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

This thing is amazing. It sure does add another dimension to movie watching. The movie Twisters is perfect with it. HeheI recommend.May need to get more for my other seats now.

Value for money is really good, adds a lot of immersion to movies and games, setup was a bit confusing at first but no rocket science.(used a Fosi Audio M0-3)

I have a pair bolted to my sim racing rig and they work great... now that I have two that work. One of the two first shipped was obviously used (paint worn off mounting holes) and leaking oil. I don't think they check returns and got stiffed on one, which was shipped to me.

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!

I bought one of these to use as a bass shaker on my gaming chair for DCS. The first one that came felt fine with low/light vibrations, but anything moderate or heavy would cause the transducer to rattle badly. I found some videos and Reddit posts showing that the means of holding the magnet in place is two plastic pieces used as springs and that these are prone to breaking. I exchanged the one I had hoping the second would be better. It arrived with damage to the box, the bottom partially open and the hardware kit missing. Thankfully this one works fine (for now) and I used the hardware kit that came with the first one.Now that I have a working bass shaker installed, it is a great addition and adds another level of immersion.

SUMMARYThe BST-1 is not a necessity for a home theater, but boy does it add something to the overall theater experience. I don't think I will ever go back to watching movies w/o them turned on. I think "Bass Shaker" although techincally is what it does, to me seems to have a negative tone to it. Properly setup think of it as a subwoofer extension. They seem to be built well, and have lots of heat sinks to get rid of the heat when driven hard.CONFIGURATION:As great as these are, they need to be installed and setup properly. The BST-1 needs to be anchored very securely to a flat wood surface for maximum performance and to eliminate rattles. Much like the configuration of all of the speakers in your home theater it is important that everything is balanced properly. If you look at these as an extension to your subwoofer like your subwoofer is an extension using bass management to your center / L/R/Surround / heights etc. The BST-1 is rated at 10-80 hz, but will make sounds at higher frequency's so it is important to have the signal crossed over (the install guide says 80hz), I have mine at 80hz w/ the sub crossover and it seems fine. So when very low frequency's occur in movie sound tracks your sub is doing what it can, but these add that extra low freq (even below human hearing). Its the really low frequencies is where these really shine to "extend" the overall low frequency impact that your home theater has. I also find that I can run the subwoofer (and the overall theater) at a lower output and with the BST-1. The experience is more enjoyable and better at the lower sound levels plus the BST-1. There are other "bass shakers" out there but they are more expensive and I would have a hard time to imagine that they would be that much better.INSTALL DETAILS (For those who want to know)I am using (3) in a sectional with a wood frame (see pics). The sectional sits on a concreate floor. These are 4 ohms each I have (2) wired in series for total 8 ohm load to one of the amp channels and (1) wired to the other amp channel. I then paned the amp output to the speakers in series to balance out the power and level. I am using a 100w per channel amp dedicated to these (an old 2 channel receiver) so I can shut them off (and adjust the volume) / balance if needed. The input to the amp is the sub output of the home theater receiver (that handles my other speakers) sub crossed over at 120 hz. spilt to the L/R channels of the dedicated amp.For video games, we up the level, for movies we turn it down so it just "hits" when it adds to the movie and does not distract normally. I found that I needed to tighten some of the parts on the sectional to avoid vibrations at the very lowest frequencies.Update 2-23-22 - Still going strong after about 2 years of use at least 1 / week. Updated crossover for the Sub and BST-1 from 120hz down to 80 hz. My Front/Surround/Ceiling all crossed over at 80 hz now. I think they (The BST-1) work better crossed over at 80 vs 120hz. Still a great investment in my opinion.GOOD DEMO's for the BST-1Jumanji - Welcome the jungle - (any scene where the games drums are playing)Solo - A Star Wars Story - The scene with the explosion of the train of coaxiumAvatarAny movie with low bass

Love these. My quality of life has improved just from having these. Installation was exactly what you would expect. I had no issues.
