Product Details

Dayton Audio AMT1-4 Air Motion Transformer Tweeter

Borrowing technology from the original ESS Heil Air Motion Transformer (AMT), plus a high-quality replaceable diaphragm, the Dayton Audio AMT1-4 makes a superb high-end tweeter available at a supremely attractive price.

Also referred to as aero-striction tweeters, the AMT concept uses a pleated Kapton diaphragm immersed in a consistent magnetic field so that the pleats constrict and expand with the musical signal, pushing the air out from between them in the forward direction when the pleats contract. The result is a tweeter that is incredibly accurate and immediate, and capable of sustained high output with ultra-low distortion for sensationally smooth, clean treble at any volume level. Recommended minimum crossover frequency of 2,500 Hz at 12 dB/octave.
