Good ideas, maybe a sport type carpeting like you see outdoors, to help with the floor. I already told them it would be easy to take some 2 x 4 owens corning rigid fiberglass like I used in my panels, rap them in college/pro color fabric and even put team logos or whatever on them. Placed on the wall strategicaly that might really help.
I just know that he was originally looking at a Klipsh 5.1 small system for like $550 at bestbuy. Might be hard to sell even the m22's, might have to go with m3's.
