Feel What You’ve Been Missing

The ButtKicker brand has been shaking up the entertainment experience since 1999 with their state-of-the-art bass technology. Using low-frequency transducers to emphasize the rumble instead of the racket of the traditional subwoofer, they offer powerful chair-rattling impact at a small size and reasonable price. Available by the piece or by the kit, ButtKicker products can be mixed to match any consumer. Don’t worry about maintenance, either. These transducers are made from quality material and are designed to last. They have been used and loved by the most demanding professionals in music, gaming, and home theater installation. All ButtKicker products also feature a one year warranty.

The Strong, Silent Type

The BK-LFE silent subwoofer is a hallmark of ButtKicker’s line. Capable of handling the lowest of frequencies, you can expect to feel the deepest bass without worrying about disturbing your neighbors. As their largest transducer available on the market, the LFE is perfect for home theater installs. They can be seamlessly integrated and hidden beneath chairs, couches, or risers and platforms. FireFold also offers the BK-CMAK, a chair-mounting solution for the BK-LFE, which includes the hardware and tools you’ll need to attach this transducer to your furniture.

Installation of the LFE is simple enough to do on your own. All you need to do is connect it to the BKA-1000-N power amplifier to the subwoofer output of your receiver. Then, using speaker wire and banana plugs, connect the amplifier to the LFE.  For most projects, 14G speaker wire will be perfect but for longer runs you may want to upgrade to 12G. The ideal location to stash your new transducers depends on your current room’s architecture and furniture. Luckily, all of ButtKicker’s cutting-edge products include a detailed user manual and an installation guide to help guide you through creating your quality 4-D theater presentation.
