141FCD

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 steel face-plate for easier assembly on production lines for high-volume productions.
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.

The 141FCDPX4-372 is a 1.4-inch ferrite compression driver rated at 30 W AES (60 W continuous) into a nominal 4-ohm load. Sensitivity is 105 dB (1 W/1 m). With a free-air resonance of 950 Hz and a 25.6 mm horn exit, this driver is closely related to the 141FCDPX4-337 and shares its wide operating bandwidth and low Fs advantage. The primary differentiator is the delivery format: the 372 is supplied with a steel mounting plate, providing a rigid, precision-located mounting interface for horn integration in demanding professional and touring applications where dimensional consistency and mechanical stability are required. The 4-ohm impedance and polymer diaphragm on a 35.6 mm voice coil match the 337 in electrical and thermal performance.

The frequency response is usable from approximately 850 Hz with horn loading, with a flat plateau of 102-106 dB maintained from approximately 1 kHz to 15 kHz, mirroring the broad usable bandwidth of the 337 variant. The very low Fs (950 Hz) allows crossover integration at frequencies approaching 1 kHz with appropriate high-pass filtering, making this driver suitable for system designs requiring a low mid-to-HF crossover point.

The driver is rated for 30 W AES into 4 ohms and is suited for professional touring and installation PA systems. A crossover frequency of 1,000-1,500 Hz (18-24 dB/octave high-pass) is recommended. The steel mounting plate simplifies repeatable horn alignment in manufactured cabinet designs. Good to use with 12-15-inch professional woofers such as 12NPMX8-054, 15NPWX8-016, 15FPMX8-063, or 15FINDX8-035 in 2-way high-efficiency PA top designs.

The 141FCDPX4-372 is suited for 2-way PA top cabinets, portable column PA systems, and commercial installation products where the low Fs (950 Hz), 4-ohm impedance, 30 W AES power handling, and steel mounting plate are required for professional-grade horn system integration.
