ButtKicker ® LFE Kit Subwoofer Speaker

Ideal for movies, music, and gaming, the ButtKicker LFE " silent subwoofer " lets users experience realistic special effects and concert-quality music without waking the kids or disturbing the neighbors. Rather than emitting loud rumbling sounds during each explosion or heavy bass passage, the ButtKicker simulates the " feeling " of the effect through your couch, chairs, and other furnishings, letting you sense the low without the excessive volume. The device accurately mimics the sensation of many natural and manmade sounds, such as earthquakes, thunderstorms, rocket launches, waves, explosions, tornadoes, volcanoes, dinosaurs, sound effects, and all styles of music.

Best of Breed

The Buttkicker is a "tactile transducer", meaning it turns sound into shaking. It's just one of four players in that niche; the others are Clark Synthesis, Aura Bass Shaker and Crowson. But the Buttkicker is the best; the Clarks are less intense and less concentrated in the low frequencies, the Auras are $20 units with all that entails (such as lack of shake and lack of finess) and the Crowsons are purely under-couch devices.
