Hi guys, I'm a little confused here & hope someone can explain this to me. I have 2 R300 speakers that recently blew. They are hooked up to a Denon AVR-590 receiver, a Klipsch RPW-10 subwoofer & a PS3. The main speakers are set to small. I was listening to a CD the other night & turned the volume up to -5db. A short while later I heard some popping & the right speaker went silent. The circuit protection on the receiver kicked in & shut down power to the speakers. I reset the receiver & turned down the volume, the speaker was still dead so I swapped the left & right Speakers. Same speaker was still dead. Removed the drivers & tweeters & tested with a meter. Found that I had blown both tweeters & 1 driver. This receiver pumps out 75 watts & the speakers are rated for 100 watts. So I guess my question is, how is this possible?
