RCF Diaphragm for ND350 / CD350 – 8 Ohm Replacement

Genuine RCF replacement diaphragm for the ND350 (neodymium) and CD350 (ferrite) high-frequency compression drivers, 8 ohm version. The ND350 / CD350 is a 1.75″ diaphragm compression driver with 1″ exit throat used in many RCF cabinets including ART, NX and TT series two-way systems.

The diaphragm is precision-formed from Mylar with a Kapton-former voice coil and rectangular-profile copper-clad aluminium wire, assembled using specially formulated adhesives for high temperature and power handling. Pre-aligned for drop-in fitment to fully restore the driver to original specification.

Installation should be carried out in a clean, dust-free workspace by a qualified technician following the official RCF service procedure. Inspect the magnetic gap for debris before reassembly. Genuine RCF spares preserve the cabinet warranty and tuned acoustic performance.
