Surface Transducer Turns Virtually Anything Into A Speaker

After removing the filter and the casing of the device (i.e. the white plastic) and mounting on a suitable surface these transducers really sing I used a 24 by 30 sheet of 1/8 inch birch plywood. This material is still a little too heavy for using as a NXT Speaker like device, but provides the bass many other materials lack. For each speaker 4 transducers + 1 cheap full range was used .the efficiency of the speaker is not high, but when suitably powered these can be very loud. For the 24 dollars spent on the speakers and 20 bucks for the materials these have proved to be some of the best <50 dollar speakers I have ever heard. One last thought, after these were stained, they look gorgeous and it s hard to think of anyone objecting to these being on display in a living room

Got this just because I was curious. It is kind of fun to see what would make it sound the best. It seems like it is not the feet that needs to be attached to the surface, but the body. Anyways, it sounds best attached to my plastic waste basket. I couldn't imagine using it for anything serious, but I am just a novice

I've installed these transducers in the ceiling throughout my kitchen and dining room and they work quite nicely. I wasn't so sure from the other reviews how well they'd work through drywall, but they work fairly well. At least, if you have enough of them anyhow. I ordered 8 pair (still only $40) and that did the trick.

I also removed the high pass filters since I wasn't sure how the combination of parallel and series wiring would affect them. I can't vouch for foam board or doors, but through drywall there is next to no bass response and I will be adding a (sub)woofer to fill in the lows.

Final note, have a few kinds of super glue on hand, because the first one I tried didn't work so well.
