CG 690 grile Provided

Composed by a high-resistance ABS plastic support and metal mesh, to ensure a high degree of protection with a Hi-tech design.

  • 1. 6×9 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.
