CPK 690

The latest addition to the Cento PRO line is the CPK 690 system equipped with an elliptical woofer to avail of the 6 x 9 door placements, which are particularly common in the North American market, such as for the models of Toyota and FORD groups. Like the other speakers of the Cento PRO line, the woofer cone is made of pressed paper, the most suitable material to obtain a linear and controlled emission even when the woofer is driven with very high power. All electroacoustic parameters have been optimized to obtain maximum performance with door installations; we therefore find a magnetic group and voice coil improved for an excellent power handling and a lower resonance frequency. The large emission area of the CP 690 increases the woofer efficiency and extends the response down to 35 Hz.  The crossover made with selected components, features a low-pass filter on the woofer with a 6 dB/oct. slope and 12 dB/oct. on the tweeter with three levels of attenuation. CPK 690 is dedicated to the young enthusiast who wants a front row seat at their favorite concert while sitting comfortably behind the steering wheel.

Features

1. Pressed paper cone with FEM-optimized geometry combining rigidity and lightness for color-free sound.
2. Wide rubber suspension designed for a long excursion and excellent sound damping.
3. High density ferrite magnet in combination with low carbon polar plates for a reduced distortion at high power levels.
4. Metal finished basket combined with an anti-vibration rubber magnet cover for an overall damping of spurious vibrations.
5. Soft Tetolon fiber dome Neodimium tweeter featuring a 28 mm mobile voice coil, for a distortion-free reproduction of mid-high frequencies.
6. Tetolon fiber Neodimium Supertweeter featuring a 20 mm mobile voice coil, to compensate for the natural fall of high frequency response in horizontal installations.
7. Faceplate geometry optimized with FEM (Finite Element Modeling) technology for a linear frequency response in off-axis installations..
8. Stylish grille with high resistance ABS plastic frame with metal finish combined with a protective metallic mesh.
