An Essential Maintenance Part in the B&C Speakers Ecosystem
The B&C MMD0128 fits within the brand's "pro-audio" philosophy: offering reliable replacement components to extend the lifespan of compression drivers. It is the recommended solution when your DE 12 has lost brightness, definition, or after an incident (overload, feedback, unwanted signal).
For Whom and In What Applications?
This replacement diaphragm is intended for technicians, rental companies, installers, and musicians equipped with sound reinforcement speakers using a B&C DE 12. It is ideal for refurbishing a sound system (stage monitors, front of house, fixed installation) without replacing the entire driver, while restoring a clean and articulate high-frequency response.
Reliability and Compatibility: The Essentials, Without Compromise
With a 25mm voice coil and a Mylar diaphragm, the MMD0128 is designed to restore the original behavior of the driver: precise attack, good intelligibility, and consistent response. By choosing a strictly compatible reference, you ensure secure installation and avoid performance or tonal deviations caused by incompatible parts.
