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. 

The ButtKicker LFE (low frequency effects) functions similar to a loudspeaker, but instead of moving a cone and transferring sound waves through the air, it uses a patented magnetic suspension system to attach to seats and floors, thus sending the low frequency sound directly into the listener's body. Listeners can decrease the sound pressure level from the subwoofer to where the kids upstairs can't hear it, yet still feel all the bass they want. And as compared to other shakers or tactile transducers that use voice coil technology, the ButtKicker is more powerful and more musical (linear), with a true low frequency response of 9 Hz and a range of 5 to 200 Hz.

To make it easy to connect your ButtKicker, the company included several other items to this LFE bundle, including a 2,100-watt amplifier that connects to your receiver's subwoofer out, a cable package, and a chair/couch mounting accessory kit. Simply place the mounting plate under one leg of a piece of furniture and attach the ButtKicker to the other side. The kit also includes rubber isolators that sit under the furniture's other legs. Listeners can even install the ButtKicker under the floor to enjoy a full-room tactile experience.

To top it off, the ButtKicker LFE is virtually indestructible and maintenance-free. It's so reliable, in fact, that dozens of theme park owners, specialty theaters, virtual reality operators, and arcade owners are using a commercial version of the ButtKicker to boost their bottom line. So if you're looking to delight and electrify your guests with an affordable and easy-to-use full-body experience, it's time to incorporate the ButtKicker into your home theater system.
