ZXPC Diaphragm Replacement for Yorkville 7461 7573 Driver - Reliable

In this review of the ZXPC Diaphragm Replacement for Yorkville 7461 and 7573 driver tweeters the bottom line is simple: this is a straightforward, no-frills HF diaphragm intended for technicians and hobbyists who need a direct-fit replacement. The reviewer found it most valuable for restoring high-frequency response in compatible Yorkville and related drivers without modifying the horn or wiring, and it performs as expected when the physical fit and impedance match the original unit.

Key Features

• Direct compatibility: Fits a range of Yorkville models and D18C120 style drivers so the diaphragm can be swapped without adapter parts.
• Correct impedance: The 8 ohm rating ensures electrical compatibility with drivers that expect this load, avoiding mismatched frequency response.
• Precise mounting: The center distance of post terminals at approximately 104mm (4.0in) matches the driver layout for clean installation.
• Compact voice coil: The 25.0mm (0.98in) voice coil diameter is sized for typical high-frequency diaphragm dynamics in these driver families.
• Standard flange size: Outer ring diameter around 50mm (1.96in) keeps the mounting footprint small and compatible with original housings.

Who It's For

This replacement is aimed at audio technicians, live sound engineers, and DIY repairers restoring Yorkville 7448, 7461, 7573 and similar drivers where an 8 ohm diaphragm and the listed physical dimensions are required. It is particularly useful when the original diaphragm has failed and the goal is a like-for-like restoration of HF performance.

Users who should look elsewhere include those with drivers that have different terminal spacing, voice coil diameters, or impedance values, or anyone seeking a tuned aftermarket upgrade with measured frequency-response improvements beyond factory spec.

Pros & Cons

Pros

• Direct-fit compatibility with several Yorkville models reduces installation time for repairs.
• 8 ohm impedance matches common high-frequency drivers, avoiding electrical mismatch issues.
• Compact outer ring and measured terminal spacing make alignment in existing housings straightforward.
• Simple, serviceable design suitable for field repair or shop refurbishment.

Cons

• Limited information on acoustic tuning or material specifics means it is a practical replacement rather than a performance upgrade.
• Not suitable if the original driver uses different physical or electrical dimensions.

Frequently Asked Questions

Will this diaphragm fit my 7573 driver?
Yes - it is listed as compatible with the 7573 and uses the same post spacing and impedance for a direct swap when dimensions match.

What impedance is this diaphragm?
The diaphragm is specified as 8 ohm, matching common high-frequency drivers it is intended to replace.

Does it require adapter parts to mount?
In most cases no, since the outer ring diameter and post center spacing are designed to match the original mounting points on compatible drivers.
