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.

Review : great, but...
This is a pretty darn effective device and is a great addition to most home theaters. My review is in two parts, the good and the bad.

The bad:

I had to get two kits for one to actually work. The transducer was bad in the first kit. The amplifier was a bit smudged (the same in the second kit, too) and the acorn nuts were of horrible quality (again, in the second kit as well). Also, I recommend that they provide more than five rubber foot pads. Many people have couches with 8 or more legs.

The good:

Easy as heck to install, particularly the platform mounting. Mounting the transducer to the couch, although easy, requires remving the usual cloth covering on the bottom of the couch. This may not make the wife happy.

Once installed the Buttkicker works well. My wife got a kick out of it when we tested it with Top Gun; we rocked and rolled. I am not sure, though, at what point the amplifier will clip. This worries me a bit. I guess I'll...


I think, explains the few complaints apropos ButtKicker BK-LFEKit Low Frequency Effect Kit with Amplifier for Home Theater not fitting or leaking.
