Product Details

AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducer

The AuraSound AST-2B-4 Pro Bass Shaker—also known as a butt shaker, or tactile transducer—works on the principle that low bass is mostly felt and not heard. Experience earth-shaking bass from all of your media: music, computer, movies, or video games. The AuraSound Pro Bass Shaker was designed originally for automotive applications to produce big car subwoofer bass without taking up valuable space in the vehicle's trunk. The AuraSound Pro Bass Shaker is ideal for convertibles and sports cars, where installing a large car stereo subwoofer is not practical. Can also be used in the home to make your own movie or video game chair.

The AuraSound Bass Shaker simply mounts to the floorboard under the seat or to the bottom of a chair to send vibrations through the structure, allowing you to feel awesome bass. The Pro version bass shaker handles 50 watts of power and produces more driving force than a standard shaker. Connects to an amplifier like an ordinary speaker. Use an array of Bass Shakers for larger surface areas like couches or love seats by utilizing a conventional series-parallel wiring configuration. AuraSound part number AST-2B-4. Sold and boxed individually and also available packed 16 units per case.


• Power handling: 50 watts RMS/100 watts max
• Impedance: 4 ohms
• Usable frequency response: 20 to 80 Hz
• Fs: 40 Hz
• Force peak: 30 lbs. per ft.

Want to feel your music? The Bass Shaker Pro products allow you to experience every thump, thrust and shake...the way bass sound was originally intended. Aura's patented technology preserves the sound pressure levels so there's no distortion while enhancing the bass energy delivered from your stereo. We're taking surround sound to another level..... 

Bass Shakers from Aura Systems add the exciting dimension of feeling to the sights and sounds of video arcade games, movies, stage shows and multimedia attractions! By actively converting bass sound waves into spine-ringling vibrations, Bass Shakers turn entertainment into a "moving experience"! 

Bass Shakers bring coin-operated video arcade games to life by transforming a game's audio output into body-pulsing vibrations. With Bass Shakers installed into arcade seats or floor platforms, players can feel everything from a fighter's punch to the roaring engine of a formula one race car. 

In movie theaters, the action jumps off the screen, the soundtrack comes to life and the entire experience is intensified. Bass Shakers hook up like a speaker and easily mount directly to a standard theater seat. 

Installed in seats, tables, booths, floors of showrooms and stage theaters, Bass Shakers provide audiences with a more complete entertainment experience. Las Vegas stage extravaganzas, hit Broadway musicals, and rockin' concerts virtually jump off the stage into the audience. Bass Shakers are ideal for bringing music, on-stage special effects and laser shows to life. 

Bass Shakers turn up the revenue potential of any entertainment experience. And thanks to low purchase, installation and maintenance costs, the Bass Shaker is a virtual winner in the race to provide affordable upgrades and enhancements to existing facilities.

Rated 4 out of 5 by from Strong little transducer!I brought these hoping to add a little extra tactile experience to the HT. These shakers deliver strong, realistic tactile feel to the movies.

Rated 5 out of 5 by from Finishing Touch!Okay, if your like me you have your home theater set up and your looking for that little extra detail. Well look no further. I installed one of these babies on my side of the sofa and like others the Wife could care less at the time. Once I tuned it in with my system, we watched the American Music Awards. I couldn't believe the difference, it was like being there with the added bass sensation, and I have two nice subs hooked up already. I had the wife sit in my seat to demo it and she immediately said buy another for her. Do yourself a favor, and any others that want to really experience the movie or music, and buy one for each seat that will be occupied.

Rated 5 out of 5 by from feel the vibesbought 4 of these paired with a Yung SD200 200w sub plate amp for my 2 places sofa . Great addition to a subwoofer for home cinema . You actually feel the low bass the way it was meant to be . I just love it

Rated 4 out of 5 by from Great bassI approached this with low expectations and was elated with the results.  I have a very expensive sound system with a Velodyne DD+ subwoofer.   Adding bass shakers made an enormous difference in the experience.  Suddenly you could feel the bass and the drums without having to turn it up load enough to annoy others in the house.  I did not feel any disconnect between the sound stage and the Aura effect either.  Highly recommended.

Rated 5 out of 5 by from Awesome x 4I bought 4 of these a couple of months ago and they are totally amazing considering there behind the sofa on the lower plank ( not even under the seats or behind them !!!) I've used 3 for a 3 seated sofa and 1 on the 2 seated positioned in the centre . Films that reall make these rock when wired in series/parallel are 2012, Rambo , and especially horror !! My daughter watched sinister and said it was no where near as scary as when she watched it with tactiles , a good av receiver and surround speakers with a independently powered sub are a must and trust me ..... Your local cinema won't even come close !!!!!!!! Awesome 4some !!!!

Rated 5 out of 5 by from Great addition to theater room.I bought 4 of these, 2 for each two seater reclining seat. I wired them in series-parallel to keep the 4 ohm load. I connected them to the SA230 but also considered the Dayton Audio SPA250 250 Watt Subwoofer Plate Amplifier but chose the SA230 to place it in the rack rather than build a box or mount it in the wall. I connected it with the LFE input and am letting the preamp control the crossover. At times music and other low sounds can shake so you might consider adjusting the crossover lower to eliminate some of this. My results have been awesome! It really adds impact and I enjoy listening to music with them on as well I would highly recommend them. Mounting on my chairs was challenging but there are many recommendations for various scenarios using google. I haven't tried any other brand but for the price I don't think you can beat the results. You won't regret it.

AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducer

Hi there. Do I need to buy an amp to connect 4 of this shakers. If so what do you recommend? Thanks 

Asked by: Pauloalex
Yes these will require their own amplifier. Our best recommendation for four of these would be the Dayton SPA250 below. The with the shakers wired in series/parallel the amp will see a 4 ohm load.http://www.parts-express.com/dayton-audio-spa250-250-watt-subwoofer-plate-amplifier--300-803

I have a denon 7.1 receiver and an old Onkyo 7.1 receiver. Would I Split my subwoofer out with a Y splitter so that it sends a signal to my sub and then the other end goes to a subwoofer in on the Onkyo? Then what? How do I get the signals to the speakers

I wanted to know if this would work on a sports bike motorcycle if i put against a fairing

Asked by: alex8
Yes, it should be effective if you mount it to a fairing, provided that the fairing itself is not very rigidly mounted and can vibrate or move when pushed/pulled. If the fairing is very rigid, then the bass shaker will be less effective.

Hi guys, how do I connect this Bass Shaker to the sub-out of my soundbar?  Can you recommend a couple of amplifiers I can get from you?   Thanks

Asked by: chitodb
If you are only using one bass shaker, the Dayton SA70 amplifier would be a good choice to pair with this.

I am looking to install 8 of these on individual chairs in my home theater. I understand there is a way to wire them all together, but am looking for a suggestion on what Amplifier to use to power all 8 of them? Please let me know what you can suggest.

Asked by: aventura
Eight of these would need to be wired series/parallel for an 8 ohm load. I would recommend our Dayton SPA1000 or SA1000 amplifiers for this, which will deliver about 500 watts RMS into that load.http://www.parts-express.com/dayton-audio-spa1000-1000w-subwoofer-plate-amplifier--300-809http://www.parts-express.com/dayton-audio-sa1000-subwoofer-amplifier-rack-mountable--300-811
