Hertz Cento CX 690 - 6x9" Coaxsystem

CX 690

Coaxial

The oval 3-way coaxial speaker CX 690 has a low midrange diaphragm in 6 "by 9" and was designed for maximum performance in a horizontal mounting position.
He offers, even under the worst conditions, a balanced tonal balance and a very good efficiency.

SPP-M technology
SPP-M (Semi Pressed Paper-Mica) Membrane improves with Mica Powder for an excellent balance between lightness and damping.

1. 6 "x 9" oval, single pressed SPP-M membrane (Pressed Paper Mica) expanded with Mica powder for an excellent balance of weight and cushioning.
2. Wide rubber bead designed for high stroke and excellent damping.
3. High density ferrite magnet combined with low carbon pole plates for reduced distortion.
4. Basket with a metallic finish which acoustically with a rubber magnetic protection ensures that vibrations of any kind are suppressed.
5. 40mm tweeter for efficient and distortion-free reproduction of high and mid frequencies.
6. 20mm Super Tweeter for maximizing the level of very high frequencies in the horizontal mounting position.
7. The design and geometry of the tweeter faceplate has been optimized with FEM (Finite Element Modeling) simulations for a linear frequency response, even in off-axis installations.
8. Elegant, high loadable ABS ABS plastic speaker grille with metallic finishing and a metal grille.
