I recently picked up the CSi40 at CC for only $169 open box, and, I have to say, it's a tremendous improvement over the CSi30. I'm wondering, is it ok to set it, and the RTi38's to "large"? I know everything is supposed to be set to "small", but I let a friend have my old Sony subwoofer. I usually listen to movies at a low to medium sound level(apartments suck). Will setting the speakers to "large" damage them in any way?
