Redcatt 140FCDX4 4 ohm 1,4 inch tweeter

The 140FCD compression driver is a very high performance high frequency device ideal for professional loudspeaker systems. The driver’s ferrite based mag- netic circuit provides a robust, high force BL Ƃeld, providing precision control of the Polyimide diaphragm assembly. The unit delivers extended frequency response and high power handling through 1.0inch exit throat. REDCATT has developed unique motor system magnetic gap volume tuning This feature dramatically improves THD and improves the transient response of the driver.

Diaphragm Assembly The driver features a 36mm Polyimide diaphragm formed as single piece with Polyimide suspension. The suspension has designed and FEM optimized venting features to lover the harmonic distortion. The dome is carefully attached to a high temperature Nomex voice coil former that withstands the long term power characteristics typically seen in professional applications. The acoustic output exits through a radial phase plug and a 1.0 inch throat aperture. Nominal sensitivity is 110.5 dB 1watt / 1 meter. REDCATT uses state of the art adhesives in all assembly steps. Our voice coil to dome bonding is unique process, developed to greatly improve the power handling capabilities. REDCATT unique and precise adhesives dispensing, combined with our in-house developed dome treatments are further improving the long term reliability of this product.
