The Mille Legend ML 1800.3 from Hertz is a 6.5" woofer with an RMS power handling of 200 W and a peak power of 400 W. The impedance is 4 ohms, while the voice coil has a diameter of 50 mm. The frequency response ranges from 38 Hz to 6 kHz, enabled by a pressed pulp membrane with cotton fibers and a neodymium magnet. Technical parameters such as Xmech ±10 mm and a sound pressure efficiency of 93 dB distinguish it. The aluminum basket has integrated ventilation holes and ensures low distortion at high power.
The Boundary Free Surround technology of the Mille Legend ML 1800.3 ensures a wider emission area of the cone, resulting in a higher sound pressure level. The IIR rubber surround increases efficiency and achieves a broader mid-bass frequency. This construction not only provides improved bass reproduction but also optimizes linearity and dispersion. As a result, the acoustic accuracy and control are significantly enhanced, which is particularly evident in demanding musical passages, without losing performance complexity.
The 50 mm voice coil of the Mille Legend ML 1800.3 is made of CCAW (copper-coated aluminum wire) on a polyamide coil carrier, providing exceptional load capacity. This construction allows for compression-free reproduction even in demanding musical passages. The large-sized voice coil increases control and precision, resulting in improved sound accuracy. The material and size make it particularly resistant to mechanical and thermal stresses. This ensures long-term stability during intensive use.
The Mille Legend ML 1800.3 uses high-quality materials. The neodymium magnet is optimized for maximum dynamics and control, while the CNC-milled plates made from low-carbon material provide extreme magnetic permeability. The speaker features a three-spoke aluminum alloy basket with integrated ventilation holes. The diaphragm is made from a pressed pulp mixture with cotton fibers to provide stiffness at a low weight. Additionally, the surround and the factory-cast aluminum grill are finished with an elegant, diamond-cut finish, adding aesthetic accents.
The exponential V-cone of the Mille Legend ML 1800.3 by Hertz is optimized for maximum linearity and dispersion. Its geometry allows for more precise sound radiation, improving frequency response and sound quality. The combination of this technology with the pressed pulp membrane and cotton fibers enhances the rigidity of the structure and reduces unwanted membrane movements. This improved stability results in a finely tuned sound resonance behavior that exhibits minimal distortion even at high volumes. This technique supports a seamless sound image and increases musical detail fidelity.
The Mille Legend ML 1800.3 speaker has several physical dimensions that are crucial for compatibility with common vehicles. It has an outer diameter of 184 mm, accompanied by an installation depth of 76 mm, while the cutout requires a diameter of 160 mm. These dimensions make it universally compatible with many speaker cutouts in vehicle doors or custom installations. Note that any existing mounting brackets may need to be considered for an optimal fit.
The neodymium magnet in the Mille Legend ML 1800.3 is designed to deliver maximum dynamics and control. Optimized through FEA simulations, it enables maximum magnetic force in compact dimensions, creating an effective magnetic field for the voice coil. This results in high efficiency and low distortion, even under heavy load. The compact design of the neodymium magnet also contributes to reducing the overall weight, which increases mounting flexibility and ensures a dynamic, low-distortion sound, especially at varying volume levels.
The frequency response of the Mille Legend ML 1800.3 ranges from 38 Hz to 6 kHz, thus covering a wide range from bass to mid-high tones. This is achieved through the use of a pressed pulp membrane with cotton fibers, which ensures excellent stiffness and uniform sound dispersion. The exceptional linearity allows for clear and powerful reproduction of lower frequencies, with the neodymium magnet and the special membrane geometry being responsible for this. The sophisticated construction allows for clear sound reproduction with a natural transition between different frequency ranges.
The 4-ohm impedance of the Mille Legend ML 1800.3 ensures efficient integration into most car audio amplifier systems. A lower impedance can allow for higher amplifier currents, which can increase overall system output power by reducing the total load on the amplifier. This adjustment is crucial for optimizing the performance and sound quality of the entire audio system. Impedance plays a key role specifically in the acoustic performance of the speaker, as it governs the interaction between the speaker and the amplifier.
The membrane of the Mille Legend ML 1800.3 is made from a pressed pulp mixture with incorporated cotton fibers, which provides additional stiffness while keeping the weight low. This material combination allows for excellent sound radiation and minimizes unwanted vibrations or break-up at high frequencies. The natural damping of the cotton fibers reduces distortion and ensures fine sound detail fidelity. This combination reproduces the widest frequency range, resulting in more precise sound reproduction, which is particularly crucial for complex musical pieces.
