2.5" Tweeter Diaphragm 50 Pack

This pack contains fifty 2.5-inch phenolic diaphragm units designed for compression horn drivers. They suit installers and hobbyists who need a quantity of replacement or upgrade parts for car audio and other sound systems. The self-centred and un-centred variants fit different driver configurations.

Sustained acoustic performance

The rigid phenolic construction with a precision voice coil maintains consistent output during extended playback. An aluminium bobbin aids heat dissipation so the diaphragm resists thermal compression when driven continuously at typical power levels.

Thermals and power handling

The aluminium bobbin conducts heat away from the voice coil to keep operating temperatures stable. Phenolic material retains its stiffness under normal thermal cycling, preventing distortion caused by material softening.

Questions about this item

How much heat does the 2.5" phenolic voice coil with aluminium bobbin dissipate during extended use?

The aluminium bobbin is designed for good heat dissipation, helping the rigid assembly maintain high acoustic properties during normal service.

What horn driver units are compatible with the self-centred and un-centred diaphragms in this 50-piece pack?

These diaphragms suit different compression-type horn drivers; the 2.5" voice coil diameter must match the driver you intend to repair or build.

Will the 10-pack DP1 tweeters integrate with an existing crossover network in an older speaker cabinet?

Each 2.5" phenolic diaphragm presents a standard compression-driver interface, so it can work with a crossover designed for that impedance and frequency range.
