## Overview

The ButtKicker BK-LFE is a premium tactile transducer designed to deliver powerful low-frequency effects from 5 to 200 Hz, with a resonant frequency at 9 Hz. Compact yet robust, it handles 400 to 1500 watts of power, attaching easily to seats or floors to transmit bass vibrations directly into your body. Ideal for home theaters, gaming, and specialty installations, it offers a maintenance-free, virtually indestructible solution to elevate immersive audio experiences without excessive volume.

## Description

desertcart.com The only tactile transducer designed specifically to take advantage of the 0.1 and LFE (low frequency effects) channels, the ButtKicker LFE features extended low-frequency response for powerful bass and special effects. If you are looking to delight and electrify yourself and others with an affordable and easy-to-use solution, now is the time to incorporate the ButtKicker into your sound-system's design and feel what you've been missing. The ButtKicker LFE Low Frequency Effects System utilizes a patented magnetic suspension and can be used in couches, theater seating, platforms, and any type of structure. Different from other shakers or tactile transducers that use voice coil technology, the ButtKicker is much more powerful, more musical (linear), and offers true infrasonic, or low-frequency response with a resonant frequency of 9 Hz. The ButtKicker LFE utilizes a small, linear motor, which reacts to an audio signal sent by an amplifier. The system is similar to a loudspeaker, but instead of moving a cone and transferring sound waves through the air, it attaches to seats and floors, and sends low-frequency sound directly into the listener's body to accurately reproduce the "feeling" range of many natural and man-made sounds, such as earthquakes, thunderstorms, sound effects, and all styles of music. One ButtKicker LFE will easily replace two, four, or more voice coil-type shakers, and it is virtually indestructible and maintenance free. The ButtKicker LFE is used in everything from theme-park attractions and specialty theaters, to car-stereo systems, and custom home theaters. The ButtKicker LFE Low Frequency Effects System is small and unobtrusive, but powerful. Measuring only 5.375 x 5.5 x 5.375 inches (WxHxD), the ButtKicker weighs 11 pounds, and has a frequency range of 5 to 200 Hz. This unit has a nominal impedance of 4 ohms, and a power handling that ranges from a minimum of 400 watts to a 1,500-watt maximum. Product Description The ButtKicker LFE is our largest transducer and is a great fit for large installs. One ButtKicker LFE provides amazing tactile response on even the largest of couches or platforms. The ButtKicker LFE haptic transducer requires a minimum of 400 watts and we recommend a maximum of 1500 watts. The ButtKicker LFE (low frequency effects) transducer is a “Silent Subwoofer” that allows you to feel powerful bass without excessive volume. The ButtKicker LFE is a patented 4 ohm low frequency audio transducer that features a 3.75 lbs (1.48 kg) magnetically suspended piston. The ButtKicker LFE is accurate, provides powerful frequency response, is virtually indestructible, and requires no maintenance. With a frequency response range of approximately 5Hz to 200Hz the ButtKicker LFE provides powerful tactile response without the sound pressure of a subwoofer. *Dimensions: 5.375" H x 5.375" *Frequency Response: 5 - 200 Hz *Weight: 11 lbs / 5 kgs *Nominal Impedance: 4 ohms *Power Handling: 400 watts min. / 1500 watts max *Piston Weight: 3.75 lbs / 1.48 kg *Please note that the ButtKicker LFE does not include a power amplifier.

Review: Take your movie experience to the next level... these ButtKicker LFE's are fantastic ! - I have a home theater and I have installed the Aurora bass shakers in the past... they work OK and give you some good feedback. Then I stepped it up and invested in the Buttkicker LFE.. I have 2 rows of 3 theater seats and I bought 1 LFE for each row. I mounted them to the frame under the middle non-reclining seat (see pictures) and I am driving these 2 in a series by the Dayton SA1000 amplifier. This is a great setup, I generally only need to have the gain at around halfway to drive a great experience in the 2 seats. I got creative mounting these because I knew they needed to be solid... so I found these aluminum 1" extrusion bars from "8020" and mounted them to the frames with T-nuts. Overall, I don't see how this could have been done any better and I am very happy with the outcome. Remember if you run more than 1 Buttkicker LFE on a single amp, run the wires in a "series" to get the most out of the amp.
Review: ClassAB amp, and Low-Pass filtering is required. - I have a Clark and a Buttkicker. Clark is rated for 250 watts, Buttkicker is over 1000 watts. Buttkicker was twice the price, so I bought the less expensive Clark first. The application was the long roof of a bare metal limousine: It has the perfect resonant surface area for 0.0001 Hz through 150 Hz. It would be a giant subsonic subwoofer. The Clark worked (functionally), but I made one miscalculation, and two horrible mistakes. I miscalculated the force required to be applied to the roof for proper roofline deflection. The Clark only provided about 50% of the desired effect. The first mistake was pretesting it without mounting it first to a solid surface. Applying ~125 watts caused it to overheat, and it smelled like the voice coil was burning. The second mistake (fatal) was driving it with the out-of-range intermittently peaking signal of ~325 watts. It happily took the abuse until the internal guts failed and broke loose. It sounded like ball-bearings in a coffee can. Although it has internal overcurrent protection, driving it at just under its threshold can still significantly reduce its lifespan. Next, The Buttkicker is different. It does not operate on a voice coil/permanent magnet arrangement. Instead, the BC is a linear actuator / motor. It can handle the current, and based on my application, it thoroughly enjoys the abuse. There is one major requirement that I have not found listed anywhere, and you will thank me for sharing the following fact: Do NOT use a Class D amplifier to drive your low-frequency tactile transducers. It barely works... it hardly works... do not waste your time with cheaper, energy-efficient, smaller, cooler Class D amplifiers. The answer is A, but all you will find is AB. Class AB amplifiers will reproduce frequencies below 5Hz with huge amounts of power and force. You NEED this for your transducer. The last consideration when building your transducer/amplifier system is filtering. You must completely filter out anything above 250 Hz. You will need to let your subwoofers punch out anything higher than that. Going higher than 200Hz will strain the transducer, and there is no internal filtering that will prevent it from trying to buzz itself to pieces. My car stereo has menu options to electronically adjust a low-pass crossover, and has a dedicated subwoofer output (Kenwood $250 dual-DIN). The amplifier I am using is a bridged R.F. Renegade 550 (probably 450 watt peak). It has band pass and subsonic amplification control knobs. I am considering upgrading to a higher wattage amp because after about 25 minutes of SHAKING the car at 7Hz, it overheats, and shuts down. It does auto-reset, no permanent damage is done. The amount of action I get from my 550 watt amp is too much for the car to handle. I have had to bolt things back together throughout the car. Windows shake out of their tracks, a side mirror fell off, people are hurting their necks from turning to look. It really is too much, but think about it this way: the trunk is empty, and my wallet is phat. The money invested is $600 between the head unit, the transducer, and the amp, but the system sounds like I invested a few thousand! To summarize: FILTER CLASS AB BUTTKICKER 1000watt 8 AWG (30A fused at the battery) A SOCKET SET CONTACT ADHESIVE ICE DARK SUNGLASSES (and preferribly an old 6-door Cadillac service limousine) ___________________ Please share this information everywhere you can, you all have my permission.

## Questions & Answers

**Q: will one of these be suitable for a u shaped sectional couch? Each sectional (5 pieces) is attached by only a metal linkage.**
A: In your case, in all probability, only the section that the Buttkicker is mounted to will experience any significant shaking since you need a really SOLID mechanical connection between the Buttkicker and the sofa, and between the sections to transmit the vibrations.  It would be a good idea to check out some of the YouTube videos on mounting Buttkickers to sofas/chairs.  BTW, I recommend mounting the Buttkicker to the frame of the sofa, rather than using the Under-leg Mounting Kit.   The reason is that when the device is mounted to the frame of the sofa, you get forces transmitted to the structure on both the upward and downward strokes of the Buttkicker internal piston, whereas when you use the under-leg mounting method, the Buttkicker is driving its force into the floor with little motion for half of each cycle.

**Q: How many of these bad boys do I need to power a row of 4 home theater seats? 4? Or can I get away with 2?**
A: As long as the seats are attached solid you would be fine with 2 BK-LFE.  You would also require an amplifier to power them.

**Q: What is the best amp for this. Try to be spacific.**
A: I called and talked with ButtKicker, they said the Dayton SA-1000 was the best and was equal to thwir amps. There is a company called Partsexpress.com with the best price, 398.00

**Q: Where would you mount this in a car? Also how would you mount this to a car?**
A: Typically in the trunk.  It's too tall for anywhere else.  But it's not your best choice for a car anyhow; this thing requires a LOT of power.  It's moving a big piston.  And it's heavy, while you want your car light for performance.
An Aurasound or Clark Synthesis transducer is smaller, easier to mount to your seat's underside and more power-efficient.  They won't -thump- as much, but they're better choices.

### ⭐⭐⭐⭐ Almost perfect!
*by H***C on October 6, 2018*

With this Buttkicker LFE (https://www.amazon.com/gp/product/B0007P98K6/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1) and the Dayton Audio SA1000 Subwoofer Amplifier (https://www.amazon.com/gp/product/B002IAA2A8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1), it will literally shakes the entire condo (and my neighbor's too!)... way overkill for a small condo, but WOW!, makes any action movie a true "experience"... Needs some really heavy furniture to keep it planted to the floor (with the standard mounting base/bracket) when you really cranked it (or at certain frequencies).. it can start to hop/flap all over the place, losing a ton of quality/performance (proper mounting/installation is key to performance)... Certainly beats the pants off of my Buttkicker Gamer2 with 90-watt amp (the smaller Gamer2 is still great for a solid/heavy chair mount, but a little light for a home theater with large heavy furniture when you want to REALLY feel the power). I did have to buy a small table-top fan to keep it cool though, since it does get REALLY hot to the touch when I drive it REALLY hard for a long time (super low-frequency at a "constant" high volumes--good ventilation is essential)... that's why only four stars.
