He also invented the "air-motion transformer" audio speaker technology [6] made famous by the amt1 speaker of ESS in the early 1970s.[7]
The amt diaphragm is made of a mylar ribbon, bonded with conductive aluminum strips. It is equivalent in surface area to a conventional seven-inch cone type mid-range driver, but is accordion-folded down to a compact one and a half inch grouping for point-source dispersion. The low-mass diaphragm is suspended within a dipole magnetic field concentrating an intense field around said diaphragm. When signal current passes through the aluminum strips, the ensuing bellows-like motion of the folded pleats moves air five times faster than with a conventional cone driver. This rapid acceleration of air-motion is claimed to provide enhanced sound reproduction, including high dynamic range and over a broad frequency range.
