1 / 3
A good-value upgrade that noticeably brightens mids and highs, offers improved clarity and perceived volume, and fits low‑profile mounting locations well. Bass is generally tamer than some factory speakers and results depend on vehicle/head unit and minor bracket fitment.

Overview
With its 51 mm (2,0 in.) maximum depth Hertz DCX 170.3 car audio coaxial, 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.
