I currently use Infinity RS-3's in front with an Infinity CC3 center. I use Infinity QPS-1 surrounds. How well does the Infinity OWS-1 match up with the old QPS-1 for the rears on a 7.1 system? Or does it really matter. I would like to mount two rear (white) speakers as the QPS-1's are white. Just bought a Pioneer VSX-1014TX receiver last night. Also have a JBL E-250P subwoofer.
