I have a problem with interference in my subwoofer caused by my cable TV. I've read about this before (I believe somehow grounding is the source of the problem?) and the solution I found was to get two simple parts from Radio Shack http://www.radioshack.com/product.as...5Fid=15%2D1297 and http://www.radioshack.com/product.as...5Fid=15%2D1230 . If you put these back to back the noise was eliminated. HOWEVER, this caused all cable channels above channel 50 or so to be incredibly bad as far as static in the picture and sound. If we plug the cable straight into the wall without the transformer thingies the channels are fine, but the subwoofer buzzes. Is there another solution? Thanks.
