Hi,
What would cause a low end humming noise (low rumble) [only sometimes] in the bass section of this speaker? Tried turning down the bass, running power thru a surge suppressor, a different outlet not close to my other a/v equipment, etc.
Running def tech BP7002 as the fronts & Marantz SR5010 receiver.


Any suggestions would be helpful. Thanks, Tom.

Assuming they're discrete, it might be the amp channel in the receiver. I supposed it's possible there's a failing component in the speakers crossover, but that would be my second guess. Can you temporarily hook the center up to another channel and see if the same thing occurs?
