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.
