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 AssemblyThe 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.
