The Legendary Heil Air Motion Transformer is nothing less than Amazing! Bass is extraordinary, even at low volumes. The surrounds and passive radiators are all NEW! Original Owners manuals. Tech cleaned and inspected. Oak Veneer is presentable, look great at 3ft, but under close inspection could use a lift. Grills are original and decent (burgundy color). Auditions available. 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 diaphragm's pleats, moving the airload 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.
