Dayton AudioTT25-16 Puck Tactile Transducer Mini Bass Shaker 16 Ohm

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!

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.
