I just purchased a new setup, and I am very new to home theaters.
What I have is a Harman Kardon AVR 254 running 7.1, with monitor 70s in the front, 60s for the sides, and 30s for the rear. I have a CSi25 for the center and a PSW10 for the sub. Maybe I went a little overboard on the speakers and the amp can't keep up with them, but it seems like it's really QUIET. I can nearly max out the volume and it's still not that loud. I would have figured it would be extremely loud near the peak volume... I also don't know how to get use out of the side and rear speakers without using stereo mode.. makes me feel stupid for getting 60s for the sides.
But yeah I don't know a ton about this stuff, so it would be nice if you guys could analyze my setup and let me know what you think I could do.
