ESS HEIL II-Pair
Heil Air Motion Transformer
The Heil diaphragm, made of soft, quiet mylar to reduce background noise, is bonded with conductive aluminum strips. It is the equivalent in surface area to a conventional cone-type eight-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.
