Add a whole new dimension to your home entertainment setup with the ButtKicker BK4-4 4 Ohm Low Frequency Audio Transducer Silent Subwoofer. Think of the ButtKicker advance transducer as a "silent subwoofer" that you feel instead of hear. It utilizes a 1 lb magnetically suspended piston that responds to the low frequencies of movie soundtracks and game audio. Great for people who are looking for that large movie feel sound without disturbing your sleeping child, or neighbors. 

Simply attach this transducer onto, or underneath your home theater chairs, risers or platforms. Then, wire it to the audio output of your components. It can connect to either the subwoofer output of a home theater system or to the left- or right-channel preamp output of a 2-channel stereo system. When activated, the ButtKicker Advance physically vibrates in sync with the low audio frequencies, providing you with a more immersive experience.

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 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. Please note that the ButtKicker Advance does not include a power amplifier.
