1. 6x9 in. semi-pressed paper elliptical cone SPP-M (Semi Pressed
Paper-Mica) enhanced with Mica powder for an excellent balance between
lightness and damping.
2. Wide rubber suspension engineered for a long excursion and excellent sound
damping.
3. High-density flux ferrite magnet combined with low-carbon polar plates for
reduced distortion at high power levels.
4. Basket with metallic finish acoustically combined with a rubber magnet
cover for total damping of spurious vibrations.
5. 40 mm (1.58 in.) dome tweeter for efficient distortion-free mid-high
frequency reproduction.
6. 20 mm (0.8 in.) dome supertweeter to maximize the level of very high
frequencies in horizontal installations.
7. Tweeter faceplate geometry optimized with FEM simulations (Finite
Element Modeling), to provide an extremely linear frequency response
in off-axis installations.
8. Provided elegant grille made with high-resistance ABS plastic structure with
a metallic finish combined with a protective metal mesh.
