ESS Heil 1107 AMT-1 Replacement Tweeter Diaphragm
Genuine replacement diaphragms for many ESS Heil Air Motion Transformers, past and present. Easy to install—AMT performance is quickly restored to new! The ESS Air Motion Transformer (AMT) uses a folded pleated Mylar diaphragm of a mere 0.0005" thickness! Because the moving mass of the AMT is extremely low and the magnetic structure very powerful, this combination results in extremely high acceleration that yields amazing transients. ESS manufactures the original and still best Air Motion Transformer invented by Dr. Oskar Heil over 30 years ago. Mfg. #1107: fits AMT1A, AMT1B, AMT1C, AMT1D, and many more. Dimensions: 5-9/16" H x 1-9/16" W.
