Hertz CX690 Cento Series 6×9″ 3-Way Coaxial Speaker Set with Grilles

Description

Highlights

The three-way elliptical coax CX 690 featuring a 6×9 inch cone was designed to achieve maximum performance in horizontal installations and offering, even in this difficult condition, an exceptional tone balance and power handling.

Features

• 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.
• Wide rubber suspension engineered for a long excursion and excellent sound damping.
• High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
• Basket with metallic finish acoustically combined with a rubber magnet cover for total damping of spurious vibrations.
• 40 mm (1.58 in.) dome tweeter for efficient distortion-free mid-high frequency reproduction.
• 20 mm (0.8 in.) dome super tweeter to maximize the level of very high frequencies in horizontal installations.
• Tweeter faceplate geometry optimized with FEM simulations (Finite Element Modeling), to provide an extremely linear frequency response in off-axis installations.
• Provided elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh.
