The Hertz CPK 690 Cento PRO speaker system is designed to deliver superior audio performance in configurations with 6×9-inch elliptical woofers, an ideal solution for the most common OEM positionings in North American vehicles, such as Toyota and Ford groups. The woofer uses a pressed paper cone, a material chosen to ensure linear and controlled sound output, even at high powers. The optimized geometry using FEM (Finite Element Modeling) technology ensures rigidity and lightness, contributing to an extended frequency response of up to 35 Hz. The 30mm dual layer voice coil is designed to offer a wide range and excellent power management, while the high-density ferrite magnet minimizes distortion even at high volume levels. The CP 25 tweeter with 29 mm Tetolon fibre dome and “Center Tuning Duct” geometry ensures a natural reproduction of high frequencies, characterized by extraordinary level of detail and low harmonic distortion. Optimized neodymium magnet allows dynamic transients to be handled with extreme precision. Damping filled rear chamber contributes to a natural mid-range and reduced crossover frequency. The CPCX 690 crossover offers customizable adjustments for the tweeter, with a three-position switch (-2.0, +2 dB) that allows you to adjust the tonal balance to your personal preferences. Made with high quality components, such as low loss polyester capacitors and pure copper inductances, the crossover ensures unparalleled sound transparency. Compact design with air vents makes installation easier and improves heat dissipation. Combining premium materials, advanced design and uncompromising attention to detail, the Hertz CPK 690 is the ideal choice for those who want an immersive and faithful audio experience that enhances every musical detail.
