>>billson: this is essentially what we call an electro static speaker. and that means it works by converting electrical voltage to sound. a conventional loudspeaker, one of these, converts electrical current to sound. now this as you can see is relatively small which means that sound goes off in all directions. because this is a relatively large area, and all the sound resonates at the same phase & frequency, this means it's a lot more directional than conventional speakers >>reporter: this material can't produce bass level frequencies at the moment, so it could only really replace your tweeters. it'll also need to be driven by a different kind of amp but on the plus side the high voltage/low current nature of the system means it will use a lot less power than traditional speakers. and with clear directional sound that isn't being boomed out from a central stack, there are implications for this technology in lots of markets - from rock concerts it might have a small footprint, but it's creators have big hopes for it's potential in a global speaker market
