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.

• Usable frequency response: 20 to 80 Hz
• Fs: 40 Hz

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 froma 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.

AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducer
AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducer is rated 4.574 out of 5 by 169.
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.

Rated 5 out of 5 by from Great bang for the buckUsing two of these in a recliner sofa. I glued and screwed a piece of 3/4" plywood across the seat frame of each seat and mounted one shaker to each. I'm powering both in series (8-ohm load) with a 125-watt amp. Does the job and it gives the impression that the whole house is rumbling when stuff is blowing up in an action flick.Parts Express customer service is great, and I'm a happy customer.

Rated 4 out of 5 by from So far, So goodI just finishing installing my shakers (4) yesterday. They add a nice feel to my movie experience. I like a hint of feel, not to over do it. My wife even liked them.I'm running my shakers through a "Buttkicker" amp (BKA300).I hope to still get some buttkicker shakers someday. Until them, these will have to do and so far they are working nicely.

Rated 4 out of 5 by from mini imaxpaired with the SA70, I bought two of these for my 4 person long sofa. Under the advice of their phone reps, I had twisty tied mounted them to the spring frame of my sofa. As a result, an easier to move rumbling experience. I was skeptical of these vs the more premium Butt kickers versions. But it works quite well.Sturdy construction and clips with a good heft to them was enough to deliver through the 6 inch foam seating. For my condo living, this is an ideal set up for experiencing bass without waking neighbors/ the wife/ kids at night. A worthy upgrade to your home theater experience.

Rated 5 out of 5 by from Works great!Exactly what I was looking for. Added great immersion to my home flight simulator.Extra note: the amount of vibration you feel while holding the bass shaker does not represent its potential once installed. It feels weak in your hand but is VERY strong once attached to your chair or sofa.

Rated 5 out of 5 by from Super Deal!Very efficient bass transducers, easy to install great alternative of much more expensive solutionI am very happy with the results

I have an Harman kardon avr 3700 with 7.2... Can I connect 3 aura directly to the second subwoofer output? 

Asked by: Dlobrown
No, these will require a separate amplifier for power. Wiring three limits your wiring options, you would be farther ahead using two or four to get the most from our smaller subwoofer amps. With two wired in series you could use something like our Dayton SA100, with four wired series/parallel you could use our SPA250.

I want to buy 2 AuraSound AST-2B-4 and install them under my sofa in my home theater ,what amp do you recommend at lowest price from your stoke? (I need the amp to be 220V)

Asked by: avi70
The best option to power two of those would be our Dayton SPA250 which has a switchable input voltage.http://www.parts-express.com/dayton-audio-spa250-250-watt-subwoofer-plate-amplifier--300-803

I want to place under the seat in my Ford 2002 Tarsus - what do I need to drive (amp) the bass shaker? Will a class T Digital Amp LP 2020A+ work? I plan to feed RCA output out of my head to amp to shaker amp. Will this work? Low Pass needed. 

Asked by: Myounger
I would not recommend a small T amp like the Lepai for this application. For the best results you will want to use a small car amplifier that will produce around 50 watts RMS for the bass shaker. Something like below will work well.http://www.parts-express.com/boss-r1002-riot-200-watt-2-channel-car-audio-amplifier--265-3980

Hello, Would this amp be good enough to drive 2 of these? Technics REQ0251-1 100W Subwoofer Plate Amplifier

Asked by: Matt0000
That amp will power two with about 25 watts or so to each shaker. We recommend the SPA250 for a pair wired in series to get the most from them.
