Interesting. What exactly are they used for? I'm not sure I fully grasp the concept. Have you heard them?

Also, they seem so inexpensive, you might have trouble building them for that price.

Hello

You mount the speakers on any flat surface like a door or a table and the whole surface acts like a speaker...

I dont know how they sound...

Yes, I read the little snippit on them in the link. I'm just not sure whether these are a good idea or if a little too much red wine was consumed during their inception. Now if this were simply a woofer motor (read "bass shaker") used for augmenting the bass of some small satellites, well then there's a litlle more sense to them. I'm just not in on the theory.

they are probebly for low frequentie use only. I don't think the will produce 16khz or higher...

Most people can't hear above 16KHz anyway, so what's the problem!

Interesting idea...but i'm willing to bet it will make the best recording sound like an FM radio with a pillow placed on top of it.

BES panel speakers used this concept well. They were planel speakers that used a sheet of styrofoam about 1/2" thick about 2'x 3' for the bass and 2' x 1' for the mids, Cone tweeter. They had the driver hooked to the panel via glue and the back of t he driver was mounted to a thin almum frame. I used these for many year before selling them and making my First DIY's. They imageing on them was fantsic but they were pwr hungry(lot of mass to move) other than that great speakers.

It is an NXT style transducer. Just a VC in a small carrier, AFAIK. These are actually interesting devices, while they work with any placement on thin surfaces, there are probably a few locations that work better than others. They work by exciting the entire surface they are attached to.

It is not some revolutionary technology - there hasn't been a real innovation in speakers in many years and almost everything you read on the net about various designs is just advertising hyperbole. Even the best ideas always involve tradeoffs.
