So, I've given my friend my old set of large bose floor speakers, my paradigm CC-170 and a passive subwoofer. I'm even trying to give him my PA-120 but I think his wife is resisting arrest on that. LOL. So, for setup using a Pioneer VSX 520 K and only a 3.1 setup, what settings should I have him use? Should I just use the stereo sound and forget the center speaker? Would using the dolby digital sound without the rear speakers cause him to miss and loose part of the sound?
