AST-2B-4 Pro Bass Shaker Tactile Transducer

I bought a couple of those and a cheap 100w stereo amp which I connected to the subwoofer 2 output of my main amp. Attached both to one seat, not knowing what to expect, and the vibration was so strong it was uncomfortable! I then moved one of the shakers to the other side of a 6 seater sofa and it was still too much so I've had to turn the amp down to about 30% - it's now a great addition to the home cinema, and really adds a bit of extra sensation to the cinema experience. Bought then for a bit of a laugh, but yeah, quite impressed!

Gimmick.....hell no, Bassy.....hell yes!!.... It's that good the missus has been watching a pneumatic drill full blast on YouTube on repeat for the last 3 hours! Highly recommended 👍👍👍

It wobbles me nicely. The speaker connectors as you would expect from the picture are easy to use. It can do slow chugging and it can do constant vibrating. Bursts to buzz. It's under the mattress I sit on.

I'm not sure if I have received a defective unit, but one of the two bass shakers I have ordered is MUCH weaker than the other, I have tried different cables and applications to no avail. An expensive defective unit..

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.

Cumple de sobras con su cometido,dos son suficientes para mover mi sofá.

These bass shakers are absolutely phenomenal! I originally purchased four, thinking I’d need that many to really feel the impact. However, after setting up just two of them, I quickly realized that’s all I needed. These things pound! The amount of vibration and immersion they deliver is insane. For gaming and movies, the experience is next-level. Explosions, engine rumbles, or even subtle effects like footsteps feel incredibly realistic. The shakers add a tactile layer of immersion that truly makes you feel like you’re part of the action. Whether it’s an intense firefight in a game or a high-octane chase scene in a movie, these shakers bring it to life like never before. The build quality is impressive, and they’re easy to set up with the right amp. Once configured, they work seamlessly without needing constant adjustments. They also handle high volumes and heavy usage without any signs of strain or overheating. While I initially purchased four shakers, I ended up returning two because the power of just two was more than enough for my setup. They shake like crazy and completely transformed my gaming and home theater experience. If you’re on the fence about adding bass shakers to your setup, do yourself a favor and go for it. Just two of these will blow you away with how much they enhance the immersion. Highly recommended!
