HERTZ ML 1650.3 Woofer – SET
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 as 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.
