Harwood Acoustics AM 25.2 Air Motion Transformer
(AMT tweeter from Referenz kit)

This Harwood Acoustics AM 25.2 Air Motion Tweeter is 8 Ohm and pneumatic transducers utilize a special flexible low-mass aluminum diaphragm that is carefully folded and then suspended in a highly saturated magnetic field. Source sounds are reproduced by the compression/expansion action of the diaphragm, resulting in incredibly instantaneous, accurate response. Highly efficient yet refreshingly honest, the AM 25.2 Air Motion tweeter is in a class of its own.
