I have the M22/VP100/QS8 combo in a 12x20 ft room. The VP100 will do fine, as a matter of fact when I received mine I was practically startled with the way it sounded. Of course, all my Axioms are startling good. I've never felt the need to upgrade the center channel. I ordered my QS8s in light maple since it matches the color of the walls so closely. I used the t-brackets that came with them to wall mount them. The camouflage worked pretty well. No one notices they are even there until they hear them, but some do wonder where that sound is coming from.
