The 140FCD is a very high performance device ideal for professional loudspeaker systems. 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. 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. Our voice coil to dome bonding is unique process, developed to greatly improve the power handling capabilities. REDCATT precise adhesives dispensing, combined with our.
