RCF Diaphragm for CX10N251 – Replacement HF Diaphragm

Genuine RCF replacement HF diaphragm for the CX10N251 10″ coaxial neodymium transducer. The CX10N251 uses a 1.75″ dome compression driver loaded onto a 60° conical waveguide as its high-frequency section, and this diaphragm restores the HF output of the coaxial driver to factory specification.

The diaphragm and voice coil assembly is precision-formed and pre-aligned for drop-in fitment, preserving the original frequency response, sensitivity and dispersion. Using a genuine RCF spare maintains the tonal balance of the host cabinet (e.g. monitors and compact two-way reflex enclosures using the CX10N251) and any remaining warranty.

Replacement should be carried out by a qualified technician in a clean, dust-free workspace following the official RCF service procedure. Inspect the magnetic gap for debris before reassembly.
