Your right WhatFurrer its SVS PB10 NOT SB10. I was at work typing this up and was in rush. I don't know where I got the SB from. (I wouder if SVS would rename there sub too SVS SB10?)
Now about the "breaking in new speaker" part. Is there any truth to that? Or was it that my ears were breaking in? I just know that when I first tried the speakers, I couldn't handle that so call bright sound.
