ESS Heil Air Motion Transformer AMT Tweeter Description
This is the original highly acclaimed ESS Heil Air Motion Transformer invented by Dr. Oskar Heil over 30 years ago. Unlike a normal piston loudspeaker that excites the air by alternately pushing and pulling a cone or dome, the Heil Air Motion Transformer linearly squeezes and expands its diaphram.
