Just listened to Billy Joel At Shea Stadium Blu-Ray on my pair of AMT 1-D's. The cymbals sounded like a real cymbals with nice bite and smooth decay. The drums sounded deep and, amazingly, didn't overhand by mid-bass bloat. I go a long time without listening to these and with a truly good recording they really still can impress me. Recordings with too much bass, especially sludge-like mid-bass bloat, sound bad no matter how good the mids and highs are.
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."
