Thanks, Alan! My room dimensions will be 10.5'W x 7'H x 24'L. I don't like insane levels of volume, but will want to shake the room from time to time. Actually, my wife likes to listen lots louder than I do. Given that, are the M80s complete overkill? Also, would an EP500 or 600 be overkill for that room?

A question on the H/K receivers. It seems that their wattage output levels seem much, much lower at any given price point than other brands. Would a 65w or 75W H/K drive the M80's?
