RCF ND 850-1.4

RCF N850
The N850 is a high quality 3.0-inch diaphragm compression driver with a 2 inch exit.

The diaphragm is precision formed from .05 mm thick pure titanium. The suspension is based on a Mylar vented design. The front aluminum adaptor guarantee a very smooth transition from the phase plug to the 2” output interface.

Applications
The N850 is a compression driver for professional applications, from high power 2-way systems to multiple-way long throw systems and large format arrays. Very good linearity and efficiency in combination with RCF H6040 horn (60 X 40 degrees dispersion).
