The C90-6-079 is a midrange drive unit featuring an ultra hard ceramic (Sapphire) 90mm diaphragm in a 130mm square chassis. This unit is based on the C90-6-078 and features a revised suspension / inverted fabric surround with ferrofluid cooling of the voicecoil ; this results in a smoother low end response and slightly lower efficiency.

The diaphragm profile is quite shallow and essentially is best viewed as a large inverted dome with the dispersion advantages of such. Precision cut apertures provide critical damping of the 8 kHz resonance.

An  FEA optimized overhung motor design with 38 mm Aluminium voice coil former guarantees low energy storage and excellent heat transfer.

We recommend an application from 250 Hz – 5000 Hz.
