Hertz DCX 130.3 (DIECI series) 2-Way Coaxial Speakers 5" (130 mm).

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.
