Question Sudden buzz from subwoofer

[kjwray]

Hi all:

Not sure if if my sub is about to croak, but while playing music, it occasionally emits this harsh buzzzzzz for about a second or two. Other than this strange behavior, it sounds and works fine.

Connected directly to my receiver with a RCA monster cable.

Never had a problem with background hum or ground loop issues I’ve seen described on this forum.

Any ideas are appreciated!

Hum due to a ground loop wouldn't come and go. My guess would be either the cable (try another one) or that the sub amp may be on it's way out.
