Product Details

The Hertz Cento Pro CPK 165 PRO car audio system includes the CP 165 woofer and the CP 25 tweeter with Tetolon dome and 25 mm voice coil, features ensuring a very wide and linear frequency response. The CP 25 Tweeter employs the “Center Tuning Duct” technology: the tunnel at the center of the powerful Neodymium magnetic circuit, ensures low-temperature air exchange between the dome and the rear loading chamber, perfectly tuning the acoustics.

The resulting very low resonance frequency is also functional for the woofer crossover point, elevating the sound stage. The sophisticated design of the mobile group and suspensions of the CP 165 woofer, featuring a 60Hz calibrated resonance frequency, ensures a medium-low power with excellent punch, making listening to rich low frequency genres a unique experience. The basket is consistent with the family-feeling of the Mille line with the addition of damping and protective rubber. The cone material is inherited from the Mille Pro, as well as the suspension butyl rubber and the Tetolon fiber of the tweeter dome.

These materials have excellent damping and lightness characteristics, producing a balanced sound without resonance peaks. The gift box includes the woofers grilles made of a combination of metallic mesh and high resistance ABS plastic frame. The combination of these two elements allows the user to customize the installation with a sophisticated and elegant design.


CP 25 Tweeter:

  • Soft 29 mm Tetolon fiber dome, for a natural as well as detailed reproduction of music nuances.
  • “Center Tuning Duct” geometry, for lower resonance frequency and reduced harmonic distortion.
  • Neodymium magnet with high-density magnetic flux, optimized for maximum control during high-energy dynamic transients in the mid-high frequency range.
  • 25 mm mobile coil cooled with ferrofluid.
  • Rear chamber filled with damping material selected and sized for low resonance, ensuring a natural mid range allowing a low cut-off frequency crossover point.
  • Faceplate geometry optimized with FEM (Finite Element Modeling) technology for a linear frequency response in off-axis installations.
  • Wide range of accessories provided, for easy integration.

CP 165 Woofer:

  • Pressed paper cone with FEM-optimized geometry combining rigidity and lightness for color-free sound.
  • High density ferrite magnet in combination with low carbon polar plates for a reduced distortion at high power levels.
  • 25 mm diameter pure copper coil to guarantee high excursions.
  • 3-spoke, compact and transparent basket acoustically combined with a rubber magnet cover for an overall damping of spurious vibrations.
  • Stylish grille with high resistance ABS plastic frame with metal finish combined with a protective metallic mesh.

CPCX 2 Crossover:

  • Tweeter level adjustable via a three-position switch (-2, 0, +2 dB) for optimized and customizable timbre balance.
  • 160V extremely high quality bi-metallized polyester film capacitors with ultra-low DF and pure copper low resistance inductances, for maximum sound transparency and high clear frequencies.
  • Compact design with metallic finish for ease of installation, featuring air vents for efficient heat dissipation.
