• Very high efficiency
• Powerful neodymium magnet structure
• Low mass folded aluminum diaphragm
• High resolution, defined sound characteristic
• Superb time domain and impulse response thanks to low energy storage

Aurum Cantus AST (Aero Striction Tweeter) 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 Aurum Cantus AST30130 Aero Striction tweeter is in a class of its own.
