speaker/room interaction question

Hey all,

I recently moved and my new listening room is giving me a huge pain in the @$$. The room is about 9'x21'. From the centerpoint of each speaker, they are about 95" apart. The room was converted from half of a garage and the walls are stained plywood. It looks a lot nicer than I'm making it sound. I've deadened it fairly well with whatever blankets and sleeping bags I can find along the walls and corners etc... It has helped and there are no obvious echos when I walk around the room and clap. There is still a very unfortunate resonance in the lower midrange. When I say resonance, I mean the tone becomes muffled and distorted. I'd say around the low end of a typical male tenor vocal range. It doesn't happen when only one speaker is playing and it doesn't happen when the speakers are out of phase (discovered purely by accident). I've moved the speakers all around the room trying to get rid of the resonance. So far it seems to be independant of room orientation. I only had the speakers a short time before I moved, but I'm pretty sure I would have noticed this in the previous environment.

I greatly appreciate any thoughts about getting rid of that pesky resonance.

FYI:
Speakers are GR Research AV2
Stands are DIY- sturdy and sand filled on spikes
Resonance is independant of music source (i.e. record or cd)
floor is carpet on concrete


Its not how many people you shoot ... its who you shoot
