Hertz Cento Pro CPK 165 - 16.5 cm 2-Way Front System for Clear Treble and Powerful Bass
The Hertz Cento Pro CPK 165 is a 2-way component system that precisely and balancedly reproduces your vehicle's sound. It combines the CP 165 woofer with the CP 25 tweeter for a wide, linear frequency response. The Center Tuning Duct technology optimizes air exchange in the chassis and helps control resonances. Light, well-damped materials and a low resonance frequency of the woofer ensure clean bass and detailed mids. With the passive 2-way crossover, you safely separate at 2.8 kHz â ideal for a cohesive soundstage and clear treble. Available at Carhifi.shop.

Installation & Compatibility
The CPK 165 fits into the 165 mm class and operates at 4 Ohm â ideal for many factory and aftermarket radios as well as powerful amplifiers. The external, passive 2-way crossover facilitates clean separation between the CP 165 and CP 25. Position the 29 mm tweeter as close to ear level as possible (e.g., A-pillar or mirror triangle) to improve the soundstage. For dynamic reserves, an amplifier power of around 100 W RMS per channel is recommended.
