Component: 2-Way System Crossover: 2-Way Passive Crossover Tweeter Magnet: Neodymium Woofer Cone: Pressed Paper Cone Tweeter Dome: Tetolon 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. Features - Soft Tetolon fiber 29 mm (1.14 in.) dome and 25 mm (1 in.) voice coil cooled with ferrofluid, for a natural and yet detailed reproduction of musical nuances. “Center Tuning Duct” geometry, for a lower resonance frequency and reduced harmonic distortion Pressed-paper cone with FEM-optimized geometry, it combines rigidity and lightness for a color-free sound. 30 mm (1.2 in.) double layer voice coil sized to maximize fhigh excursion and power handling. Tweeter level adjustable via a three-position switch (-2, 0, +2 dB) for an optimal tonal balance that can be customized by the user Specifications - Power Handling - Peak W: 360 Power Handling - Continuous W: 120 Impedance Ω: 4 Frequency response Hz: 35 ÷ 22,5k Sensitivity dB SPL: 92 Voice coil Ø mm (in.): 30,5 (1.2) Woofer size mm (in.): 6 x 9 Tweeter size mm (in.): 29 (1.14)
