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

Great addition to give tactile feel in my home theater. I currently just have one installed on the foot portion of my recliner since noone else really digs on the tactile sensation of bass like I do. I ended up getting a cheap 50W stereo amp with RCA in/out to drive it and it gives plenty of rumble. I have it connected to my minidsp 2x4HD to adjust the crossover so that it only kicks in on 40Hz and lower. I can only imagine it would be even better if I was able to mount it directly under the seat or somewhere closer to the lower back section of my recliner, but the options were pretty slim for mounting with my particular recliner.

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.

I have this hooked up to a very reasonably priced amp (ZK-502H 50W+50W Bluetooth... https://www.amazon.com/dp/B08L38Z841?ref=ppx_pop_mob_ap_share).And from the amp to the computer via USB, so that the computer will recognize it as a completely different audio device than the sound card, since that is already used to drive speakers.This way, in iRacing (and probably other titles,, dunno) I can set the LFE output to its own device which drives this shaker only with LFE outputs, and not the whole game sound output.I've literally drilled holes in the bottom of my racing rig's seat, to mount this on the bottom.This setup is petty amazing. Nearly inaudible. But remarkably strong and precise. At default LFE settings, this thing will just about throw you out of the seat. Yes, that's a slight exaggeration. But it's enough to blow your mind.I never thought that I would like a shaker in my rig. Seemed too gimmicky to me. But when a buddy loaned me his super cheap Dayton shakers and an even cheaper amp, it impressed me enough that I knew I had to have it. The immersion was much better than I expected. But it had to be better of course. Looking at some of the known brand shakers for this purpose, I got seriously sticker shocked. I knew I could dyi something comparable for a fraction of the cost.This setup fits the bill! Not terribly expensive. And, I can't imagine how a 4 shaker setup would ever be needed after experiencing this. .I am planning on buying a 2nd one tho, to put on my pedel plate using the 2nd channel of the amp. But I may have to upgrade my amp to one that has balance control. I'm pretty sure that the pedel plate one will not need near the same power. But there's no way to control that with my current amp.But still, even with an amp upgrade, I'm still going to come out at WAY less cost than buying brand names.

Wow, this thing really does turn up the bass. I bought a 6 inch wood platform and used a few RAM mount connections to mount this to my Steelcase Leap office chair. It is a removable configuration and doesn't affect the resale value of the chair. I initially had a Vybe Haptic Pad that i got for $40 which was great, but nowhere near as comfy as sitting in my chair unhindered. It is small enough, yet powerful and mounts discretely. It worked great with a below $30 Lepai 70w sub amp. It is very accurate and feels great with Music.I haven't tried Movies and Games yet, but music was always the tough sell with my haptic pad. The overall cost for the Transducer, Amp and mounting materials was below $140 which is in the ballpark of the Buttkicker Gamer 2 which is out stock everywhere at the time of this writing. My only negative is that i couldn't use a audio transmitter to make it wireless, but it's not a strike against this item.Parts that i used to mount purchased from Amazon.1. Walnut Hollow Baltic Birch Circle Plaque-6"x6"2. Ram Mount 2 x 1.7 Inches Base with 1-Inch Ball3. Ram Mount Double Socket Arm for 1-Inch Ball4. RAM Zinc Coated U-Bolt Mounting Base with 1 inch BallThis solution makes the Transducer easily removable with the twist of a knob and holds sturdy. I have it posted to the pole under the seat of my office chair.Update: I got the wireless receiver working so now this is more portable and i only have to plug in the power to any socket.Dayton Audio WS-12 Wireless Audio Transmitter/ReceiverFinal update: Still going years later. My setup is completely wireless now using Talentcell 12V 6000mah battery.
