GENERAL DESCRIPTION                                         **Sensitivity was measured at 1 m distance, on axis, with 1 w input, averaged in the range 1-7 kHz.
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 titanium, 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.
