Hi, can anyone please help me as I am new to this home theater stuff. Just bought speaker and a reciever. SB-3 SS-1 SC-1. Klipsch all 100W speaker Yamaha 5660 85W per channel. When watching a movie last night there was an explosion and I heard popping noises from the speaker. The explosion was in the movie not my house! Why did this happen? I turned down the volume and it did not happen again. The volume was not really that high the first time when it did happen thought. Is this clipping and if so why did 100W speakers clip with only a 85W amp? Any suggestions on how to fix this?
