Features

Mille Legend ML 280.3

  • 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.

Frequently Asked Questions about Mille Legend ML 280.3


How does the geometry of the Tetolon Dome improve the frequency response of the Mille Legend ML 280.3?

The optimized geometry of the Tetolon Dome in the Mille Legend ML 280.3 significantly enhances the frequency response by adjusting the structure of the dome for low distortion in the high-frequency range. By using FEA simulations, the radiation characteristics have been improved to achieve accurate and clean highs, which is particularly important for discerning audiophiles who value high detail fidelity. The dome geometry is designed to optimize a higher frequency bandwidth, enhancing the enjoyment of music listening. These details make the Dome Tweeter a recognized reference.

What role does the acoustic chamber play in the Mille Legend ML 280.3?

The improved acoustic chamber of the Hertz Mille Legend ML 280.3 plays a crucial role by optimizing the response at low frequencies. With an Fs value set at 900 Hz, the performance in the bass range is enhanced, resulting in less distortion from the tweeter even in the transition range. The material density in the chamber ensures controlled vibrational behavior. High-quality absorbing materials effectively prevent unwanted resonances, significantly improving sound quality and enabling clear, uncolored reproduction.

What materials are used for the dome of the Mille Legend ML 280.3 and why?

The Mille Legend ML 280.3 uses a Tetolon fiber for the dome. This fiber is known for its low distortion and fine radiation characteristics, especially in the high-frequency range. Tetolon is specifically optimized for a significant reduction of self-resonances. For enthusiasts seeking the purest sound reproduction, this material offers the ideal balance between stiffness and damping, supporting precise and natural sound dispersion. This material composition makes the ML 280.3 a favorite among high-quality tweeters.

What makes the neodymium magnet in the Mille Legend ML 280.3 so special?

The neodymium magnet in the Mille Legend ML 280.3 is specifically optimized with FEA simulations to ensure maximum control and quick responsiveness to transients. This optimization allows for precise control of the magnetic flux, which ensures high power density with minimal space requirements. The intensive simulation achieves exceptionally good high-frequency extension, making the tweeter particularly suited for high-resolution audio systems. This significantly contributes to the recognized reputation of the ML 280.3 as a reference-class tweeter.

How does the voice coil affect the performance of the Mille Legend ML 280.3?

The heart of the Mille Legend ML 280.3 is the 28 mm voice coil, which plays a crucial role in sound generation. The voice coil is designed for high load capacity and can handle peak values of up to 180 watts, with the 4-ohm impedance providing a balanced resistance. This technical design enables a clean response to electrical signals, while the voice coil remains protected from overheating through heat dissipation via the neodymium magnet motor. For fans of rich music playback, this balance between power and efficiency is essential.

What mechanical properties influence the sound of the Mille Legend ML 280.3?

Mechanically, the structural elements of the Mille Legend ML 280.3 are designed to minimize resonances and positively influence the sound. A CNC-milled frame and a solid aluminum chamber contribute to a mechanically inert structure that effectively dampens unwanted vibrations. This construction reduces distortion and significantly improves sound propagation. Reinforcing materials under the dome tweeter also contribute to optimization by enabling uniform reproduction across a wide frequency spectrum from 1 kHz to 28 kHz.

What electro-acoustic specifications characterize the Mille Legend ML 280.3?

Electro-acoustic, the Mille Legend ML 280.3 is equipped with a re-impedance of 3.3 ohms and an inductance value of 0.013 mH, ensuring very precise and interference-free transmission of electrical signals. The Mms value is 0.4 g, allowing for a sensitively designed diaphragm movement, while the total quality measurement (Qts) is 1.3, perfectly tuned to the expected listening environment. The combined values of the electro-acoustic specifications ensure a sonically consistent reproduction across the entire frequency spectrum.

How does the Mille Legend ML 280.3 ensure extended high-frequency reproduction?

The extended high-frequency reproduction of the Mille Legend ML 280.3 is achieved through the extremely pure copper short-circuit ring, which, together with the aluminum die-cast front plate, improves the radiation behavior. The combination of these materials reduces distortion and enhances acoustic clarity. FEA-optimized structures further contribute to the clean and uncolored reproduction of high frequencies, making even the smallest details audible. This makes the ML 280.3 ideal for discerning music lovers who want to hear every detail of their recordings.

Is the Mille Legend ML 280.3 compatible with my car interior?

The Hertz Mille Legend ML 280.3 Tweeter is designed with a diameter of 35 mm and specific installation dimensions of 53.4 mm (A) x 48 mm (B) x 29 mm (C) x 13.5 mm (D), fitting into many standardized car interiors. Its compact dimensions facilitate integration into existing speaker systems, as long as the structural space in the vehicle is sufficient. It is important to measure the exact space in the car before installation and ensure that the installation location meets the specifications to guarantee optimal performance.

What frequency response characteristics does the Mille Legend ML 280.3 have?

The Mille Legend ML 280.3 from Hertz offers an outstanding frequency range from 1 kHz to an impressive 28 kHz.
