Hey everyone. My PB12 Plus /2 sub which I've had for about a month now has a problem. I just noticed today when I went to turn the volume down in the back of the sub that a low but audible scratchy sound comes from the woofers. At first I thought I was hearing things so I continued to just turn the volume knob up and down fully and sure enough, a scratchy sound every time the knob was being adjusted. This doesn't happen unless the volume knob is being adjusted, left alone and the sub performs as expected
. It's not that loud, but with nothing playing, I can easily hear it; should I be worried about this? I'm not one to be adjusting the volume much on the sub but I don't want to run into any problems down the road.
Thanks in advance.
Jim
