Borrowing the Air Motion Transformer (AMT) technology of the ESS Heil tweeter with a high quality replaceable cone, the Dayton Audio offers with its AMT-1 a superb high-end tweeter at a reduced price.

Also known as an aerostriction tweeter, the AMT concept uses a pleated Kapton diaphragm immersed in a constant magnetic field so that the pleats tighten and expand with the audio signal, pushing air out of them forward as the pleats contract. The result is an incredibly accurate tweeter, capable of maintaining high efficiency with ultra-low distortion for incredibly smooth and crisp highs at any volume level.
