The header says it all. I've currently got a Mirage MCC-R center channel speaker that I'm using with a pair of Audiosphere Research fronts and Axiom QS4 rears.It's mismatched I suppose, but the system sounds *amazing*. At the same time, as I get ready to move into my first house (!), I'm considering getting a pair of M80's for my new home theater room, which will be in a basement 12x20 with 7 foot ceilings. Should I worry about the Axioms "outing" the Mirage center as far as even soundstaging goes? Also, would the M80's be okay in a room this size?
