Hertz Mille Pro ML 280.3 LEGEND 1.38″ Tweeters

Reference-Grade High-Frequency Performance

The Hertz Mille Pro ML 280.3 LEGEND tweeters are the result of years of refinement in high-end car audio design. Recognized as a benchmark for clarity and precision since their introduction, these tweeters have been further enhanced through meticulous engineering and advanced FEA (Finite Element Analysis) simulations. The redesigned Tetolon dome geometry minimizes distortion, while the optimized faceplate improves frequency response, ensuring incredibly smooth and detailed highs.

Enhanced Acoustic Design for Lower Distortion

To push performance even further, the rear acoustic chamber has been completely re-engineered with a 50% increase in internal volume. Combined with premium damping materials, this design lowers the resonance frequency to just 900Hz, enabling a more natural transition to the midrange and extending the frequency response.

Precision Components for Unmatched Clarity

The 28mm voice coil and powerful neodymium magnet deliver exceptional efficiency and power handling. Every material choice, from the Tetolon fiber dome to the carefully selected damping components, is optimized to reproduce every high-frequency detail with lifelike accuracy.

Key Features

• 1.38″ (35mm) Tetolon dome tweeter with optimized geometry for low distortion

• 180W Peak / 4Ω impedance for high dynamic range and easy system integration

• Rear acoustic chamber with 50% greater volume for lower resonance and extended response

• Neodymium magnet for compact size and high sensitivity

• Optimized faceplate geometry for improved off-axis performance

• Wide frequency response from 1kHz to 28kHz

• High sensitivity of 92dB for detailed highs even at lower volumes
