Woofer Auto Hertz ML 1650.3

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.
