I am in the prcess of building a dedicated HT room in my basement. I cuurently have 2 RB75's, 1 RC7, 2 RS25 in which I will be replacing with RS52's. The sub that in using now is a Synergy SW12. The room will be 11 x 19 and the projector will be a Sony VW50 1080P projector with a Steward 96 screen. My current equipment is a Sony KP-57HW40 Rear Projection TV, Denon 2802, Sony SATHD200 receiver, Sony C222ES 5-disk SACD player. Sony DVP-NS700P DVD Player and Mushubishi HS-U778 VCR player. Theonly thing moving to the basement room is the speakers and CD player. I will be purchasing a Pioneer VSX82TX receiver, Pioneer BDPHD1 blu-ray DVD player. Im not sure what sub will work best in this setup. I did have my eye on the Klipsch RW12D.
