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.

Rated 5 out of 5 by from Best bang for the buck I added to my theaterThese things added a tremendous addition to my theater experience. I have 4 of these (1 mounted under each seat) powered by an SA-240 amp and maybe 9-10 oclock on the amp and these things add an imense amount of affect to the movies. I keep the xover a little low around 50-60hz to minimize on the effect to not annoy.

Rated 5 out of 5 by from feel the musicI just installed it in my little car. Because I can't fit a big sub woofer.

Rated 5 out of 5 by from Great powerI purchased two these transducers to install into my couch. It is a pull out couch with a bed it in. I had to fabricate a wooden bracket to hold them. Because it was a pull out couch, my options for positioning them were limited. They basically sit near mid-chest level on the very back of the couch. I also purchased the Dayton Audio SA70 70W Subwoofer Plate Amplifier from Parts Express to run these. The response is great. The transducers are very powerful. I have them wired in series back to the amp. I think the amp may be slightly underpowered for this application - even at full power the transducers seem to have more left in them. Nevertheless, they make for a great addition to any action movie.

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.

Purchased 3 AST-2B-4's and the Dayton Audio SPA250. Do I wire these 3 in series (red amp lead to red wire of speaker #1, white of #1 goes to red of #2, white of #2 goes to red of #3, white of #3 goes to white of amp lead), correct, to result in 4 ohms?

Asked by: Elsid
Unfortunately there is no way to wire 3 of these to a 4 ohm load. There are only two ways to wire them properly, all in series for a 12 ohm load of all in series for a 1.6 ohm load.

Will the daytonSA 100 run 3 Aura Bass Shakers good? If not what is the return policy? Also does carpeted flooring make a difference in effect?

Asked by: Kev O
Three shakers will have to be wired in series for a safe impedance load on the amplifier. This will significantly limit the amplifiers output capability. You would be farther ahead getting a fourth bass shaker in order to wire them back for a 4 ohm load. Carpet will make no difference in performance.
