AKG 2230M09010 - Capsule for C451B (Membrane, complete)

AKG 2230M09010 - Complete diaphragm for the C451 B microphone capsule

The AKG 2230M09010 is the original complete membrane that forms part of the AKG C451 B condenser microphone capsule assembly. Identified in the service manual parts list as Membrane, complete (position 7 ), this OEM reference replaces the diaphragm/membrane holder element responsible for the acoustic-electric conversion of the C451 B, maintaining its response and noise level according to factory specifications. It is the replacement indicated by AKG when the capsule requires rebuilding due to wear, contamination or physical damage to the plate.

For proper cartridge repair, AKG documents the following parts combination: 2230M09010 (complete membrane), 2895M06010 (complete electrode), and 2230Z28010 (insulating sleeve). The official service procedure also details handling precautions: the membrane sits freely within the cartridge lid and its surface must not be touched. It is recommended that qualified personnel perform the repair to avoid irreversible damage.
