Hertz ML 1650.3 Mille Series 6.5" Midbass (Pair)
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. 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.

Key Features:
- V-CONE®
The exponential profile gets very close to the perfect one, providing exceptional dispersion. - Boundary Free Surround
This technology provides the ability to achieve wider emission surface of the cone compared to speakers with same diameter; that way, the cone manages to move a bigger mass of air, so it produces more acoustic pressure.
This special surround is built from highly pure IIR butyl rubber, ensuring extraordinary thermal and mechanical linearity.
Features:
- 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
