Much time was invested in the research of the perfect material for the C 165 woofer cones: through a long process of customization of the materials SPP-M was selected (Semi Pressed Paper-Mica), which preserves the natural sound of the semi-pressed paper and enhances it with Mica powder improving rigidity. The result is an excellent balance between lightness and damping, essential for a powerful and controlled emission. The oversized ferrite magnet provides excellent control even at higher excursions.

1. 165 mm (6.5 in.) semi-pressed paper cone SPP-M (Semi Pressed PaperMica) enhanced with Mica powder for an excellent balance between lightness and damping.
2. High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
3. 25 mm (1 in.) voice coil featuring an aluminum former to guarantee high excursion and power handling.
4. Compact and transparent three-spoke basket acoustically combined with a rubber magnet cover for total damping of spurious vibrations.
5. Optional elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh.
