Hertz Cento CK 165 F

The CENTO CK 165 F is a 6.5" front system set from Hertz, which is one of the pioneers on the market due to its innovative features. The system is characterized by its new C 26 tweeter with a 26 mm Tetolon membrane and a 20 mm voice coil, which ensures a detailed and natural reproduction of the high-mid frequencies. Its balanced frequency response offers you maximum performance, no matter where you are. After intensive research, the CK 165 woofer was developed  F, a perfectly matched membrane material was chosen that impresses with its excellent balance between lightness and damping. The ultra-compact crossovers and the included speaker grille round off this offer and make the CENTO CK 165 F an excellent choice for any car hi-fi system.
