The Hertz DCX 460.3 is a 2-way coaxial loudspeaker from the Dieci series, designed to fit 4 x 6 inch mounting spaces. These speakers handle 40 W of continuous power and can reach peaks of 80 W, delivering a frequency range from 65 Hz up to 21 kHz. To ensure clear sound, they feature a 15 mm heat-resistant PEI dome tweeter with a neodymium magnet and a woofer made from water-repellent pressed paper. This cellulose cone is paired with a wear-resistant TPU surround to keep the audio resonance-free. Built for durability and ease of installation, the speakers have a shallow HF center pillar and open mounting holes on protruding lugs. The internal components include a pure copper voice coil wound on a conex former and a high-density ferrite magnet. To protect against the environment, the basket is finished with abrasion-proof dust paint, while silver-plated lead wires and tin-plated terminals ensure a reliable electrical connection. With a depth of 53 mm and a weight of 0.58 kg, these units provide a balanced upgrade for drivers looking for efficient sound reproduction without needing extensive modifications to their car's interior.
