I just finished all my purchasing. I am very happy with my setup EXCEPT the PSW505. Its a HT in a 13x14 foot room 8 feet tall. The back end of the room is open (where i sit). I am running a Pioneer VSX-1015TX reciever with RTi8, FXi3, RTi4, CSi5 and the PSW505. The rest of the system rocks. Loud, clean, awsome. I want the base to BEAT ME UP. Please recommend a solid sub that will go LOW and LOUD... that is what i want to make me happy :) :) :) !! My older PSW350 sounds just as good as the 505!! Dont get me wrong, it great for the money, but i want to shatter windows. THANKS IN ADVANCE FROM A NEW POLK FAN!!!
