Hertz CK 165 L (CENTO series) 2-Way Component Speakers 6.5" (165 mm).

The Cento line expands with the C165 L woofer, featuring the use of non-pressed paper for the cone membrane, a choice that gives this component a natural sound, with solid and controlled low frequencies. 
The enhancement of the magnetic group together with the specific wide stroke voice coil allow the excursion of the woofer to be maximized maintaining utmost control even in the most demanding musical passages. 
The CK 165 L system consists of the C 165 L woofer, the C26 tweeter and the crossovers dedicated to the CCX 2W woofer and CCX 2T tweeter, made with selected components.
The ultra-compact dimensions of the crossovers and the wire connections provide the specialist with a broader freedom during the installation. 
The tweeter filter is 12 dB/oct. with two levels of attenuation while for the woofer, thanks to its regular frequency roll-off, a 6 dB/oct. made with a pure copper high diameter coil is used to the advantage of reduced electrical losses and therefore of low frequencies efficiency. 
The engaging low frequencies and impressive power handling make the CK 165 L the perfect system for fans looking for strong emotions in the car cabin.
