Hertz CK165 6.5″ 2-Way Speaker System

SKU: CK165 Category:


Cento Series 6-1/2″ Component Speaker System

Cento CK165 two-way speaker system includes the new C26 tweeter featuring a 26mm (1-inch) Tetolon dome and 20mm (0.8-inch) voice coil for a detailed and natural reproduction of medium-high frequencies. The R&D team worked extensively to optimise the C26 dispersion characteristics to maximise performance on the listening point, with a natural and progressive roll-off and a natural timbre that favours frequency linearity.

Much time was invested in the research of the perfect material for the C165 woofer cones as well: through a long process of customization of the materials SPP-M was selected (Semi Pressed Paper-Mica), which preserves the natural sound of the semi-pressed paper and enhances it with Mica powder improving rigidity.


  • C26 Tweeter:
    • Soft Tetolon fiber 26mm (1-inch) dome and 20mm (0.8-inch) voice coil, for a natural and yet detailed reproduction of musical nuances
    • Neodymium magnet with high-density magnetic flux, optimized for maximum control during high-energy dynamic transients in the mid-high frequency range
    • Faceplate geometry optimised with FEM (Finite Element Modeling) technique for a linear frequency response in off-axis installations
    • Wide range of accessories, for easy integration in OEM placements
  • C165 Woofer:
    • 165mm (6.5-inch) semi-pressed paper cone SPP-M (Semi Pressed PaperMica) enhanced with Mica powder for an excellent balance between lightness and damping
    • High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels
    • 25mm (1-inch) voice coil featuring an aluminium former to guarantee high excursion and power handling
    • Compact and transparent three-spoke basket acoustically combined with a rubber magnet cover for total damping of spurious vibrations
    • Provided elegant grille made with high-resistance ABS plastic structure with a metallic finish combined with a protective metal mesh
  • CCX2 Crossover:
    • Tweeter level adjustment through a three-position switch (0, +3 dB) for an optimal tone balance that can be customised by the user
    • Low-loss factor capacitors and low resistance inductances made with pure copper, for maximum sound transparency and clear high frequencies
    • Compact design with metallic finish for an easy installation, with air vents for efficient heat dissipation
