Ok, well I hooked them up and played some 2 channel music (Yoshimi Battles the Pink Robots \:\) )through them. The max volume I turned it up to I read about 83 dB on my SPL meter. Didn't hear anything out of the ordinary. I'm going to try some 5.1. I figure that will put a bigger strain on my receiver? Is clipping something that will happen right away or does the strain on the receiver build up over time?
