181FCD

The 181FCDX8-227B is a 1.8-inch ferrite compression driver rated at 70 W AES (140 W continuous) into a nominal 8-ohm load - the highest power rating in the REDCATT 1.8-inch compression driver family. With a free-air resonance of 1,000 Hz, a 45.7 mm (1.8-inch) voice coil, and a 26 mm horn exit, this driver provides the extended low-frequency capability of the 1.8-inch format combined with very high sustained power handling. The large voice coil and robust ferrite motor are engineered for thermal stability under continuous professional drive levels, making this driver suited to fixed-installation and touring systems with demanding power budgets.

The driver's low Fs (1,000 Hz) allows horn loading from approximately 900 Hz, providing crossover flexibility below 1.5 kHz. In conjunction with the 70 W AES power rating, this makes the 181FCDX8-227B well suited to large-format 2-way PA systems where the compression driver must handle sustained high-power drive while operating at relatively low crossover frequencies. The 26 mm exit is compatible with standard 1.4-inch and 1.8-inch family horn designs.

The driver is rated for 70 W AES and requires high-power professional amplification. A crossover frequency of 1,000-1,800 Hz (18-24 dB/octave high-pass) is recommended to protect the driver below the horn-loaded operating range. The 8-ohm nominal impedance is compatible with standard professional PA amplifier output stages. Good to use with 15-inch or 18-inch professional woofers such as 15FINDX8-035, 15FPMX8-063, 18FINDX8-036, or 181XRX4-350 in high-power 2-way touring PA top and large-format system designs.

The 181FCDX8-227B is suited for 2-way PA top cabinets, high-power fixed-installation systems, and touring applications where the 1.8-inch format's extended low-frequency capability combined with the highest power handling in its class (70 W AES) provides maximum system performance headroom.
