My room is roughly 20x20 and the speakers will be used almost only for gaming and home theater.

I'm sure I will listen to music from time to time. I listen to a wide variety of music - from classical and opera to funk, industrial, punk and rock/metal.

Sounds like I will need to go with the CP150 center because I cannot imagine where I would stand the M22 upright - and I don't think 2 M22s end-to-end would be cost effective (also how would you wire that? split the signal?).

Would the M22s sound to 'small' in a 400 sq ft room? The speakers will be roughly 12 feet from the viewing/listening position.

Thanks again guys
