sub playing by itself


I am getting fm radio thru my HT sub. What is the best way to stop that?

I used to have a similar problem, which I was able to fix by changing interconnects. I won't claim to understand radio frequency interference or shielding or much about electricity, even, but I'd look to the interconnects first. If you can't swap in others because of length, etc., perhaps changing where they run might help.

1. Change your cable orientation; just a little bit can do it. One of my active speakers was picking up 94.9FM (with a nearby 50 KW transmitter and wavelength 4X the vertical speaker wire length) until I made minor adjustments to where the excess was in the cabinet.

2. Change interconnects to ones with better shielding. They can act like FM antennas and better shielding can reduce this.
