DCX 170.3 Coaxial | 100 W Peak Power | 170 mm | 4 ohm

With its 51 mm (2,0 in.) maximum depth the DCX 170.3, is a flat car audio coaxials optimized for installation in a vehicleâ„¢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.
