To Doug Schneider,

Whenever I play bass-heavy music, I hear a scratching sound in one woofer, as if metal is scraping. I don’t have to play it loud to make it happen. Do you have any idea what it is?

Robert Regan

Yes, I had a similar thing happen with bass-heavy music with one of my speakers that I owned about 25 years ago. One track that I could always play and hear it with was “Fallen Angel” from Robbie Robertson’s self-titled 1987 release. That track opens with very deep bass and little else, so it's easy to isolate the problem. Your description mirrors what I heard -- a metal-on-metal scraping sound. The technician I took it to thought it was the woofer's voice coil scraping against the magnet. The company replaced the driver and the problem was fixed. . . . Doug Schneider
