MATERIALS
•   Diaphragm:  aluminium.
•   Voice coil: edgewound aluminium ribbon wire.
•   Voice coil former: kapton.                                Notes:
•   Magnet: neodymium.                                        *The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer’s ability to handle normal music program material.
**Sensitivity was measured at 1 m distance, on axis, with 1 w input, averaged in the range 1-7 kHz.
GENERAL DESCRIPTION
This high frequency compression driver features a composite structure diaphragm. It has a Mylar surround to provide damping and
avoid resonant peaks typical of metal surrounds. The dome is made of pure aluminium, with its unique mechanical properties.
This diaphragm combined with a new optimized phasing-plug and a copper ring, results in an extremely smoothed and extended high
frequency response.
