ZXPC Diaphragm Replacement for B&C DE750 Series - Titanium 16 Ohm

In this review the ZXPC Diaphragm Replacement is assessed as a focused repair part for technicians and owners who need a reliable titanium diaphragm for B&C and compatible high-frequency drivers. The bottom line: this part delivers a precise rebuild option with a true titanium dome, a 2.93 in voice coil diameter and a 16 ohm nominal impedance, so it is best for those restoring professional compression drivers or upgrading a worn diaphragm rather than casual tinkering.

Key Features

• Titanium diaphragm: Provides a stiff, lightweight radiating surface that preserves transient detail and high-frequency clarity when replacing a damaged dome.
• Exact diameters: The 4.31 in overall diameter and 2.93 in voice coil diameter match common B&C driver dimensions to simplify installation and alignment.
• 16 ohm nominal impedance: Matches the electrical requirements of 16 ohm DE-series and compatible drivers for predictable crossover behavior.
• 13.5 mm diaphragm height: Maintains correct excursion and gap spacing so the driver retains intended acoustic performance after rebuild.
• Direct compatibility list: Sold as compatible with B&C DE750-16, DE750TN, DE82, DE85 and EAW CD-5001, reducing the need to hunt for model-specific parts.

Who It's For

This diaphragm is aimed at audio technicians, rental house engineers, and DIYers who are comfortable performing speaker repairs on compression drivers and need a durable replacement that preserves the original mechanical geometry. The titanium material and specific dimensions make it suited for professional use where high-frequency response and reliability matter.

Those who should look elsewhere include casual home listeners without repair experience or anyone needing a different impedance or non-titanium materials; if your driver is not listed among the compatible models or uses an unusual mounting, confirm fit before purchasing.

Pros & Cons

Pros

• Precise mechanical match to common B&C DE-series drivers simplifies installation for rebuilds.
• Titanium diaphragm offers strong high-frequency performance and durability under heavy use.
• 16 ohm specification keeps crossover and system load predictable when replacing like-for-like.

Cons

• Compatibility is focused on specific DE and EAW models, so fit must be verified for other drivers.
• Installation requires careful alignment and basic servicing skills; not a plug-and-play upgrade for novices.
