The 075NCD compression driver is a high performance, high frequency device ideal for professional loudspeaker systems, high output hi-fi systems and after market car audio applications. The driver’s neodymium based magnetic circuit provides a robust, high force BL field, providing precision control of the Polyimide diaphragm assembly. The unit delivers the frequency response and high power handling through 0.75 inch exit throat. Diaphragm Assembly The driver features a 19mm Polyimide diaphragm formed as single piece with Polyimide suspension. The dome is carefully attached to a high temperature Kapton voice coil former that withstands the long term power characteristics typically seen in professional applications. The acoustic output exits through a bullet phase plug and a 0.75 inch throat aperture. Nominal sensitivity is 109 dB 1watt / 1 meter.
