Hertz Cento Pro CPX 165

If you value quality and precision, then the CENTO PRO CPX 165 from Hertz could be just the thing for you. It is a 6.5" (16.5cm) coax that offers exceptional sound with a wide frequency response. With a Tetolon tweeter and a neodymium magnet, it is equipped for detailed, airy sound with excellent off-axis properties. Efficient ventilation technology and high-quality materials such as pressed paper for the membrane and butyl for the surround ensure a low resonance frequency and an impressive punch. These and other features make the CENTO PRO CPX 165 a product that impresses both in terms of design and performance.
