Puck Tactile Transducer Mini Bass Shaker Audio Transducer Turn Any Surface into a Speaker

Surprisingly efficient for its size. I mounted it to a plaster wall and it is really happy there and modulates the whole wall which is about 9 x 10 feet.

The product itself has been great, it works perfectly as a bass shaker for sim racing or adding tactile feedback to other games as well. Another review on this product has said it outputs bass as well as all the other audio and may not be good for gaming, and this is a bit misleading. You need to have a program such as simhub linked for racing games that will use the in-game telemetry data to actually output nothing but bass (low frequency effects) aka LFE. If you're playing a game that doesn't have telemetry data you need to run a program like voicemeeter banana to apply a lowpass filter to the shaker that will only transmit from 0 to around 42hz. This applies to most if not all bass shaker products, not just these.My major problem with the purchase is the EXCEPTIONALLY misleading advertising done by SAMTRONIC by showing two shaker units in the first picture that comes up as well as the price per unit indicated at around 9.50 per unit on the advertisement. If I would have any idea that they were only sending one unit I would have NEVER purchased this and went with a much more reputable brand such as dayton audio or others for the same price. Amazon assured me they would send another unit at no charge because it was 100% false advertisement that they were allowing (and still are). Three months later they have charged me for the second unit that was supposed to be sent to make the purchase acceptable and as advertised.
