Beyma introduced last year a new type of component for the professional sound, bringing the highest sonorous quality of the most demanding audiophile to the world of live music. This type of high frequency transducer is based on the AMT technology (Air Motion Transformer). In this type of transducers, invented by the German physicist and Nobel Prize Oskar Heil, the generation of the sound takes place in a very different from the habitual one in ribbon tweeters.

The advantages of this type of tweeter can be summarized in: 

- Radiation surface four times the one of a tweeter or an equivalent compression driver, thanks to its folded geometry. 
- Mobility transformer of air (Air Motion Transformer) because it causes in the air a speed four times greater than the one of the folds themselves (relation 4:1). 
- This confers an enormous dynamics and an incredible transient response, vastly superior to that of any conventional tweeter, including ribbon tweeters and compression drivers.
