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

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.

Rated 5 out of 5 by from Super Deep (( SubBASS ))I am very happy with my 2 Aura Pro Bass Shaker, I now have more SubBass than a NightClub :D

Rated 5 out of 5 by from Very cool piece!I used one of these transducers in my home theater underneath my couch. I enjoyed watching movies with exciting explosions, because I knew my seat would be a rumbling!
Date published: 2014-06-21
Rated 5 out of 5 by from Must have home theater accessoryI installed 4 of these coupled with a SPA250 amp from PE and after a small break-in period, the output and impact is incredible! I recommend using with a standard sub and tuning the shaker amp crossover to ~50hz or lower to let your sub do what it's supposed to and let the shakers ignore mid-upper bass and focus it's impact on the lower registers to emphasize gunshots, explosions, etc. When my wife saw the couch flipped over and the cover pulled back she rolled her eyes but after a couple weeks with them installed, she's excited to watch movies that "rumble the couch". Mission accomplished, thanks Parts Express!

Rated 5 out of 5 by from Nice compliment to HT subwooferI added four of the aura bass shakers to my couch and love seat in my home theater room. The added sensation is a nice compliment to my existing sub. Since my room is in my basement and my floor is tile I was looking for added oomph and these tactile transducers deliver. I love the look on people's faces when they sit down for the first time and that bass hits. My sub rattles the walls but due to the tile I never felt it like I can now. I recommend these units.

Rated 5 out of 5 by from Great addition to your Home Theater experience!I purchased 2 of these shakers about 4 years ago and they've been a great and reliable addition to my Home Theater. I recently upgraded my seating to a six piece sectional and ordered 4 more of these units to my system. I love the responses I get from friends who come over to watch a movie and are shocked to feel every impact of every gun shot or explosion and can't believe the feeling! Highly recommended!

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

After reading all of the reviews I gather that a lot of people are using plate amplifiers to drive their bass shakers. I'm curious about where you mounted the plate and looking for good/creative ideas for  placement. 

Asked by: TexanDevil
Mounting locations for these are endless, it really depends on application. As long as there is sufficient ventilation around the heatsink, the placement won't really make any difference. These can be mounted in their own enclosure or even into the wall.

Sorry for the simple question, If I wanted to use this and a normal subwoofer with the SA70 amp, is there any way I could connect both to the amp without losing power to the sub? Could I simply just get a y-cable and run it from the amp to both?

Asked by: tonedeft
Unfortunately there is no way to do this properly. You will want to have a separate sub on both drivers to control impedance, output power and volume flexibility.

Can these be used outdoors attached to the underside of a wooden deck?

Asked by: RBMike
Unfortunately these are not weather resistant so I would not recommend using them under a deck. About the only option we have for this would be the all weather Clark transducer which is much more costly.http://www.parts-express.com/clark-synthesis-aw339-all-weather-tactile-transducer-bass-shaker--300-866

Envision a chair with the shaker on the back, except for use with some Grado ear phones.  The phones are driven with a DTA-120.  How to take off the signal to a subwoofer amp like a SA70 which would drive the shaker?  Worth doing for music?

Asked by: CHJ1
About the only way to do that properly would be to split the headphone output sending one side to the headphones and the other to the RCA Input on the SA70 amplifier.

Do you need a crossover or is it built in?

Asked by: sharky222
By nature these will not play very high in frequency but a crossover is still recommended for the best results.

What is the best way to install - physically? For example, in a sofa, should it be secured to something solid, like the frame or floor below? Or is it better to place inside the cushion as close to the person as possible?

Asked by: M7CC
These need to be mounted to the frame of the couch or chair in order to transfer vibration throughout all seats. Sometimes this means mounting a narrow board to the frame of the couch and attaching the shakers to this.
