Sometimes hearing the music just isn't enough. For those requiring a more visceral experience in their home audio system, there's the ButtKicker. The wireless, silent subwoofer transforms the bass in your audio into vibrations that, when placed strategically in a couch or chair, re-creates the "feel" of the sound. The ButtKicker kit comes with a low-frequency audio transducer, a 300-watt digital amplifier, wireless audio transmitters, a remote control and a mounting plate. It works with any audio or gaming system. The full wireless home theater system costs $400, with a la carte options also available. More Info
