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.There are 2 STL files available for the AIRMT-130 for 3D printed waveguides.;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;;Klang Ton 08,09/2016;“Compact AMT with quite a low crossover frequency possible for two-way speaker systems and multi-way speaker systems of highest quality.”
