The ESS AMT Speaker is available in stores and online. It has such a different look then any other speaker. The Heil diaphragm, made of soft, quiet mylar to reduce background noise, is bonded with conductive aluminum strips. It is equivalent in surface area to a conventional cone type eight inch midrange driver, but is accordion-folded down to a compact one-inch band for better point source
. dispersion. The low mass diaphragm is suspended in a massive magnet structure concentrating an intense magnetic field around the diaphragm. For more information, visit http://en.wikipedia.org/wiki/ESS_speakers
