Original ESS Heil Air Motion Transformer™ I - LARGENEW! PAIR in Original Boxes Invented by the noted physicist and scientist, Dr. Oskar Heil, the ESS Heil Air Motion Transformer (AMT) tweeter uses a folded pleated Mylar diaphragm just 0.0005 thick. Its voice coil is a serpentine pattern of precision-etched aluminum, selected for minimal weight and high power handling.Unlike a normal piston loudspeaker that excites the air by alternately pushing and pulling a cone or dome, the Heil AMT Air Motion Transformer linearly squeezes and expands its diaphragms pleats, moving the air load at a very high velocity. Because the moving mass of the Air Motion Transformer is extremely low and the magnetic structure very powerful, this combination results in extremely high acceleration that yields amazing transients.
