Hertz DCX 87.3 is a compact two-way coaxial speaker from the Dieci Series, engineered for high-performance sound in installations with limited mounting depth. It combines a water-repellent pressed paper woofer with a neodymium tweeter featuring a PEI dome, delivering controlled output and wide frequency response from a small footprint. The DCX 87.3 is designed for factory replacement and space-constrained applications where standard speaker sizes are not possible. Despite its compact 3.5-inch size, it uses an oversized magnetic group to maintain control and efficiency, making it suitable for OEM upgrade scenarios requiring clarity and reliability.
