurements from the couch. Not sure of your mic placements but this helped most for mine. Try this website and mic pattern.

I use recommended mic pattern 101. Worked perfect and my center detailed and crisp. I had problems for over a month, tried this and it worked nicely.

101, 101B, 102 - Best Image Clarity and good frequency response coverage. All dimensions are relative to PLP Center


Just filter Recommended Setup Mic Patterns, little further than midway down the page. That should help a lot

The best thing to do is make sure you turn off all your wifi, cable, cell phone, clocks, make sure it's totally silent, and make sure your mic is PERFECTLY centered and level and away from the cushion and should be fine.

I just bought these, lol.


42.5k for q3 speaker. Umm that's a little out of my price range ATM, lol

If you are new to Audyssey I suggest you start by reading the '101' and FAQ, both linked in my sig. They should answer all setup questions for you.

If you have a specific question, post it here and you will receive a good number of suggestions I am sure.

Audyssey may find your speakers to be full-range and will want them set to LARGE. You don't have to disagree with that, if your new receiver has enough power to run all of your speakers at your desired volume levels. Setting speakers to SMALL lets the subwoofers' amps do most of the heavy lifting, since bass frequencies use most of the power.

Audyssey will set 0 dB as reference-level (75 dB). This is not the same thing as the 70 dB figure you get on a sound pressure meter. "Reference level" means each speaker level must be adjusted so that –30 dBFS band-limited (500 Hz – 2000 Hz) pink noise produces 75 dB sound pressure level at the listening position. In other words, the maximum level you will get from a system set to reference level is 105 dB.

When I upgraded from my RB-81's to the RF-82's and re-ran Audyssey it detected my mains as Full Range. So you are saying I should set them to Large or even Small? Is that going to change any other settings or do I also have to change other settings as well (like Crossover)?

It's up to you, I have the 82 2's and after the test it also set them to large and 40 HZ, I switched them to small and 80hz since I have a good subwoofer. I am also bi-amped. If anyone here can look at my question in the marantz thread I would appreciate it

I just went through the FAQ and decided to set my Front / Mains to Small and set all of the crossovers to 80hz to see how that goes when watching a move. The settings before were Large with "Full Range" for the fronts and the Crossover for all my other speakers were at 60hz.

I have the rc'62 2 and rf 82 2's so we almost have the same. I have two towers for backs/surround and a 7008 receiver. The fronts sound clearer when u set to 80hz and small because they focus mainly on the highs. I find when the sub was on and the speakers were set to large and 40HZ it was way to much bass all the time. Our fronts are very good at producing bass.When I make the adjustments it's much crisper all around

Modern D+M AVRs and pre/pros have a very user-friendly "setup assistant". It'll lead you through connecting your speakers and input devices and running the Audyssey calibration procedure. For example, all of the speaker outputs are connected by individual electro-mechanical relays which the setup procedure makes use of when it tells you to connect a particular pair of speaker wires. This helps to isolate wiring problems.

(Unfortunately, there are some bugs related to overhead speaker calibration in the initial release, so you probably should run it again after it has helped you configure the network and download the current firmware update.)

Also, please take the time to read the Audyssey 101/FAQ (<-- this links to the FAQ). Their recommendations have been developed over a long period of time to help you get the best results. The instructions provided in AVR manuals are woefully inadequate.

"Plenty of very low bass" is not necessarily the same as "accurate bass". In particular, if you haven't been very careful when setting the low pass filters in your subs to match the natural low-frequency fall-off of your main speakers, you might have gotten used to the "bloated" bass caused by the interactions between their overlapping frequencies. Often people who've gotten used to inaccurate, boomy bass tend to feel that Audyssey's results are "anemic".

Audyssey's calibration is done at 75dB. It doesn't matter what level is used for a calibration, so long as it's consistent. 75dB is quiet enough that it doesn't bother most people, and its individual calibration pulses are brief.

There are several reasons for choosing a crossover frequency of 80 Hz, which you might want to consider. Some are related directly to sound quality, others more to electronic capabilities.

1. Room modes: Low frequencies interact with your room's dimensions, resulting in peaks and nulls in sound levels at various locations and frequencies, potentially up to about 200 Hz depending on the size of the room. This is quite unlike how higher frequencies interact with the room's surfaces. You have to place subwoofers so they produce the flattest response at your main listening position. The optimal locations for subwoofers usually are not the same as the optimal locations for your main speakers.

2. Speaker capability: Distortion increases as you push speakers to the limits of their frequency performance. By offloading the lowest frequencies from the mains and surrounds to subwoofers which are better designed to handle them, you're reducing that distortion.

3. Amplifier capability: Distortion increases as you increase an amplifier's output toward its maximum. Most of an amplifier's power is needed to drive woofers at low frequencies. By offloading the lowest frequencies from the amps used for the mains and surrounds to the amps in the subwoofers, you're reducing that distortion, too, as well as making more headroom available.

Yup! Some people consider this an enjoyable part of the audio hobby. Not all do. (I'm actually more toward the latter end of the spectrum.)

D+M AVRs and pre/pros support using separate connections for separate sets of A and B main speakers. Using that feature does reduce the options available for the main surround-sound configuration, though.

And, of course, if you decide that you don't like how Audyssey works in your room, you can easily disable it.

I hope these comments help a little.

When you talk about over lapping bass, my speakers are 80hz and lpf is 120. Is this ok?

Yes, it is OK.

The LFE LPF provided in modern AVRs is used only for the LFE channel (the channel designated as .1) as it comes off the disc. It does not affect the sounds sent to or coming from the other speaker channels. The on-disc LFE channel is allowed to contain frequencies up to 120Hz. However, a few people have found that they like the sound of the LFE channel better if they reduce its LPF to 80Hz. Remember that filters are not "brick walls". They have a "slope" and do allow some higher frequencies through. (Also, the LFE channels on a few Blu-rays have been reported to contain unintended noise at frequencies above 120Hz because the mixer forgot to engage the LFE filter in the mixing software. While lossy multichannel endoders cannot physically include frequencies above 120Hz in their LFE channel, the lossless encoders can provide full-frequency bandwidth in all channels, including LFE.)


Overlapping bass happens when you send full-range signals to the main speakers, but replicate their lowest frequencies in the subwoofer(s) (i.e. turn on LFE+MAIN). Before the advent of receivers which included bass management, that was the only option available. The low pass filter on the subwoofer itself had to be carefully adjusted so that the subwoofer's high frequency sounds would blend in with the low frequency sounds coming from the main speakers.

Sorry, I can't help much with bi-amping. I've never used it.

However, by picking the amp assignment "zone 2 5.1 bi amp", you have explicitly enabled the separate zone 2 in addition to the bi-amping. The zone 2 amps and preamps (and a lot of the receiver's shared circuitry) are on until you turn them off as you did.

If you want to keep it simple for a bi-amped 5.1 speaker configuration (and are not using Atmos), you can select the amp assignment "7.1 channel (Bi-Amp)". Then when you run the calibration it will turn off the speakers that you don't have.

Otherwise, you need to select the 11.1 amp assignment and do the settings manually.

So its ok to choose 5.1 bi amp and zone 2 and just turn off zone 2?

Audyssey's calibration is done at 75dB. It doesn't matter what level is used for a calibration, so long as it's consistent. 75dB is quiet enough that it doesn't bother most people, and its individual calibration pulses are brief.

There are several reasons for choosing a crossover frequency of 80 Hz, which you might want to consider. Some are related directly to sound quality, others more to electronic capabilities.

1. Room modes: Low frequencies interact with your room's dimensions, resulting in peaks and nulls in sound levels at various locations and frequencies, potentially up to about 200 Hz depending on the size of the room. This is quite unlike how higher frequencies interact with the room's surfaces. You have to place subwoofers so they produce the flattest response at your main listening position. The optimal locations for subwoofers usually are not the same as the optimal locations for your main speakers.

2. Speaker capability: Distortion increases as you push speakers to the limits of their frequency performance. By offloading the lowest frequencies from the mains and surrounds to subwoofers which are better designed to handle them, you're reducing that distortion.

3. Amplifier capability: Distortion increases as you increase an amplifier's output toward its maximum. Most of an amplifier's power is needed to drive woofers at low frequencies. By offloading the lowest frequencies from the amps used for the mains and surrounds to the amps in the subwoofers, you're reducing that distortion, too, as well as making more headroom available.

Yup! Some people consider this an enjoyable part of the audio hobby. Not all do. (I'm actually more toward the latter end of the spectrum.) D+M AVRs and pre/pros support using separate connections for separate sets of A and B main speakers. Using that feature does reduce the options available for the main surround-sound configuration, though.

And, of course, if you decide that you don't like how Audyssey works in your room, you can easily disable it.

I hope these comments help a little.
Selden , my main speaker`s fall off low frequency is 35hz and the subs are set at 42hz ( not 47hz , as I said previously . I didn`t seem right , so I visually checked to be sure and yes , the filter pass are set at 42Hz , my apologies) .
The subs interlap the mains low frequencies perfectly ... no bloated bass here , I can assure you .
I will read the Audyssey thread , for sure.
BTW , the subwoofer setting for the Denon`s 5803 is set at 40hz variable .
And yes, I think that 75 DB cut be acceptable .

Audyssey systems on two different Denon models (4310 and x4000) each wanted to set my center channel and surrounds as LARGE. These are not full-range speakers in any sense of the word. Maybe they can output some low bass, but it's going to be much more distorted than the low bass output of my two subwoofers. Similarly, my front mains (B&W 704) are good down to about 30 Hz and they make some sound below that point (using test tones on a CD to check this), but I get much more bass impact by setting them to SMALL. I use 80 Hz all around as a crossover. I tried 60 Hz for the front mains and didn't hear any real difference between that and 80 Hz.

Hopefully someone can enlighten me on something. Just got a Marantz NR1504, which is my first AVR with Audyssey or anything like it. Ran the setup, did six positions, and everything seems to sound great except the sub. No matter where I set the output level on the sub (other than basically almost off, -6db or even lower (no markings that far down on dial)) audyssey sets it at -12db. Its an older M&K MX-125 Mark II, which by todays standards should be pretty tame, but am I being told by the program that its too much for my room? At this point its barely audible. Room is roughly 12x15 standard living room. Sub is in the corner but not too close to either wall.

Thanks in advance!

I agree. No matter how low the main speakers go, they will always struggle to reproduce very low frequencies, very loudly, compared with a good purpose-designed sub. Very low, very loud sounds demand huge amounts of amplifier power, which may or may not be readily available via the AVR amps. This in turn can affect the higher frequencies which may be starved off power on loud bass peaks. And it is also a huge ask of a regular speaker too to make loud 20Hz sounds, again stressing the speaker unneccessarily. If you have a sub, use it. That's what it was bought for. And low bass, loud, is what it does best.

You need to set the sub's physical gain knob lower so that Audyssey sets the trim higher. At -12dB you have maxed out the trim.

See here:

f)3. How do I set the controls on my subwoofer before running MultEQ?

f)4. If I want to run my subs a little 'hot' where should I make the changes?

f)5. Since I ran Audyssey everything sounds great - but where has my bass gone?

Yes, 100% correct. That is why I set my two Gravis subs at 42hz . They overlap my front main speakers , that can go down to 35hz , but would need to be cranked real loud for that , while the subs can take over from 42hz down to 24hz effortlessly and at normal sound levels . The trick , as Selden pointed out previoulosly , is the overlapping frequencies . If you do it right , the result is incredible accurate bass .
Of course , I am referring to music .

Thanks, and I will read through that stuff before running another test, its just that the sub is literally turned down all the way and i'm still getting the -12. Could the fact that its a 'push-pull' design have anything to do with it? I read it can cause issues with what audyssey determines as the distance.

Thanks
