His room eats bass around ~20hz, maybe widely above and below (16hz shakes his screen wall something terrible. It is one of the toughest bass/acoustic spaces I have encountered (fireplace, open stairwell with not real door at top, not sturdiest of walls, not any absoption...)The submersive dug so much lower than the rest, it is possible that it extends beyond a room resonance? Once the walls start moving, they start eating. If volume turned up at room resonance, just as Jeff stated the wall moves more and acts like an out of phase speaker. This is like turning up the volume on two subs that are out of phase, nothing much happens. Also Counsil was right beside the rooms biggest null (center). I am not up to snuff of how exactly these nulls work at differing outputs, but is it a possiblity that the null expands in size when it has a huge amount of cancelation going on there?
I will update my findings and testings with omnimic over at Carp's when we get that all setup and going. His SMS is in the mail, and he is pretty busy this time of the year and I have been pretty busy myself. Might be before memorial day weekend, maybe not.
