The Hertzaudio Cento Pro CPK 165 PRO car audio system includes the CP 165woofer 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 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.
