Dayton Audio TT25-8 Puck Tactile Transducer Mini Bass Shaker 8 Ohm

This was a very cheap way for me to add some depth to my home theater system. I moved my subwoofer to another stereo in the house because the fronts on my surround system can reach pretty low and I didn't think I'd miss it. But then I missed it. I could still hear a good amount of bass in general but some of the feel of it was gone. Movies and music got a little more remote. I don't care for a carnival ride of rumbling for every deep note in a movie or music but I like it to be hyper-realistic and immersive. I realized I had an old receiver sitting in a closet and I could run one of these bass shakers with it through the subwoofer out on my ht receiver. And it works great. For a while I had it bolted to the bottom of the couch. At times it just seems like the sounds you're hearing are also shaking the room and it really gives the impression of being louder without actually being louder. Immersive. Cool. But other times it's just a simple thing like a character closing a door and the thing wiggles your butt. Pretty distracting and dumb. So I attached it to a big plywood panel on a bar that is right behind the couch. The couch is pushed right up against the bar. So what happens is the plywood is acting as an exciter speaker to some degree and you can actually hear the bass the shaker is producing. And it shakes the couch in a more passive, subtle way that is very realistic. It was just lucky that I have this bar behind the couch and this works so well but the upshot is that I made my system sound better and feel better for only 16 bucks. And it was fun experimenting with different placements. Now I'm getting ideas for using a large, suspended panel of plywood to try to create a free-standing subwoofer in the room. Just for kicks.

Works better than the 25w generic transducer. Just get this and pair with the nobsound amp.

I bought two of these because I could never give my system a work out. I have always lived in pretty close proximity to others with paper thin walls. While my existing sound system only pushes 18watts to the sub-woofer these units solved the issues I had with cutting out the low end of my sound system so as not to disturb the neighbors and room mates. If you've done your research on these, or shakers in general, I can confirm the hype that they immensely improve your listening experience to movies music and gaming. They are not very big but they make a world of difference when listening to content with a vibrant soundscape in the low end. They aren't perfect but they are impressive for the price range. Technical and instillation- as you can see from the image these have pretty small leads, I belive its about 6”. they are also not very thick so putting to much stress on them could result in pulling the leads straight out of the houseing. Make sure you wire them correctly the first time or you could quickly run out of slack leads. These should also be considered low end pro units. The instructions that come with these are pretty sparing but they recommend that you drill out a hole in what ever surface you are mounting them to. While these units can be pretty robust and rugged if you don't heed the instructions on this point you risk damaging the shakers. Restricting the movement or burying your units will shorten their lifespan. While they don't get very hot- they do need airflow, while they are designed to shake the object they are mounted to- they do need their full range of motion when they are permanently mounted. I've seen people reviewing these on Youtube who just screwed them to the bottom of office chairs and I would not recommend that. While it would give you an extra kick for a while eventually the lack of range would either limit the output (audio range) or damage the units over time. Admittedly its not practical to get a hole saw and carve out divots in the bottom of an office chair it is practical to hit the hardware store and get a few pieces of scrap 2x6 to do the job and more than likely they'll be free. Furthermore, as has already been mentioned, the leads are pretty short and thin. When you install this to an object you should make sure to include adequate slack in your wires and possibly a quick release. I accomplished this by getting some RCA extension cables from GoodWill and just patching the sockets to the ends of my wires. Most consumer sound systems do not support external sub-woofers. If you have a decent 2.1 or higher system then these will work fine for you. The important part is to be aware of the resistance of both the shakers you are installing and the resistance of your existing driver (listed here in Ohms, this product specifically 8ohm). My system has a 4ohm driver so I had to wire my units in parallel so they would work correctly. If you do not respect this you could damage either the shakers or your sound system. You could hypotheticaly still use your driver along side your shakers but expect a performance ding from doing so. In much the same way as you can wire an 8ohm 10watt speaker to a 4ohm 4watt channel you will get much quieter audio because of differences in voltage and resistance. I would also recommend taking the time to wire up your shakers “non-permanently” with some sort of quick release. I used my Goodwill connectors to route the lines to my sub-woofer outside my speaker box so I could chose either my shakers or my driver at any given time. If you have the experience or the time you could create a circuit that toggles between your inbuilt driver or your shakers but I opted for the manual approach. The TL;DR of this review is that I am very impressed with these little pucks. They are quite small and very much worth the money. I opted for 2, not that I had much choice knowing the specs of my sound system, and they are very affordable. I did the research on these units, and while instillation instructions where hard to find the rave reviews can be confirmed. They take a mediocre sound system and make it awesome. It changes a loud sound system that keeps your neighbors awake to a personal experience for you only. If you aren't afraid of wiring something up yourself I would highly recommend buying these!

These transducers are great! They add another dimension to my home theater and really make my subwoofer sound more powerful without shaking the whole house. I have one attached to each of the four chairs in my sectional. They have no low pass filtering, so they will produce whatever noise is thrown at them, albeit in very low quality for the higher tones. As a result, you need to use the subwoofer output from your receiver, or add a low pass filter before it gets to the device. The wires coming out of the transducer are somewhat thin and the leads are very short. Quality control can be hit-or-miss. I purchased 4, but had to send back 2 in the process. The defective ones made strange noises when driven with a low frequency sine wave, but only when placed vertically. Clearly something was loose inside. Amazon was painless in making the exchange. While seeming simple, they weren’t the easiest to set up. The first thing I noticed when I received one was that the instructions tell you to install it in the mounting bracket, separately purchased of course. I made my own mounts. Using 1 inch mdf, I cut out a circle with a hole saw for the base of the transducer. I cut an additional hole to allow the wires to move freely without being pinched. After mounting the transducer to the home-made plate, I mounted the plate to the base of each chair. I used crimp connectors to attach the wires to some standard speaker wire, which I then ran to the amp. The amp I used was the DROK Micro TDA7377 DC12V Digital Audio Power Amplifier. It’s very cheap and 35 watts/channel. It doesn’t come with a housing or power supply, but I figure that gives me more options. I simply mounted it to a board I had laying around and powered it with the Chanzon 12V 5A 60W AC DC Power Supply. Looking back, I probably would have gone with a 6A supply to cover the full power of the amp, but I don’t think I’ve ever maxed them out, and haven’t noticed any ill effects. When I expanded from 2 to 4 transducers, I added a second amp and power supply. Edit (10 month update): I have these transducers tuned so they hit at just the right time with the sub. If they are tuned too high, it feels unnatural. I've noticed that they seem to resonate stronger at a small frequency range (I haven't determined the exact frequency). It's possible that my chairs are the cause of the resonance, but my guess is the transducers. When you don't think about it, it's not an issue, but I would have liked a wider plateau in the frequency response.

I used these for a mediation chair. They are wonderful, and make my experience wonderful.

I attached two of these to the wood frame of my home theater couch using a small FOSI amplifier to power them. The input to the amplifier is split off of the LFE line of my receiver that also feeds my subwoofer. I was amazed at how much vibration I get out of them despite their small size and price. The first thing I noticed was they don't really respond to low audible bass notes in what you are listening to. There might be some vibration there, but it is subtle. They really kick in (pun intended) when you're playing a movie that has been obviously mixed with seat transducers in mind. I guess that would be the E in the LFE channel. I set the volume so they are really only felt when the film or TV show has an intentional effects sound in the mix. If you turn the volume up too much, the constant vibrations can be a bit distracting. You want them set to really only be noticeable when the filmmaker wants them to be. In general, when watching a non-action TV show or listening to music, there isn't much of a noticeable effect. There might be a little vibration in low notes, but it could be mistaken for just the sound of the speakers in the room vibrating the furniture. However, when watching a movie where there are intentional effects in the sound mix for transducers, it is quite obvious they are there. I guess they are more sensitive to the frequencies that are near the low end or below the typical range of hearing. One example where I noticed this is at the start of Star Wars IV, A New Hope in Atmos. During the opening scene, you can feel vibrations corresponding to the rebel ship being attacked. The low sounds that aren't that audible from the speakers, but you can definitely feel the vibration. You get the sensation that the Star Destroyer is latching onto the rebel ship.. Another good example of vibration is in eppisode 1 of The Last Of Us when a jet liner is crashing on a street. There is a very noticeable vibration corresponding to the jet exploding that will make the already tense scene more shocking. Other places The Last of Us uses the transducers is in scenes with gunshots. I'm very happy with these inexpensive transducers and the new element they have added to my home theater experience.

I consider myself a budget audiophile and my current gear consists of an Emotiva Processor, Multiple Emotiva Amps, Tannoy Precison 6.4 Speakers and 2 HSU Subwoofers. I have been interested in Tactile transducers for a while but never really owned one. Considering I primarily listen to music and have enough bass for my purpose in my system. However, lately due to conflicting work schedules, I am at times forced to watch a movie or listen to music via headphones. Headphones sound great but lack the feedback of a real subwoofer. So I decided to order a pair of tactile transducers. Like many of you I was unsure between the AuraSound and the Dayton transducers. So I ordered a pair of each. Ultimately, I ended up using both of them. Here are my observations 1) A decent tactile experience needs more than one transducer. 2) The AuraSound transducer is much larger and produces much more vibration than the dayton transducer 3) My butt can handle a lot more vibration than my head can. So, after a bit of experimenting, I decided to put the AuraSound ones at the bottom of my seat and the Dayton one behind the back. (Less vibrations in my head, more on my body). If you have an amplifier than can handle a 4 ohm load, buying the 8 ohm version of each and wiring them in parallel will work. Else, buying the 16 Ohm versions and wiring them in parallel will be the way to go. I tried a few different amplifiers on these transducers, and came to the conclusion that high end features of amps like THD, Signal/Noise ratio etc, doesnt make much difference in the over all experience of these transducers. As long as you have 20 watts or more of RMS power, you will do fine. The class D amps on sale here serve the purpose. In my case, I brought a cheap onkyo reciever from craigslist for $ 40 and added a subwoofer crossover to the output to filter out the higher frequences. (Crossed over at 80Hz). Removing the crossover creates a subtle difference, but if you have a subwoofer out that has a low pass filter built in, you may not need a crossover. As for the final effect, I didnt tell my wife that I had these in our couches. At first she thought the vibrations were from our subwoofer, but then came a scene in the movie that she remembers distinctly (a scary scene). And she literally jumped out of the seat. And the amusing part of this experience was, the subs were switched off. As some other reviewers have noted, these can make up for a decent experience without using a subwoofer. Like a gaming scenario or while listening through headphones. For music only, I prefer to switch these off. PS: These would make a good low pass crossover pair http://www.amazon.com/FMOD-Crossover-Pair-Low-Pass/dp/B0006N41DS/ref=pd_rhf_cr_s_cp_19_Q72F?ie=UTF8&refRID=1KK17M1J89KQJW1HYQFH

This is a great shaker for home cinema or gaming chairs. You should note that the effect is subtle, which is what I needed. The subtle low frequency shake really adds to the feel of action scenes and depth to my (compact) sub. If you want something to shake the popcorn off your lap then this won’t be right for you, but to add some drama during action scenes this is excellent. Things I like: it’s small size; low cost and; subtle (when used on its own) effect. Things I don’t like: You can’t mount it without drilling a cut out, it produces vibration above the stated 80hz frequency and it’s noisy when bottoming out from overdriving. You’ll want to find an amp with an 80hz crossover to stop frequencies above this feeding through your chair and you’ll have to be gentle with the volume control to avoid noisy bottoming out in loud scenes, but even with these limitations it’s a full 5 stars from me. I really don’t know why anyone would spend more!
