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 RD 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.
