Features

  • Offers true infrasonic, or low-frequency response with a resonant frequency of 9 Hz
  • Attaches to seats and floors, and sends low-frequency sound directly into the listener's body
  • Accurately reproduce the feeling range of many natural and man-made sounds
  • Power handling ranges from a minimum of 400 watts to a 1,500-watt maximum
  • Measures 5.375 x 5.5 x 5.375 inches (WxHxD), and weighs 11 pounds

Description

Low Frequency Effects ButtKicker version for Home Theater use - 4 ohm 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.

abunda_amazon_reviews 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!

I'm really addicted to the effect now, watching an action or sci-fi flick without a Buttkicker would be like watching the movie on a 27" screen. There are three sizes of Buttkickers, the BK-LFE is the largest size. If you have a powerful subwoofer, you really need the largest Buttkicker to go with it. However, I found that the LFE tracks in newer movies (Star Wars VII, VIII, Mad Max Fury Road, etc) have a wider dynamic range than older movies, and the loudest passages can cause the Buttkicker to "bottom out" and it sounds like an impact wrench when it hits the stops. This doesn't happen very often, but unfortunately, it often coincides with very intense scenes (Kylo Ren interrogating Rey in Star Wars VII, first 30 minutes of Mad Max), and it can cause you to drop out of the "suspension of disbelief" key moments in the movie. To that end, I am using two Buttkicker BK-LFE's on my sofa, and the effect is absolutely fantastic, intense shaking with no unwanted rattling.

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.

Creates a truly immersive movie experience.
The Buttkicker BK-LFE in conjunction with your subwoofer really helps to create an immersive experience when watching movies with a good LFE sound tracks. I'm really addicted to the effect now, watching an action or sci-fi flick without a Buttkicker would be like watching the movie on a 27" screen. There are three sizes of Buttkickers, the BK-LFE is the largest size. If you have a powerful subwoofer, you really need the largest Buttkicker to go with it. However, I found that the LFE tracks in newer movies (Star Wars VII, VIII, Mad Max Fury Road, etc) have a wider dynamic range than older movies, and the loudest passages can cause the Buttkicker to "bottom out" and it sounds like an impact wrench when it hits the stops. This doesn't happen very often, but unfortunately, it often coincides with very intense scenes (Kylo Ren interrogating Rey in Star Wars VII, first 30 minutes of Mad Max), and it can cause you to drop out of the "suspension of disbelief" key moments in the movie. To that end, I am using two Buttkicker BK-LFE's on my sofa, and the effect is absolutely fantastic, intense shaking with no unwanted rattling. You are really there.

By far the best bass shaker this side of the Crowson Shadow 8 ...
By far the best bass shaker this side of the Crowson Shadow 8 motion actuator. I started with the Aura pro's and they work good but are weak below about 30hz. The Buttkicker LFE is good all the way down to 5hz. and is at least 3x stronger at every frequency, prob more. Be sure to power it with an amplifier that has a flat response down as low as possible. I use a QSC RMX 1450 bridged with stellar results. The QSC is good for about 1300 watts RMS and is flat all the way down to 5hz. I mounted the unit on a piece MDF bolted to the metal frame under my dual reclining couch and it really compliments the 6-18" subwoofers in our home theater.

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.
