Description

Air Motion Transformers are a special type of tweeter systems which have been developed by the German physicist Oskar Heil during his research on the characteristics of the human ear. The main feature is a film-covered cone with a special folding which vibrates like an accordion when an audio signal is applied. This folding allows to accommodate a large cone area at a minimum of space. The AMTs feature a dynamic sound, an excellent transient response, a high efficiency and a low harmonic distortion. Tweeter based on the principle of Air Motion Transformer

  • High-performance neodymium magnet system
  • Fine, dynamic and brilliant reproduction of the high frequencies
  • Folded cone made of Kapton and aluminium
  • High efficiency
  • For use from 2,500 Hz on
  • Robust aluminium front panel
