I'm glad to hear your enjoying your Axioms. I find it hard to believe your EP500 is WAY to big for your room, are you sure you don't have it running to "hot" (gain to high)?

Your room is almost 7,000 Cubic Ft, mine is 8,000 (30 x 31 x 9). I've owned the 350, 500, and now the 600 and the 500 and 600 are great for larger rooms.

I'm wondering if you just have it calibrated wrong?
