I would suggeest looking into Velodyne's new DD series. Very tight control of the bass and fast response. Add the benefit of equalizing the room modes and nulls with teh built in equalizer and provided video output/remote/microphone and I don't think you can get any better at that price.
I have a DD12 in a very small room and love it. Flat response from 125hz to 15hz.
