Bodyshaker Speaker

These are great. We have a large Ikea Kivik sofa with a corner section. I originally made upnsome wooden spacers with bolts and screws to attach these to the frame, but ended up just popping them down the back of the seat cushion, under the back cushion. You can't feel the lump at all when sitting. I'm powering them off a 70W rms per channel car amp, fed from the LFE (or .1) pre-out on my yamaha receiver. The receiver sub out has an 80Hz crossover, and the amp a 50Hz Low pass filter. This works great for my setup, and can shake the whole sofa, to the point that the floor shakes when turned up loud. I am only using them for movies, and they stay pretty cool, but beware they get pretty hot when used for bass-heavy music - you have been warned! Update: some 3 years of constant use (well, a few hours of TV a night) and the original 2 are still going strong. Movies just aren't the same without these.

These do work quite well on sim vibe and for the price compared to others on the market they seemed good value which is why I purchased them. Maybe there are better ones out there but you will have to pay more for them.

If you want a effect like a rumble pack from your gamepad in your chair then look no further. One is fine for office chair, i have two in my two seater sofa (one at each end) but now have ordered a third for the middle. I honestly thought this would be a gimmic, especially running from an old 5.1 home cinema amp subwoofer out. Obviously i dont have any other speakers plugged in as i have to run it with high volume for them to work (please note running them like this they run a bit like a subwoofer in the respect that i do get sound coming through, but the volume is low compared to the feeling you get. On a side note i have a hdmi swith with optical out connected to a headphone amplifer which connects to the headphone socket of my cinema amp. Probably not the most efficient way to make it work, but this was old tech i had lying around. Pit it like this i refuse to play my racing games like f1 2015 on ps4 without this turned on anymore.

Kind of disappointed in these, because I was hoping for 100W of shaking, not 100W of heat and some shaking. That was probably unrealistic, but these do get excessively hot (over 100 degrees C) when run hard. Probably directly under your seat it would be fine (for racing games, etc), but I was trying to build a vibrating table. I overestimated how powerful these were. I ran them in first with a lower power and 30Hz sine wave for some time (some smell came off, and smoke/vapour from one of them, but it kept working). Then I tried increasing the power to get the level I was hoping for. Running 4 of them with a Europower EP2000, they got so hot they melted their own glue, and the yellow part came detached on two of them (I pressed it back in). Also the plastic part with the connectors started to bend. So if you want to run them close to their limits, then monitoring the temperature seems a reasonable approach. Maybe I need 8 of them, or maybe something else entirely. I wonder whether there's a way of measuring how much power or force is actually being delivered as vibration? That would perhaps help compare with other shakers. Update: For those who want to mod their shakers, here are some notes. The construction is pretty solid. The outside contains the coil and the inside moving part is magnetic. The inner part is held together with a steel pin through the centre. You can drill out one end and pull the pin out from the other end (make sure to tape over the gaps top/bottom to avoid shavings getting stuck to the magnetic parts inside). The inner part is also glued, so it won't fall apart on removing the pin. Now you can put a bolt through and some washers, and attach a heavier weight or whatever. Instead of a heavier weight, I tried attaching it to a floor plate to see if I could get my shaking platform to work better that way. However 4 bodyshakers aren't enough to lift my whole bodyweight even for a fraction of a second at 30Hz, so no vibration is felt at all that way. So it seems better to let them run with a free weight.

Screwed this into some scrap pine then that to the frame of my comfy leather 3 seater. Gives adequate fill to the sub woofer effect in all 3 seats. Really feels like the sub is louder than it actually is because of the psychological effect of feeling the bass. Gun shots and explosions are the obvious things that are enhanced but so is the effect of background noise and car engines, etc. I'm running this off the super bass output of this amp: ESYNIC Mini Hi-Fi 2.1 Audio Power Digital Stereo Amplifier Amp - Aluminum Alloy Solid Case and Easy to Distribute The Heat - Super Bass for CD MP3 MP4 https://www.amazon.co.uk/dp/B00WS5FOAQ/ref=cm_sw_r_cp_apip_oszZTALEyMAWg I'm considering ordering 3 more and running them of a 4 channel car amp. Just to give some extra effect at really low frequencies.

It just works, all you need is an amp to power it and you're good to go. Enhances your movies and gaming experience giving things a tactile feel. Doesn't come with any instructions or extra wires, etc, what you see in the picture is exactly what you get and nothing more. But it's easy enough to setup, if you have even basic experience in setting up speakers to an amp, you'll figure it out pretty quickly - from unboxing to working took about 5 minutes, you'll spend longer attaching it to whatever surface you wish to attach it to.

I ordered a pair of these for the chairs in my home cinema setup. Running them from a dedicated amplifier they produced a very limited effect even at full volume and get very hot when dealing with a sustained rumble. Due to some imperfections in the metal mounting ring they were also hard to get to mount perfectly flat.

I've only written one other review in what has to be close to a decade of being an Amazon customer. But I had to write how much value you get for your money. I've purchased 7 of these now for the purpose of adding tactile feedback to my sim rig and even just two of these will shake your rig quite a lot. However they get hot if you work them to hard, so it would be wise to get 4+. A slight issue that I've had with a few of these is that the bottom of the transducer can separate from the metal casing depending on how well each transducer is made. I've used gorilla glue to glue them back together and I've had no issues with them separating since.

Ce produit est certes très spartiate dans sa présentation. Il faut savoir pourquoi on l'achète mais c'est comme un subwoofer: a part l'impédance et la puissance il n'y a pas besoin de beaucoup d'autres infos. Je voulais installer un système style ButtKicker dans mon canapé mais je n'avais pas envie de mettre 200€ pour cela. J'ai donc pris un ampli 2*50W avec sortie subwoofer (on en trouve sur Amazon pour environ 20€, attention vous aurez besoin d'une alimentation de laptop 19-24V 3-4A !) et connecté l'article à la sortie sub. Ça fonctionne du tonnerre. Je ne peux pas fixer le shaker dans le bois du canapé donc j'ai recyclé un vieux caisson de subwoofer pour le glisser dans la doublure. Les vibrations sont assez impressionnantes, et ça ne fait pratiquement aucun bruit (ce n'est pas une membrane qui produit du son!). Idéalement sur un ordinateur, il faut utiliser un programme de mixage pour pouvoir rediriger le son vers diverses sorties (bluetooth, HDMI, aux, casque Rift si vous en avez un) et appliquer un filtre EQ sur la sortie du shaker. Le programme VoiceMeeter Banana fonctionne à merveille pour cela. Avec tout ceci pour moins de 50€ vous avez l'équivalent d'un ButtKicker... Je suis très satisfait, reste à voir la durabilité du shaker.

Używany do fotela Playset w simracingu. Drgania super. Mała wada. Niedokładnie przyklejona membrana. Ale trochę kleju epoxy i wszystko gra.

Llevo ya un par de años con tres de estos y funcionan como el primer dia en mi simulador

Habe mir dieses günstige teil bestellt um es einfach mal auszuprobieren.Ich bin Positiv überrascht in dieser Preisklasse. Habe es mir in mein Zweier Sofa eingebaut und das ding Bebt schon manchmal fast zu sehr, aber nur fast. Man sollte sich schon etwas gedanken machen wie und wo man es verbaut um einen guten Effekt zu erziehlen. Man kann nicht bestimmen von wo das rütteln ausgeht und macht deshalb öffters mal überraschte Gesichter von freunden die auf mein Sofa platz nehmen. Klar ist das Gerät mit 100 Watt nicht sehr hoch belastbar aber wenn man erstmal weis wo die grenze ist und nicht darüber hinaus geht hat man einen wirklich druckvollen Effekt der für mein kleines Sofa mehr als ausreichend ist. An der verarbeitung ist nichts auszusetzen. Druckvoll und mit wenig Aufwand zu betreiben weil einen alten aktiv Subwoofer hat doch fast jeder noch rum zu stehen. Man sollte schon darauf achten den pegel schnell regeln zu können um das ding nicht gleich durchs sofa zu Schießen. Macht mir viel freude und ich würde es wieder kaufen und empfehlen.

Jodå, den skakar om det mesta. Kul och rätt häftigt
