Buzzing sound coming from speakers
I have the Polk rm75 5.1 speaker set combined with a yamaha rx-v571 receiver and a Polk pw10 sub. After about 5 days the center and left channel speakers started putting out a loud buzzing sound. This only happens when BOTH wires are plugged in and it doesn't matter which side (+ or -) the wires are in. I have tried new wire and tried changing the connection at the receiver itsel but I still get the buzzing sound. It happens immediately after the receiver is turned on. Not reallysure what to do and Polk support is only open mon-fri.

Swap the right channel speaker with the left channel speaker. If the buzzing still comes from the left channel, your AVR has a problem. If the buzzing moves to the right channel, your speaker has a problem.Political Correctness'.........defined

Thanks for the reply. I tried a different speaker and am still getting the buzzing sound. It sounds like it is picking up a radio station but isn't quite at the correct frequency b/c I can hear songs playing but it is too quiet (even when the volume is way up) to make out. Am I still looking at an issue with the receiver? -
I believe so. Any chance you can borrow an AVR from a friend?Political Correctness'.........defined

Could be a variety of things really. Are you using shielded cables ? I would first disconnect the subwoofer cable from the receiver and see if that helps at all. Also, are the wires on a carpeted floor ? If you have wool carpet, those are terrible for static. Another thing you can try is just move the avr and 2 speakers to another room and see if you get the same buzzing. If not, then at least you know it's not the avr and may have to do with cables, static, ground loop, or the outlets.
I'm alittle confused when you say it only happens when both wires are plugged in. They should be...always. Positive to positive, negative to negative.HT SYSTEM-

Maybe there is a Bee in the speaker?
I would agree with tony sounds like your cables are not shielded or shielded enough.
