The subs are not equidistant. I totally expect different results, hopefully more uniform distribution over the listening area.
I am taking measurements in all iterations. Will post the results here when ready.

Putting some vibration absorber underneath sub can decrease coupling to a supported wood floor that leads to unwanted vibrations in the floor. These can affect audyssey measurements.

46dB isn't an unusual level of background noise for a home. A library is reckoned to be about 40dB and a normal speaking voice about 60dB, so 46dB isn’t anything to worry about. It certainly won’t be an issue for Audyssey. What made you think it might be a problem of some sort?

You may be surprised at how much very low frequency noise is present, and most of it is almost inaudible to us, or our ears/brain just ignore it. Try taking some background measurements during the night and see how much lower the figures go. I have seen differences of over 10dB on my SPL meter between afternoon and past midnight.
Also try turning everything off, and if that makes a difference, then investigate what was the culprit.
Regards, Mike.

Hi Mike and Keith

Thank you it was not so much as i thought it an issue just that i was amazed that background noise was so high i guess if a library is in the order of 40db mine is nothing odd lol

Thanks again as i say it was really a shock that when i could here nothing that 46db was present

It will be lower at night as Mike says, but for the purposes of running Audyssey etc it can be ignored. If Audyssey detects the ambient noise is too high it tells you, raises the level of the chirps and tries again:

2. Why does Audyssey report ‘Ambient Noise Too High’ when I am running the calibration? (click here)

FWIW I live deep in the English countryside, miles away from any main roads and so on and the reading on my meter at the moment, in my study, is 59dB. I’d expect it to drop by as much as 10dB towards midnight. I'd say your room is exceptionally quiet, or very well insulated, at 46dB.

Hopefully this isn't a stupid question, so...

I looking at getting a new reciever to replace my 11-year-ish Kenwood VR-4700. The new recevier I'm looking at has MultEQXT32. I'm also looking at doing a DIY subwoofer to help keep my cost down. Most of the amps I'm looking at for the sub only have adjustments for gain and crossover, so no EQ adjustments.

So my question is, do I even need any EQ at the sub? XT32 will handle this for me?

New at this subwoofer implementation stuff, so thanks!

Yes, you need MultiEQ XT32 in most situations to get the most out of your sub. It does a lot to even out and tighten up your bass response (although it will not cure nulls that are due to poor placement of the sub or the geometry of your room). As an example, I have an M&K sealed sub in a 12x13 room. I am using an SVS AS-EQ1, which does exactly the same thing with a subwoofer as XT32 does. With this device, I get noticeably tighter bass that is better integrated with my other speakers. The rest of my system is room corrected with a receiver that has MultiEQ XT, which lacks the resolution of XT32. Turning off the SVS unit and leaving the MultiEQ on, the decline in sound quality is obvious--music is muddier, special effects involving bass an midbass have a more diffused kind of impact. If I were receiver-shopping today, I would definitely want a receiver with MultiEQ XT32.

You don't need any additional controls in the sub - XT32 is terrific at sorting out the sub all on its own.

Thee is a whole forum for DIY speakers and subs, and you should ask about EQ for your sub build there. Short answer is it depends. What driver, what size box, is it ported, what are your SPL and frequency response goals, what's your room size, etc.

You can put a speaker inside a box and conect an amp and end up with a frequency response that peaks at 80 Hz and falls off rapidly above and below that. Depending on your room, you may find that your low end extenision is inadequate, and Audyssey won't correct it much below the -3dB point (which theoretically could be as high as say 60 Hz in my example, leaving out two octaves of bass . . .)

If none of this makes any sense to you, roll around in the DIY forums and see if you can get a feel for whether you want to learn how to build a sub that does what you want it to do.

With JHaz's cautions in mind, for practical purposes you do not need any EQ within a well-designed sub's electronics as XT32 will handle it very well. The std recommendation is to turn off commercially-produced sub EQ.

You can only do that with Audyssey Pro (which requires the Pro kit and license.)

Pro kit ~550, license 150.

Even though you have the pro kit, its not as if you can switch easily between stored Audyssey presets. You have to start the computer, find the measurement file which the software has to process, find the target curve file and upload it all to the processor. So not a doable method if you want two presets for different seats for example.

It is doable, just not quick and convenient. I have two sets of surrounds - one for multichannel music and one for everything else - that I manually swap connections at the wall plates.

Stepping to the screen to load the measurement file doesn't take that long, nor does loading it. There is calculation time, a little more time to load the customized target curve and then more calculation time. And then that needs to be loaded into the processor.

Overall I'd estimate it all takes fifteen minutes.

I have had a look at the link as well and i admit my reading was held in my hand not on a tripod so maybe this is part of my what is a lower result lol me thinking i was high.

The house was is a 30 year old build but has good sound proofing and as part of my acoustic work i have really gone to town on holes cracks etc.

Many thanks

Of course its doable in some way, but I'm just saying that if one thinks that buying the pro kit lets you switch back and forth between target curve and measurements, they will be disappointed. Its not just a preset solution.

You can't. But you can store one calibration - see the FAQ here:

I do not see in the FAQ where it mentions you must have pro to do this ,Do I need pro to store a calibration or can I do it with normal xt32, A simple yes or no will work Thanks.

The answer they linked you to is in the FAQ for the consumer version of Audyssey and the storage method described is therefore how to store a calibration with the consumer version of Audyssey. So that would mean that you do not need Pro to store a calibration.

You're welcome.

A simple Yes or No will not work because the answer is No to one and Yes to the other part of your question.

The FAQ response I pointed you to shows how you can store one calibration with XT32. Pro kit users can store as many calibrations as they have room for on their PC.

I suggest you read the FAQ response again. It applies to XT32. It does not mention Pro in the FAQ because the FAQ is for MultEQ not MultEQ Pro.

^I will add the following comments which I submit for consideration to be addied to the Denon portion of the FAQ
"a)6. Is it possible to save and recall an Audyssey MultEQ calibration?" which is under discussion.

The Denon Network Save/Load feature allows you to Save entire Audyssey calibrations (along with all the other custom settings you have done in the processor) onto a networked computer HD. Save takes under 10 minutes. You can save as many different calibrations, individually labelling them as as you like. A subsequent Load of any of these files takes under 10 minutes. This works regardless of XT, XT32, and it works even if you used a Pro kit to generate the calibration.

It is considerably faster and easier than using Pro by itself to perform this function, because within Pro, you have to call up a saved Pro mic measurement data file, recalculate the filters and reload the calibration into the processor.

(Again, kudos, the FAQ is excellent!)

SoM - thanks. I have zero knowledge of Denon AVRs and prepros, so rely on others to tell me where they differ from Onkyos. That feature sounds fantastic. Would you care to draft some appropriate wording to get across the point and I will add it to the FAQ? Thanks.

Thanks again, I have been making some progress with my calibrations. I shut off my fire place pilot light, it was alway sputering quite loudly and it is right behind the MLP. I am now hearing improvements but still want to test more.

Others please feel free to correct/comment. Here's my suggestion:

For Denon CI networking models only, follow this procedure:

Use the Web Control feature to SAVE the config.dat file. onto a networked computer HD. This file includes the Audyssey calibration, any modifications you've made to it and all other custom settings in the processor at that time. You can later LOAD the file to the AVR restoring everything as it was. You can save as many different calibrations as you like, individually labelling them. Each Save or Load takes under 10 minutes. This works regardless of XT, XT32, and even if you used a Pro kit to generate the calibration.


For Audyssey Pro Installer-ready processors of any make:
with the use of the Audyssey Pro Installer Kit you can (and should) save your mic measurement raw data file (as many files as you like, actually) on your PC. Rather than redoing an entire Pro calibration, you can call up that mic data file and use it to generate a new Audyseey Pro calibration at any time. For ex., to change the satellite crossovers, or to create a custom curve, you simply call up a saved mic data file, calculate the filters in Pro and load them into the processor. See the Pro Installer kit thread for more info.

If only this worked reliably and consistently for everyone. My Denon 4310 downloads files with actual data in them (not zeroes), but the upload has always failed.

What is the best lowpass setting for a ext sub power amp. I'm using a Crown xls1000 in bridge mode. The DSP range from 50hz to 3Khz. My avr LPF @120 and all the speakers @80hz. In auto setup, what is the subs upper test range limit ? Some say about 300hz, is that right if so should I set the xls1000 DSP to 300hz ? I've listened with the DSP set as low as 50hz, to 500hz they all sound good, the lower 50 to 80 sounds clear and powerful, but with a thud or thumpy.. Above 80hz The sub sounds fuller, but hollow at times. By the book what would Audyssey say to set the AMPs LPF, this is a full range amp, not a limited range sub amp. I was thinking 200hz cause that is the Xover max for all speaker settings in my avrs menu...

AFAIK there is really no reason to engage a low pass on an amp receiving a low passed signal. You'd want to keep the amp's low pass out of the way of the crossover, so say at least 2 octaves above the crossover point. But the amp's low pass would just be turning down frequencies above it's setting, and no such frequencies are reaching the amp because the crossover's rolling them off, hence there's nothing to turn down, making the issue a bit of a tempest in a teapot.
