## Description

Product description The ButtKicker Advance is a patented 4 ohm low frequency audio transducer that features a 1 lb (0.45 kg) magnetically suspended piston. The ButtKicker Advance 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 Advance provides powerful tactile response without the sound pressure of a subwoofer. The ButtKicker Advance is a perfect solution for couches and sectional sofas. Paired with the BKA300-4 amplifier (included in the Wireless ButtKicker Kit) you can add powerful bass response to your sound system. The ButtKicker Advance requires a minimum of 75 watts and we recommend a maximum of 400 watts. The Advance connects to the BKA300-4 power amplifier via spring loaded binding posts; we recommend 14 gauge speaker wire for normal installations and 12 gauge wire for lengthy wire runs. Please note that the ButtKicker Advance does not include a power amplifier.

Review: Haptic Fantaptic - This is great as-is, but would definitely benefit from EQ fine-tuning based on case-by-case usage. Meaning, you might want a different gaming profile from your music/movie listening profile. The amp I use this with has a LPF, so I just adjust that for my preferences, and that's enough for me. More discerning ears might want to get (probably already have) a quality EQ program to dial in the performance. On a technical note, it's worth mentioning that the claimed frequency response for this goes down to 5hz, and while that's below hearing range, you will feel the difference with this device. Most amps (including the one I'm using) only go down to 20hz, which is probably enough for most people, but again, discerning ears might want to spend a little more on an amp that accommodates the extended frequency response. An example where this difference would be felt would be in explosions/action scenes, engine notes, and gaming impacts.
Review: 4D experience - This brought my home theater from great to EXCELLENT, the rumble in this thing is insane, I use it with a subwoofer so I get the full range of sound, it feels like I’m in a Dolby cinema or IMAX, love this, it really elevates movies and music

## Questions & Answers

**Q: I have a set of four recliners.  Would an "Advance" transducer mounted in each recliner be way too much?**
A: I have one mounted beneath a loveseat.  It shakes hard enough to go just beyond the point of being comfortable. At that extreme level you can hear knocking in the unit.  For me, at that high level it's distracting & unpleasant. By adjusting the amp's cutoff freq higher to ~ 100hz on your amp you can include tactile for gun shots & door slam; or you can set it lower < 50hz for only crashes/explosions, etc.  If you want real extreme this wont be for you.  I run mine with a left over sub woofer 120 watt plate amp and it has plenty of shake in my opinion.  I ordered the Advance and the LFE version, I sent the later back.  I would say this model would is perfect for your application.  If in doubt, buy this and a smaller model and compare the two.

**Q: will i need extra accessories with this product? or it plug and play from the box**
A: I bought the wired version (there is a wireless model). Needed extras included BKA300-4 amplifier (was not included), extra rubber isolating feet for larger pieces of furniture then a single chair, cable to get signal from sub-woofer output on your surround to the amplifier.

**Q: Hello, you amplifier used to move this ButtKicker?**
A: Actually these amps will power up to 4 buttkickers--if you only need one you can go with the Buttkicker Amp BKA300-4 which costs around $229

**Q: Will this work on xbox one? it only has analog out put not digital like hdmi used this days.**
A: Signal must be analog not digital. Low frequency end of your XBox signal must be 5 - 200 Hz. And yes you will need an amp  such as the BKA1000N.

### ⭐⭐⭐⭐ Good product I would buy it again.
*by J***R on July 7, 2015*

This is my first review for Amazon. I purchased these because I upgraded the seating in my HT. I was previously using Bass Shaker Pro's for my seating. The old unit simply would not fit in the new chairs. The new seats were specifically designed to accommodate the BK4's. I have many years experience with tactile transducers. The BK4s do a fine job of transferring the LFE signal into earth shattering vibration. They were simple to install and fairly well documented. The only issue I have is the price. They are a lot more expensive than the Bass shakers I am replacing but I don't "feel" any difference. I do have 1 unit mounted in each chair. Perhaps they can produce higher levels than the Bass shakers but it is not needed for a single chair application. There comes a point where the effect is distracting from the movie experience rather than a cool addition.
