Compatible with Mille Legend ML 280.3
Mille Legend ML 280.3 by Hertz
The Mille Legend ML 280.3 is a dome tweeter from Hertz. This tweeter is not just an evolution; it has already become a recognized reference since its market launch. The ML 280.3 Legend was born from extensive research and development, with a focus specifically on optimizing the Tetolon dome geometry. Noteworthy is the dazzling geometry, which was further developed to improve frequency response and reduce distortion. Additionally, the device benefits from an improved rear acoustic chamber. Ultimately, this results in a significant improvement in response behavior at low frequencies.

Features

- Neodymium magnet optimized with FEA simulations of the magnetic flux to ensure maximum control and fast transient response.
- Extremely pure copper short-circuit ring for excellent high-frequency extension.
- Aluminum die-cast front plate with a profile optimized by FEA simulations to improve frequency response and radiation behavior.
- Tetolon fiber dome optimized with FEA simulations for lower distortion and improved radiation behavior in the high-frequency range.
- The frame structure and rear loading chamber are both made from a CNC-machined solid aluminum block to ensure mechanically inert behavior against resonances.
- The rear chamber is designed for an Fs value of only 900 Hz: The low Fs value ensures wide extension in the low-frequency range and low distortion even in the crossover region, allowing for a lower cutoff frequency.
- High-density damping material under the dome and low-density absorbing material in the rear chamber ensure smooth sound radiation and high damping in the bass range.
