The Hertz DCX 87.3 is a 2-way coaxial speaker from the Dieci series, designed to bring clear audio to smaller mounting locations in your vehicle. These speakers combine an 87 mm woofer with a 15 mm tweeter, delivering a frequency response from 130 Hz up to 21 kHz. With a continuous power handling of 30 W and a peak of 60 W, they provide a reliable performance that is efficient thanks to a sensitivity of 92 dB. Built for durability, the woofer features a water-repellent pressed paper cone with a protective impregnation, while the tweeter uses heat-resistant polyetherimide. The internal construction includes a high-density flux ferrite magnet and a pure copper voice coil on a conex former, ensuring stable control and longevity. To keep the components secure and rust-free, the DIN size basket is finished with abrasion-proof dust paint and utilizes epoxy glue for the motor system coupling. Measuring 87 mm in diameter and 45 mm in depth, these speakers fit easily into tight spaces using their universal protruding mounting flange ears. The use of silver-plated lead wires and tin-plated high-current terminals ensures a clean electrical signal, making them a practical choice for drivers who want to replace factory speakers with a more capable audio solution without needing extensive modifications.
