To meet all installation needs, without giving up on Hertz quality and performance, the Dieci coaxes were designed with maniacal care to provide a linear frequency response and ensure high reliability. A Neodymium magnet, PEI dome tweeter, built-in crossover, TPU (Thermoplastic polyurethane) surround and a pressed-paper cone provide the optimum ratio between installation friendliness and sound with dynamic and emotional impact. The new Hertz Dieci DCX 160.3 6” coaxial includes an adaptor ring designed for installation in GM and Honda models with 6” OEM speakers.
