Hello everyone; I just joined this forum and this is my first post. I have an older Pioneer VSX-D814 receiver, 2 Sharp tower speakers (CR4800 w/ 10" woofer, 5" midrange, and 3" tweeter), and a KLH E-1208 120 watt powered subwoofer. I recently won a 46" RCA "1080p" flatscreen TV. I am trying to set up 7.1 system (on the cheap for now), but need some input on surround speakers. I have been looking at buying 4 Polk "Monitor 30 series bookshelf speakers for my L R surround and L R rear surround. My living room is 15' x 17' and prime seating position is about 10' away. Would these provide good surround sound for DVD and TV? Any input would be greatly appreciated.
