A highly capable component speaker set. The Cento CPK 165 Pro woofer features a pressed paper cone. Finite Element Modelled geometry optimises rigidity. A 29mm tweeter features a damping chamber to the rear with a tunnel to aid with cooling at high levels. The chamber ensures a low resonant frequency.
A 2-way passive crossover is provided with - 2dB, 0dB, +2dB switch to satisfy genre and taste preferences.
A three-spoke resonance-free basket with rubber magnet cover reduces interference from spurious vibrations. A rigid ABS grille is provided.

The Hertz audio 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 employs the Center Tuning Duct technology: the tunnel at the centre 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 soundstage. 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 an 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 fibre 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.
The CPX 165 coaxial provides the thrill of listening to the Hertz sound even when the vehicle does not allow the installation of a two-way kit. The Tetolon dome tweeter and Neodymium magnet is provided with off-axis dispersion features and exceptional frequency extension for a detailed, airy sound. Radial Venting System technology ensures unparalleled cooling of the coil thanks to the eight holes at the base of the engine that allow air exchange with the tweeter support.
This acts as a rear camera, sized for low Fs, to ensure a natural midrange and allow a low-frequency crossover point with the woofer. The pressed-paper cone and the butyl rubber suspension offer an extended low-frequency response and an impressive punch. The Mille-inspired design basket features a dampened and protective rubber-coated magnet.
