I am building a system around some Klipsch RF 52II's. My room is 14x19 with a 13' ceiling (about 3500 cuft). It is somewhat open concept. The room is carpet over a slab floor. It will mostly be used for TV/movies and some music. I am considering Def Tec ProSub 800, klipsch SW 110, Klipsch R 10SW, Polk DSW 440, and Sunfire SDS 8.
