Woofer Auto Hertz Mille Legend ML 1800.3

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.
