Hertz Cento CK 165 L - 16.5 cm 2-Way Front System with Tetolon Tweeter
The Hertz Cento CK 165 L is a 6.5-inch component system for the front of the vehicle, designed for clear highs, clean mids, and stable dynamics. At its heart is the C 26 tweeter with a 26-mm Tetolon dome and a 20-mm voice coil. It plays with control and naturalness, even in difficult installation positions. The 165-mm mid-woofer was tuned for a balanced ratio of lightness and damping to deliver precise impulses and good low-frequency reproduction. Ultra-compact, separate crossovers and a suitable speaker grille simplify installation. Available at Carhifi.shop.

Installation & Compatibility
With its 165-mm format, the Cento CK 165 L is ideal as a front system in many vehicles. The separate crossovers simplify placement, and the three-step adjustable tweeter level helps to adapt the reproduction to the seating position and vehicle acoustics. Thanks to optimized dispersion, the system also functions reliably with sideways or angled tweeter positions.
