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.
