Here was my response to SVS...
Large isn't enough. It still leaves just enough heavy boosting in the teen hz area that the subs are unhappy at reasonable volumes (-20 from reference). Medium neuters the 20hz to 35hz area too much for my taste. I just want to turn around and up the sub trim level which reintroduces the popping.
I have been posting on the SVS Ultra thread and the Audyssey thread regarding my findings. At first Audyssey totally denied that this could ever occur. Now multiple people are stating that it is happening to them as well, and they are frustrated just as I am. Audyssey says that they cannot reproduce this issue with their Denon 3808 and SVS Ultra. I can reproduce it all day long. With the 15hz and 20hz tunes, and with 4 acceptable sub locations in my basement.
I believe enough people have spoken up that Audyssey is taking note. However, I had to get frustrated and a little rude before people started piping up. I do not like to be called a liar, especially when I have REW graphs to prove that Audyssey alone, not just Dyn EQ, is boosting the teen hz area by more than the 9db max. In my opinion a 9db boost is crazy at the natural rolloff of any sub. That is like asking someone to sing 9 notes lower when they have already sung as low as they can go. A simple comparsion, but true nonetheless.
One of these days I will get everything figured out. Until then, please bear with me
