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 I originally made upnsome wooden spacers with bolts and screws to attach these to the frame, but ended up just popping them down the back of the seat cushion, under the back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.

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 StereoAmplifier 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_oszZTALEyMAWgI'm considering ordering 3 more and running them of a 4 channel car amp. Just to give some extra effect at really low frequencies.

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.

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.

Gives an amazing experience with films and music! I mounted some on the sofa for films and when you turn off you really do miss it! Such a difference! Placed one under my bed pillow and with drum n bass or meditation music it's mind blowing!! I purchased this with a 20w Lepy amp and it is not powerful enough. It needs a 50w amp minimum (can't find one yet...!) Even with my 20w I managed to get them nice and warm, like other have stated. It has good mounting points, you just have to spend time finding the right place for the resonance. Speaking of resonance, this shaker can turn into a loud speaker with a lot of high sounds, so works best through a sub out or low pass. Remember you always need a amp to power these shakers. Have fun!

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.

Those yellow plastic circular springs are just edge-glued to the metal casing on both the the top and bottom. The glue obviously fails in a few months of use from all the vibration. Then the heavy core moves off-center and collides with / grinds against the casing and can get partially stuck = weak shakes and lots of heat.The price is great compared to the competition, and it is otherwise very functional up to the point of failure. But don't expect much durability from this very silly design.

I am using with as part of my SSF setup in my virtual pin and its fantastic value for money. The unit doesn't get warm and delivers plenty of punch (actually needed to turn down as too much). Think in this application hard to see why I would spend double if not triple price.
