I have a 3700 cubic foot room I will be placing a home theater system in. I am just about sold on the Axiom product, pending a test drive, but need advice if the M80 package with the 500 sub is too much for this size room? Also I noticed the M80's are 4 ohm...I don't really know what this means, but have a budget of 3500.00 for the amp/receiver. If these speakers are ok in this room , maybe the 60's are best, what is the minimum amps needed to drive the system and what products do you like best. I have seen B & K, Denon, and Pioneer....becoming a blur.

HELP!
