The Hertz DCX 690.3 is a 3-way coaxial speaker from the Dieci series, designed to bring a full and expressive sound to your car's audio system. These 6 x 9 inch elliptical speakers feature a water-repellent pressed paper cone with a protective impregnation, which helps maintain performance even in challenging climates. To ensure a clean output across the frequency range from 45 Hz to 21 kHz, they incorporate a 60 mm paper tweeter and a 15 mm heat-resistant polyetherimide super tweeter with a diffuser disk. Built for durability and efficiency, the speakers utilize an elastic thermoplastic polyurethane surround that is both wear-resistant and resonance-free. Inside, a high-density flux ferrite magnet is protected by a butyl rubber cover, while the DIN size basket is finished with abrasion-proof dust paint. With a sensitivity of 93 dB, you can achieve loud, clear volume even when using low-power head units. These units handle 90 W RMS and up to 180 W peak power, making them a reliable choice for drivers who want an upgraded listening experience without needing an expensive external amplifier.
