So, I have some questions about safely integrating an amp with my new b &w m-1 speakers. I have an SVS pb-1000 sub (19hz-270hz +-3db) and just bought M1's (64hz-23khz +-3db) to go with a pioneer 1222k. It's a 5.1 setup with the mains and surrounds wall mounted and the center sitting in front of my plasma on top of a fireplace. I needed a speaker that could give me more lower midrange without taking up space. Anyway, I am running the speakers at a 100hz crossover in a rather large room (over 4000 cubic feet). My question involves the wattages of the speakers and the amp. The 1222 is capable of 120 WPC at 8 ohms and higher at 6 or 4 ohms. The speakers are rated for 20-100 watts with a nominal impedance of 8 ohms and a minimum of 4 ohms. They also have a sensitivity rating of 85db. I currently set the pioneer receiver to stop at a volume max of -10db, so it can't go any lower than that. I haven't noticed any distortion or anything at -20db (that's the loudest I've gone), but my question is do you guys think that I have this system set up okay to avoid speaker distortion or damage? I don't really think I would even go down to -10db, but should I set the limit to -20db to be safe? The problem is weaker sources may need more, and -20db might not be enough.
