Dayton Audio BST-1 High Power Pro Tactile Bass Shaker 50 Watts RMS, 4 Ohms Impedance - Turn Any Surface into a Speaker System - Generates Subwoofer Lows

My first foray into these transducers was when I sold my VR headset in anticipation of the new model coming out. Missing the immersion and playing flat screen games, I was thinking, what can I do? I remembered years ago a friend showing me this thing called a Buttkicker he had in his home theater setup so I looked into that. Too expensive. I stumbled across these guys. I initially bought one. I removed the bottom of my office chair, cut a piece of plywood, got some longer bolts and bolted it all back together. Now I had a solid place to mount this. I got a cheap Nobsound 100w amp with an adjustable low pass filter. I plugged it into an extra usb sound card on my computer, ran my audio through Voicemeter Banana, and was blown away. I don’t think I could ever play games without it again. At half volume this thing shakes the chair like crazy. It adds so much immersion! Love it! Fast forward, the new Vr headset came out, I missed the shaker when playing standing VR. I began figuring out how I would make my own bass transducer vest. I initially was going to go with the small Dayton pucks. I bought a four pack and one was dead on arrival. I still wired them up and they have an impressive shake but I didn’t like the flimsy wires and just really like these bigger Dayton transducers I can plug my own wires into. I bought a second one. I ran them parallel, pulling a 2 ohm load from my amp, which it can handle and puts out its full 100 watts at 2 ohms. I initially just threw them into a cheap chest bag as a proof of concept with a long speaker wire running to my amp. It worked like I hoped but I wanted to not be tied to a cord for room scale wireless VR. I got a cheap swat tactical vest, the kind with the insertable armor. I cut a 1x12 piece of wood to fit in front and back. Then I screwed these transducers to it front and back. I got a power wheels 18v Ridgid battery adapter and a plug that fits my Nobsound amp. The batteries put out 19-20v which is perfect for my amp. I wired it all together and now I have a mobile transducer bass vest, powered by my drill batteries. I plug it into a headphone splitter on my VR headset. Wow!! This thing is heavy. 15lbs plus. But it is incredible to wear while playing games. One of these is enough to shake a couch, two of these is overkill but oh boy, will it kick you hard. These transducer are heavy, well built, and just amazing to play around with. Have fun with them!

Have a 9.4 system. Installed these on the frame of my couch. Four screws drilled directly into the wood frame on back side of my couch. Buying doing so, the rumble goes through the whole frame of my couch. Didn't want to put it directly under the seat cushion and glad I didn't I have them tuned to about 60hz and give that perfect amount of feel when the base hits. Example: Watching "Top Gun Maverick" you get to feel the rumble of the jet engines which elevates the movie watching experience. Not good for sleeping, they will wake up if you pass out depending on what you watching. The key is to tune them based on your surround sound system. I run a Denon and it does have the option for "tactical transducers" so it's easy to manage the experience you want from them. If I'm watching just an average television show, I don't want to know they are there. Awesome addition if you want to actually feel the base kick while watching a move. Adds a different experience when playing video games as well.

This worked great in my couch. You can feel the bass.

I have no experience with any other bass shakers so can't compare to others, but since installing one of these in my home theater, I have been amazed at how much more immersive of an experience I have watching movies or just listening to music. I thought my sub woofer was cool, but little did I know that there was so much more sound (and feeling) that I wasn't getting with it. This shaker will bring new life to old movies and music.I installed this shaker in a matter of minutes in the back of a La-Z-Boy style recliner by putting it between metal springs and the insulating material (there wasn't a good place to mount it directly to wood). This worked great and didn't require any tools, although I will probably use some zip ties to hold it in place just in case.Now I want to install a second one under the seat :-)I used these amplifiers with this shaker, both worked great:https://www.amazon.com/dp/B07MR6YCQ1/https://www.amazon.com/dp/B07PN9LZ4R/Important: These things NEED airflow, otherwise will get extremely hot! I would imagine hot enough to start a fire if you're listening to a lot of music that has a lot of bass. I was testing one under a pillow on my couch, got up for a minute and forgot it was on with music playing for a good 20 minutes at least. When I got to it, the shaker was too hot to handle and eventually stopped working :-( My fault... I wasn't thinking. Just don't cover the entire thing like I did. Depending on your installation, it might be advisable to install a thermal fuse and/or an exhaust fan.
