Hertz CK 165 component speakers (165 mm).

Hertz CK 165 (CENTO series) 2-WAY component speakers 6.5" (165 mm).

Two-way systems Cento CK 165 features the new C 26 tweeter featuring a 26 mm (1 in.) Tetolon® dome and 20 mm (0.8 in.) voice coil for a detailed and natural reproduction of medium-high frequencies. 
The R&D team worked extensively to optimize the C 26 dispersion characteristics to maximize performance on the listening point, with a natural and progressive roll-off and a natural timbre that favors frequency linearity. 
Much time was invested in the research of the perfect material for the C 165 woofer cones: through a long process of customization of the materials SPP-M was selected (Semi Pressed Paper-Mica). 
The result is an excellent balance between lightness and damping, essential for a powerful and controlled emission. 
The oversized ferrite magnet provides excellent control even at higher excursions. 
The ultra compact CCX 2 crossover featuring tweeter emission level control (0, +3 dB) uses selected components for a full and engaging sound. 
The CG 165 grilles included in the Cento systems brighten up the car interior with their sophisticated design. 
Made of high resistance ABS with metal mesh, they offer a high degree of protection within a compact size, ideal for in-car installation.
