This problem involves my Harman Kardon AVR 525. For some unknown reason when random bass notes occur within Dolby EX broadcasts the resulting sound is akin to grinding rocks. This terrible noise is heard in all speakers. The audio cable has been tested and eliminated.

Your comments and suggestions are eagerly awaited.

Louis,

it sounds as if you might be experiencing clipping, which happens when an amplifier is overdriven. Clipping can destroy your speakers (esp. the tweeters).

Until you have remedied the problem (either by less demanding speakers or higher powered amps), DO NOT under any circumstances continue to play your system at the volume level you have been using.
