5 Core
A 50-pack of 2-inch phenolic voice coil diaphragms with 51mm Kapton formers and 16-ohm impedance for compression driver repair
The 5 Core DP1 pack supplies fifty 2‑inch phenolic voice‑coil diaphragms built for car‑audio compression drivers. Installers and system owners can refresh or upgrade high‑frequency output across multiple vehicles or speaker cabinets with a single purchase.
Each diaphragm presents a 16‑ohm load, the key specification that determines whether it will work with a given compression driver. Verify the driver’s rated impedance before buying; a mismatch will cause incorrect frequency response or amplifier instability.
The titanium membrane dissipates heat efficiently during normal high‑pitch operation, keeping distortion low and extending service life. No active cooling is required, and the phenolic former remains stable at typical automotive audio power levels.

The 16 ohm rating matches most compression drivers, so your amplifier sees a standard load and the diaphragms draw the current they were designed for.
The phenolic coil on a Kapton former handles heat efficiently, keeping distortion low and preserving the bright, clear high-frequency output.
Each diaphragm measures 51 mm in diameter, matching standard 2 inch compression driver throats for a direct bolt-in replacement.
