My HT was set up in a 19' x 23' x 8' room laid out width-wise with M80's, VP150, 4 - QS8's, and an EP500. There was enough bass, but it wasn't even enough, so a second EP500 was really called for for that size room. Some here would probably argue that 4 subs would be best. The center channel was the weak link in my setup but it was the biggest Axiom carried at the time.
I've already traded in the VP150 and will get a VP160 or 180 (or whatever is the latest and greatest when I order) when I finish the basement here. I will probably get a second sub, too, even though the new HT room will only be 20 x 14.5 laid out length-wise.
