Product information The ButtKicker Advance is a patented 4 ohm low frequency audio transducer that features a 1 lb (0.45 kg) magnetically suspended piston. The ButtKicker Advance is accurate, provides powerful frequency response, is virtually indestructible, and requires no maintenance. With a frequency response range of approximately 5Hz to 200Hz the ButtKicker Advance provides powerful tactile response without the sound pressure of a subwoofer. The ButtKicker Advance is a perfect solution for couches and sectional sofas. Paired with the BKA300-4 amplifier (included in the Wireless ButtKicker Kit) you can add powerful bass response to your sound system. The ButtKicker Advance requires a minimum of 75 watts and we recommend a maximum of 400 watts. The Advance LFE connects to the BKA300-4 power amplifier via spring loaded binding posts; we recommend 14 gauge speaker wire for normal installations and 12 gauge wire for lengthy wire runs
