Hertz Mille Legend Series ML 280.3 1.38" (28mm) Tweeters with Neodymium Magnet

Hertz ML 280.3 LEGEND is a 35mm (1.38") tweeter pair from the Mille Legend Series, built for high-end car audio systems that need high-frequency detail with controlled dispersion.

The ML 280.3 LEGEND uses a Tetolon fiber dome and a neodymium motor, with a rear acoustic chamber designed for a 900 Hz resonance frequency (Fs) to support lower crossover points when used with proper high-pass filtering.

Key Performance Features

• 35mm (1.38") Tetolon fiber dome tweeter
• Neodymium magnet motor optimized via FEA simulations
• Die-cast aluminum face plate with FEA-optimized geometry for frequency response and dispersion
• Pure copper short-circuit ring to support very high-frequency extension
• CNC-machined aluminum frame structure and rear load chamber for mechanically inert behavior
• Rear chamber design targeted for 900 Hz Fs to extend low-frequency response and reduce distortion near the crossover region
• High-density damping under the dome with low-density absorbing material in the rear chamber

Power Handling

• Peak Power Handling: 180W (Hi-Pass filtered @ 1.8kHz, 12dB/oct)

Installation Use Cases

• High-end front stage builds using passive or active crossovers
• Systems requiring a larger-format tweeter for wider high-frequency headroom
• Mille Legend speaker systems and brand-matched Hertz builds
