ESS AMT 4
The ESS AMT 4, in clean, contemporary styling, is the compact, floor-standing system from ESS that employs a full, bi-polar radiating ESS Heil air-motion transformer midrange/tweeter assembly for the open imaging that gained the ESS AMT 1 international recognition.
The AMT 4's new dual magnetic plate transformer is identical in operation to the original ESS Heil air-motion transformer but is only two-thirds as high. It is slightly less complex in structure and is made up of two precision machined ferrous metal grilles energized by three pounds of strontium ferrite magnet material.
Every important characteristic that earned the original ESS Heil air-motion transformer acclaim throughout the world has been retained: incredible clarity and definition; instantaneous transient response; high efficiency; outstanding stereo dispersion; wide smooth response to beyond 20kHz; and the design simplicity that enables an ESS Heil air-motion transformer midrange/tweeter to carry a lifetime warranty to the original owner.
Designed with the idea that outstanding components are seen as well as heard, the ESS AMT 4 presents the fascination of simplicity with a flair that slips easily into any surroundings, while the wide dispersion characteristics of its drivers eliminate critical room placement problems.
Bass and lower midrange frequencies are produced by a high acceleration, ten-inch air suspension driver designed by ESS for outstandingly tight, clean bass coupled with clear and precise midrange definition.
The upper range is carried by the new dual magnetic plate ESS Heil air-motion transformer midrange/ tweeter that provides smooth, high-resolution clarity and unprecedented wide dispersion pattern to the very highest frequencies.
As is true with all ESS Heil air-motion transformers, it is completely free from the limitations present in even the most sophisticated paper-cone, voice coil, electromagnetic or electrostatic speakers.
The ESS AMT 4 is engineering so advanced, performance so outstanding, and styling so uncluttered, that its position of leadership and value will remain pre-eminent for years to come.
