Hertz Mille Legend Series ML-18003 7" (180mm) Woofers with Neodymium Magnets and Grilles (Pair)

ML 1800.3 Legend car audio woofers has been thought and designed for the enthusiasts attending contests who need a component merging the timbre accuracy of ML 1650.3 Legend to a wider extension to the low frequencies thanks to the large emission surface, higher power handling and control which only a 50 mm voice coil can ensure. 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. Like in the suspensions of competition cars, the surround must stand the most extreme working conditions to ensure maximum stability and symmetry at high excursions, and so to achieve impact and extension to the low frequency range. For this reason, the electro-acoustic designers developed a new surround-basket gluing system called “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.
