Review: Huge home theater upgrade for a very small cost. - I purchased a pair of these tactile transducers to mount in my home theater seats. The impact is incredible! Don't get me wrong, I have a 15" servo subwoofer that will easily rattle the windows if I want it to; however, it still doesn't provide the experience that these little beauties provide. The experience is most akin to a high end movie theater where you feel the bass throughout your body. The lowest frequencies can't be heard anyway, but feeling them immediately improves the movie experience dramatically. To hook them up, I split my subwoofer out cable and ran one to my subwoofer, and the other split to a cheap stereo amplifier to the CD input. The result is that the signal coming into my 2nd amplifier includes only the low frequencies as established by my crossover in my 1st amp, which is set to 80hz. I hooked the bass shakers to the 2nd amp speaker outputs and can now adjust the "volume" of the bass shakers by using the volume control on the 2nd amp. Even with my volume turned down quite a ways, the bass shakers provide the illusion of an enveloping sound field and live action. I couldn't be happier with these products. I actually had to turn them way down since they shake so much. You don't need a much more expensive solution since these will output more shake than you'll ever need. I turned them way down because initially they shook too much and created a very artificial experience. With them turned down, they are much more subtle, yet they still shake my theater seats quite a bit.
Review: Very powerful bass transducer. Works great mounted to my office chair. - Wow, this thing really does turn up the bass. I bought a 6 inch wood platform and used a few RAM mount connections to mount this to my Steelcase Leap office chair. It is a removable configuration and doesn't affect the resale value of the chair. I initially had a Vybe Haptic Pad that i got for $40 which was great, but nowhere near as comfy as sitting in my chair unhindered. It is small enough, yet powerful and mounts discretely. It worked great with a below $30 Lepai 70w sub amp. It is very accurate and feels great with Music. I haven't tried Movies and Games yet, but music was always the tough sell with my haptic pad. The overall cost for the Transducer, Amp and mounting materials was below $140 which is in the ballpark of the Buttkicker Gamer 2 which is out stock everywhere at the time of this writing. My only negative is that i couldn't use a audio transmitter to make it wireless, but it's not a strike against this item. Parts that i used to mount purchased from desertcart. 1. Walnut Hollow Baltic Birch Circle Plaque-6"x6" 2. Ram Mount 2 x 1.7 Inches Base with 1-Inch Ball 3. Ram Mount Double Socket Arm for 1-Inch Ball 4. RAM Zinc Coated U-Bolt Mounting Base with 1 inch Ball This solution makes the Transducer easily removable with the twist of a knob and holds sturdy. I have it posted to the pole under the seat of my office chair. Update: I got the wireless receiver working so now this is more portable and i only have to plug in the power to any socket. Dayton Audio WS-12 Wireless Audio Transmitter/Receiver Final update: Still going years later. My setup is completely wireless now using Talentcell 12V 6000mah battery.

## Questions & Answers

**Q: Can I just hook one of these into the Preamp output on my amp and attach to my chair.  I will be using it in my audio system, not home theater.**
A: Gary these transducers are rated at 50 watts. A preamp output is not what you should consider for driving this load.  Think Amplifier not Preamp!  An amp that is capable of more than 30 to 35 watts should be best suited for this purpose.  If you download the manual for this product you can find warnings not to surpass the 50 watt per unit rating.  All* of those prior answers were Internet noise.  #1. Neither helpful nor informative #2. Borderline helpful but not informative #3. What? & Wrong! #4.* I might be too hard on Sara.  She is right to drive a group of these with hundreds of watts of power and Sara is also correct in guessing that the low preamp power will not work with the Bass Shaker.  My contention with her response is that the harm of testing is that it is a complete waste of time.  It is sort of trying to see if your toaster will work without power.  How could it?

**Q: Is the enclosure made out of metal or plastic?**
A: It is definately metal.  Weighs close to 5 lbs. (2.3 Kg)

**Q: The product description says the shaker is 5.4" wide - is this accurate? What is the spacing for the mounting holes?**
A: The outside diameter to the fins is 156mm or 6.14".  The bolt hole circle diameter is 143.5mm or 5.65".  It will take a #8 screw.  The actual vibrating area on the bottom is 130mm or 5.1".

**Q: What's the best amp to use with these? Cheap but decent quality preferred...**
A: Parts express has several amps that are good, they are made by Dayton audio.  They have a new one that looks nice, APA150.

### ⭐⭐⭐⭐⭐ Solid and good value for money
*by K***H on January 17, 2020*

Perhaps useful to compare side to side with a Buttkicker Concert Mini which as far as I can tell is the same as the driver in the Buttkicker Gamer 2. I've run these off the same amp with the same settings out of Simhub to compare them side by side. Pros: - these don't overheat. You can push them to the point that it feels like their giving their best without maxing out at certain frequencies and yes, they get a bit warm, but they don't go into melt down. - the mounting surface is flat, and as long as you have the space very easy to mount - cheap! - adequate response for corner use, in my rig anyway. - doesn't have major piston slap issues in a specific frequency range as far as I can tell. It's either fine, or volume is too high, unlike the BK which can be frustrating because you have to set the amp to avoid the low hz piston slap, and in so doing lower volume where it's much more capable (or eq out 20-30hz a little). Cons: - does not have the same deep resonance that the BK is capable of. That BK thrum that you can get from low revs is just excellent, but I've it's getting that by working hard in the 20hz -30hz range, and that's what makes the BK overheat.. so I can't really give the BK a complete win here. All in all I think it's a product that "just works". It's not the best response available, but it's easy to dial in and enjoy for hours.
