Blown R300's

[GeoNewf]

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?

Actually a lower rating receiver/amp than your speakers can also be harmfull to your speakers if you crank it pretty loud as distortion peaks are sometime generated and can easily blow your speaker drivers (typically damage will in fact occur in the higher range thus the blown tweeter rather than woofer).

BTW, welcome to Club Polk...

Thanks for your reply Technokid. I realize that distortion can blow the tweeters, that's why I had the volume on the receiver limited to 0db. The R300's were set to small in the receiver setup & the bass output to the Klipsch sub.

I dropped the R300's off @ a local service center today. The Polk Canada rep recommended this. So I guess in a few days I'll know if Polk is gonna cover the damage.

Thanks,
