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.
High-end Air Motion Transformer tweeter, 20 W, 4 Ω

  • 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
