ZXPC Replacement Diaphragm for B&C DE750 Series - Titanium Voice

In this review the ZXPC Replacement Diaphragm is assessed for technicians and audio enthusiasts who need a direct-fit diaphragm for B&C DE75/DE750/DE82/DE85 series and compatible drivers like EAW CD-5001. The bottom line: this is a straightforward, titanium diaphragm replacement that restores output and maintains performance for 8 ohm compression drivers; the single biggest reason to buy is its accurate dimensional match to the originals, making swapouts quick and reliable when the printed specs and photos align with your driver.

Key Features

• Direct compatibility: Designed to fit B&C DE75-8, DE750-8, DE82, DE85 and related TN variants so installers avoid fitment surprises.
• Titanium diaphragm material: The titanium dome offers a balance of durability and clear high-frequency articulation for live and installed sound applications.
• Precise overall diameter: At 4.31 in overall diameter the part matches the physical envelope of original diaphragms for an accurate mechanical seal in the driver throat.
• Correct voice coil size: A 2.93 in voice coil diameter aligns with the specified coil geometry to preserve motor coupling and frequency response behavior.
• Standard impedance: The nominal 8 ohm rating ensures electrical compatibility with the original driver and existing crossover networks.
• Thin dome profile: With a diaphragm thickness of 0.05 mm and 13.5 mm height the profile mimics OEM geometry for reliable acoustic performance.

Who It's For

The ZXPC diaphragm is for sound technicians, PA repair shops, and home audio hobbyists who own compatible B&C and EAW compression drivers and need a like-for-like titanium replacement that keeps performance consistent. It is particularly useful when original diaphragms are damaged, allowing quick field or bench repairs without revoicing physical driver characteristics.

Those who should look elsewhere include users needing a different impedance, non-titanium dome materials, or custom revoicing beyond OEM geometry; also verify the pictured part and dimensions before purchase if your driver uses nonstandard assemblies or adapters.

Pros & Cons

Pros

• Accurate dimensional match reduces installation time and fitment issues during replacement.
• Titanium dome material provides durable high-frequency response suitable for PA and installed sound.
• Voice coil diameter and impedance match maintain the original driver electrical and mechanical behavior.

Cons

• Limited to specific B&C and compatible EAW models, so it is not a universal diaphragm solution.
• No customer text provided to confirm long-term reliability, so users should verify fit and initial performance on delivery.
