I just purchased a Yamaha RX-V673 A/V receiver, a pair of PSB G1 speakers, and a set of anticable speaker wires, for a stereo set-up. The problem I am having is that the sound does not come out sounding particularly "full". I have a feeling that it may have something to do with the bass. Could it have something to do with the bass cross over? I don't even know if that plays a role in a stereo set-up. Right now I have it set at 80hz. What would make the bass sound "fuller" raising or lowering it. Is it even disable with my speakers? I did the YPAO automatic set-up and played with various settings to no avail. My speaker stats are below if that helps. Any advice on enhancing my sound would be greatly appreciated.
