Beyma SMC-60 80W 8 Ohm 2" Bolt On Compression Driver
This 2" professional high quality compression driver features a composite diaphragm assembly. The mylar surround provides damping and avoids the resonant peaks typical of metal surrounds. 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. The use of a rim centred diaphragm allows field replacement without soldering.
