very good idea the sub must be exactly the same as my first sub? if I want to put it at the back, diagonally from the first?

very good idea the sub must be exactly the same as my first sub? if I want to put it at the back, diagonally from the first?
I have exactly the same experience and using the support function Dynamic EQ seems stupid to me.
Absolutely. Last weekend I tried Audyssey on the stereo result was tragic. Basically, it completely removed the dynamics and naturalness, I had no problem in the stereo, I just tried it, because everyone here praised it in the stereo as well. So I deactivated it for the cinema and the result is excellent. Apparently I don't have a problem with the room. In addition, almost everyone here prefers to limit large speakers to 80Hz. I reset it to full and now I'm really happy. Audyssey can really help someone, a lot of advice is meant well but we don't have the same rooms or equipment.
If we think about it logically, after the calibration of Audyssey, the Dynamic EQ function will be turned on automatically. Apparently he knows about this problem, or it's something for something. And a lot of people don't care, you just add db to the subwoofer that beats everything. I started the calibration, had Audyssey adjust everything, and then Audyssey turned off.

May I know how many microphone points you used when doing the room eq process? Where did you place the microphone?
At least in my rooms, using too few points hurts the sound quality. Try using the max available points and especially make sure you have back and forth variations.
I used all eight points. After eight months of using the SR8015 with Audyssey, I will never return to Audyssey. Again, Audyssey can help someone.
Not heard that Audyssey complaint before about "reduced dynamics". It does aim for a flat response, which you may or may not like. DynamicEQ is a loudness contour changing with volume below reference level....whether you find that useful at lower volume or not, YMMV.

Hmm....
Maybe it is room modes for your sub. Audyssey maybe trying to tone down the bass peaks too much for your sub and set the sub volume too low.
Did you have a chance to measure your sub freq range using REW? There could be a strong peak in certain freq that maybe a minidsp could solve.
I would say yes, because according to Denon Canada:
AVR-X3700H (denon.com)
The ONECALL link did not work for me, but the eXpro and ListneUp did and was for $1,299, in stock..
The biggest problem is that all Audyssey microphones can be considered broken because they are not calibrated. The cheapest calibrated microphone with a 3.5mm jack is the Dayton iMM-6 that I have. It has a serial number and I have to download a calibration file that corrects the frequency response in the range of -3.9db to + 2.3db. What tolerance does the Audyssey microphone have? Who knows and where it is written? Audyssey microphones are made as fast as croissants and are not controlled by anyone. Although I have Marantz and Audyssey, I consider Audyssey to be broken just because of the microphone.
Good to know. I'm torn between this AVR and the new models, even the higher end ones from Onkyo. Who knows if Onkyo will adopt the preamp disconnect feature...
I don't know, but in the past Onkyo, like Denon, only have preamp mode for their flag ship models and as far as I can remember they don't have the front left/right channel disconnect feature.
According to Audyssey, the mics are specifically calibrated for the job.
So you're just prejudiced? Okay....
ps How do you consistently position that mic plugged into a phone?

Ideally, yes you would want it the same. The reason is that you want the roll off at low frequencies to match. If not, the subs will be out of phase at some point, which will, not might, will, cause cancellation. This results in *less* bass with two subs in the area where they are out of phase, then what you get from one sub. Since we pay the most $$$ for low frequencies(which requires larger drivers, more excursion, more power, larger cab which all = cost), I don't think it is wise to mix match subs and reduce SPL capability in the low frequencies.
This is a general rule of thumb and, IMO, applies in the very low frequencies where subs will mutually couple regardless of where you place them in the room.
Now, if two very similar subs have very similar low frequency extension and matching roll off frequencies and slopes, mismatch in phase won't be an issue and they should integrate fine.
So, if your single sub is really good and you are happy with it, add another IMO. On the other hand, if the single sub is a weak link, or doesn't have the extension or output or sound quality you prefer, I'd consider selling or repurposing and adding two matching subs.

I've seen the Audyssey mic tested compared to calibrated mics, and they perform surprisingly well with better than expected correlation. What objective data do you have showing the Audyssey mics are so bad that they are "broken"? Or is this just your assumption?
Where are the measurements? If I have time this weekend, I will perform measurements with the Dayton iMM-6, including a calibration file against the Audyssey microphone.

It was an old thread on AVS forums. The images may not be working. When I went to find the thread in order to link, (almost)none of the images showing response comparisons are working, but maybe its just me. Here's the link in case anyone is able to see the images:
