During these past few years the Mille line car audio woofers have been the choice of many enthusiasts looking for extreme performance; with ML 1650.3 Legend the Hertz designers increased again the limits of achievable performance for components designed for door installation.

• Neodymium magnet optimized with FEA simulations for real dynamics and utmost control.
• Very low carbon content CNC machined plates, for maximum magnetic permeability and low distortion at high power levels.
• Aluminium covered pole for a linear impedance modulation and low distortion.
• 36 mm CCAW double layer voice coil wound on a Polyamide former for exceptional power handling and compression-free re production even in the most demanding musical passages.
• Exponential V-cone® with optimized geometry for utmost linearity and dispersion at mid frequency range.
• “Boundary Free” IIR rubber surround, for better efficiency and wider mid-bass frequency.
• Pressed-pulp cone with cotton fibres, combining stiffness and lightweight, to achieve wide frequency response and limited break-ups at high frequency.
• Three-spoke, very acoustically transparent anti-resonant aluminium alloy basket featuring built-in venting holes.
• CNC machined elegant diamond-cut basket edge featuring the Hertz logo.
• Die-cast aluminium factory provided grille featuring diamond-cut aluminium Hertz logo.

To get to these results, the R&D staff performed extensive in-car voicing sessions, after building several prototypes with the FEA simulation method and testing them with a wide array of measurements carried out with the Klippel® suite. To ensure extraordinary power handling and very high thermal stability even with tracks especially rich of bass frequencies, ML 1650.3 Legend features a 36 mm mobile voice coil.

This size ensures the best compromise between power handling and high frequency response. The cone geometry has been subject of in-depth studies with FEA simulations and measurements performed with the Klippel Scan Vibrometer; all that led to the optimization of the V-cone® profile. In the subwoofers and in the woofers, to reproduce the lowest frequency spectrum, the cone needs to move a remarkable amount of air, so it is forced to make long excursions moving like a piston does.

The V-cone® profile prevents the cone from deforming during its course, ensuring that the “piston” works in a correct position, maximizing the production of acoustic pressure.
