Picked to replace the standard rear speakers in the R50, R52 and R53.
To meet all installation needs, without giving up on Hertz quality and performance, the Hertz Dieci DCX 690.3 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.
