Cento Pro CPX 690 by Hertz
Hertz Cento Pro CPX 690 is a 6 x 9 inch speaker set in a 3-way design. It combines Neodymium tweeter and Neodymium super tweeter with Tetolon domes, as well as a water-repellent pressed paper membrane and a wide rubber surround. The woofer uses a ferrite magnet and a 30 mm voice coil; the tweeter features a 28 mm voice coil and a 32 mm tweeter membrane. The metal basket relies on a radial venting system; the front plate geometry is FEM-optimized. The load capacity is 120 W RMS and 360 W peak at 4 Ohm impedance, with a frequency response ranging from 35 to 24,000 Hz. An ABS plastic frame with a metal surface and protective metal grille is integrated. Xmech is 7.5 mm, and the weight is 1.63 kg.
