I think I've solved the problem. Believe it or not, the problem seems to have been the positioning of the speakers. Previously, I did not have the speakers at exactly the same distance from the listener, due to some obstructions in the room. I managed to remove the obstructions today and position the speakers evenly, and now they sound awesome. I'm so glad I went with Axioms. One question: how loud can I safely play the speakers, without blowing anything?
Thanks,
