Also, gonk, I tried the crossover settings you recommended for my Axiom speakers (60 for the mains, 100 for the center, and 120 for the surrounds) and man does it sound great. The difference is most evident in the M80's. I forgot just how much these speakers can handle and now that I lowered the crossover frequency, they really shine. I was listening to some music in stereo mode last night and I fell in love with my system all over again.
