Accuton C90-6-079 陶瓷中音
.The C90 - 6 - 079 is a 5 inch midrange driver with ultra hard ceramic dome. Anti-resonant cutout fills in the ceramic dome provide for damping of the 8 kHz dome resonance. A FEA optimized overhung motor design with 38 mm aluminium voice coil former and ferrofluid filling guarantees excellent heat transfer. The low mass inverted fabric surround and a thin fabric spider center the moving parts with high linearity.As a typical home stereo midrange driver, we recommend our C90 - 6 - 079 for an application from 250 Hz – 5000 Hz.
