Monacor High-End Air Motion High Power, 20 W, 4 O

Air Motion Transformers are a special type of high-frequency speaker systems developed by the German physicist Oskar Heil during his research on the characteristics of human hearing. The main feature is a unique folding of the membrane film and its accordion-like oscillation when a sound signal is applied. This folding allows for a very large membrane area to be accommodated in a compact space. AMTs are characterized by a very dynamic sound image, excellent impulse response, high efficiency, and low harmonic distortion. For the AIRMT-130, two STL files for 3D printing wave guides are available.
