Thank you for your resonse. I have the RPW-10 subwoofer. It was a all in one package except for the RSX-4's which are my main fronts and the RSX- 3's for my center and rear surrounds and rear 7.1 spkrs.Since I am very new at this what would you suggest to set them as? Small for all 7 of them? It is a relativly small room about 10X11 and all speakers are wall mounted. The mains seem to dominate all the sound. Any suggestions for me?
