Description: Surface transducers give you the awesome power to turn almost any surface into a speaker. They’re essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. Hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound).

This guy is great, I wish it came with mounting holes for the head though. The head or “cone” unscrews, I had to drill a couple holes into this to mount it to my downhill helmet. This guy can take quite a bit of power, and if you mount it to your head via helmet like I did, it WILL shake your eyeballs to the bassier songs when the volume is turned up. I simply adjusted the EQ on my phone output and that problem went away. It is a little heavy on my head, and the steel spider is vulnerable if you crash, and near impossible to fix, so I don’t suggest using this as a helmet speaker for mountain biking. I still use it on my helmet, but I’ve got lighter, lower profile ones from Dayton Audio ready for a future implementation when I crash and ruin this last one I have.
Works great on posterboard as a speaker, and even better on honeycomb aluminum board. This is where it shines, permanently mount it to a “cone” and the body itself can screw into a hole - not sure what thread sizing it is - no datasheet info on that, would be great for a wall installation imo.
