ESS and Heil air-motion tranformer - any thoughts?

These seem like interesting speakers, has anyone on this board had any experience with the ESS line of speakers?

A.M.T. description:

"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.

When a signal passes through the aluminum strips, the bellows-like motion of the folded "pleats" squeezes air out five times faster then the air motion of a conventional cone driver. The virtual "instant acceleration" provides high definition, crisp transients, and overall spaciousness with superb dynamic range. This type of performance distinguishes the heil from all other transducers."

I've always wondered why the AMT design did not get more attention over the years,with more designs showing them.Maybe a legal thing?

I owned the AMT Rock Monitors back in the early seventies.Sheesh,could these rock out,and with detail to spare.Those were interesting times.

No speaker of the time could do the Doobie Brothers with such dynamic aplomb and airy detail,but of course the fact that my pals were actually "doing doobies" in my room could have affected my senses -:)

Best to all
