AurasoundAST-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.

Works great

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.

I bolted just one of these to the bottom of my sofa, powered by an inexpensive Fosi audio amp (<$100) with a low pass filter. All in I’ve spent around $150-200 on the setup, and this easily made the biggest impact of any other single piece in my theater setup, rivaled only by the addition of a subwoofer vs relying on bookshelf speakers alone for my system. But to compare, the sub easily cost 10x as much as one of these (svs sb2000 pro), and they compliment each other perfectly- I can even mute the sub late at night and still get some tactile bass from this device when watching after the family is in bed. For reference, my setup is a 4.1.4 channel atmos system in my living/great room. If you’re a theater fanatic with a huge budget looking to outfit a dedicated theater room with multiple subs, acoustic perfection, 200” screen, and expect to be thrown like a rag doll by your transducer etc. you’ll want more/possibly different transducers and higher power, but for my purposes (making action movies more immersive and entertaining for the family if you already have a basic surround system) this thing is excellent. Importantly, it doesn’t seem to bottom out or make significant noise, and power requirements are low enough for this device you don’t need to drop a boat load of money on a suitable power amp for it like you do with many of the competing devices. Binge watched “The Pacific” this week and felt every mortar shell. 6 months in and I still smile every time I throw on an action movie.
