With its 51 mm (2,0 in.) maximum depth Hertz DCX 170.3 is a “flat” model optimized for installation in a vehicle’s door and/or other reduced spaces, without giving up on acoustic reproduction quality. A Neodymium magnet, PEI dome tweeter, built-in crossover, TPU (Thermoplastic polyurethane) surround, a copper voice coil wound on a Conex former and painstaking care in its build ensures performance surpassing other components within the same category.
