MATERIALS
•   Diaphragm: titanium.
•   Voice coil:  edgewound aluminium ribbon.
•   Voice coil former: polyimide.
•   Magnet: neodymium.                                        Notes:
*The power capacity is determined according to AES2-1984 (r2003) standard.
GENERAL DESCRIPTION                                         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.
This 2” professional high quality compression driver features a composite diaphragm assembly. The mylar surround provides damping and
avoids typical resonant peaks of metal surrounds. By the other hand, the pure titanium dome exhibits the unique mechanical properties of
this material. The diaphragm is attached to a 3” edgewound aluminium ribbon voice coil, providing exceptional high acoustic pressure over
an extremely wide frequency range. Moreover, the neodymium magnet reduces the net weight around a 50% with regard to a ferrite model.
Finally, the use of a rim centred diaphragm allows field replacement without soldering.
