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.
