I made sure the receiver was off and actually I unplugged it from the wall. I think I will switch it back. I tried it even in stereo mode and they still dont sound like they used to. Seem like I have to turn the receiver up more to get the same volume, and if it was not for my ksw-12 I would have no bass. I did not realize how weak of a bass response these speakers have. I almost wish I had of kept my synergy ksb 3.1's they seem to have more kick to them on stands.
