The 141FCD compression driver is a high performance high frequency device ideal for professional loudspeaker systems. It’s core is designed based on our very 140FCD model. In fact the dome assembly is shared between these two models. The driver’s ferrite based magnetic circuit was modified to fit applications with a limited space and lower budget. Furthermore, we have added mounting adapter with 1 3/8” 18TPI thread to easy and fast mounting onto the horn throats that incorporate this thread. 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 105 dB 1watt / 1 meter.
