Beyma CP755TI

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.
