Voice coil diaphragm for tweeter repair

This 37.8 mm voice coil diaphragm is designed for professional tweeter speakers and DIY speaker projects. It serves as a replacement part for audio enthusiasts restoring or building high-frequency drivers. Buyers who need a complete driver assembly or a different coil diameter should look elsewhere.

37.8 mm inner diameter

The single specification that determines compatibility is the 37.8 mm inner diameter of the coil. The winding uses copper-clad aluminium flat wire formed into a dome shape. Verify this measurement against your existing tweeter before ordering.

Lightweight film construction for sustained

The professional film diaphragm is built for continuous treble reproduction without the compression that can occur in heavier assemblies. Its lightweight dome maintains consistent response during extended listening sessions. The component arrives without retail packaging.

Questions about this item

What difference does a 37.8 mm voice-coil diameter make in a tweeter?

The 37.8 mm inner diameter determines the moving-mass and sensitivity of the diaphragm, so it directly affects how efficiently the tweeter converts amplifier power into high-frequency output.

How does the copper-clad aluminium winding and flat-wire construction affect the driver?

Copper-clad aluminium keeps the coil light for fast transient response, while the flat-wire geometry packs more turns into the 37.8 mm former, raising the motor force without adding bulk.

What mounting provisions does the diaphragm include for DIY installation?

The dome-shaped membrane arrives as a single piece without a frame or adhesive, so the builder must supply a suitable former, centring spider and termination method to complete the tweeter assembly.
