*Cable lengths more than 50 feet should be avoided even if the cable size is adequate, as the ability of wire to transfer high frequency sound is diminished regardless of the cable gauge. Best performance is achieved by moving the amplifier(s) closer to the speakers in order to reduce the speaker cable length.
