HMX 8-LD-TW by Hertz
Hertz HMX 8-LD-TW is an 8-inch (20 cm) coaxial speaker in marine design with integrated RGB LED lighting. The construction features a UV-resistant polypropylene diaphragm with co-molded Santoprene rubber surround, as well as a basket and grille made from high-temperature and UV-resistant polymer. An acoustic system with a front plate and acoustic lens is designed for off-axis operation and high sound pressure levels. The tweeter operates with a 36 mm neodymium magnet and PEI dome, while the woofer has a 32 mm voice coil and flux ferrite magnet; Xmech is ±8.5 mm. The sealed, built-in crossover includes a resettable solid-state tweeter protection circuit, and the terminals are gold-plated and corrosion-resistant. Technical specifications include 100 W RMS, 200 W Peak, 4 Ohm, frequency response 45–25000 Hz, depth 123 mm, and a weight of 1.66 kg per speaker. The design includes an aramid fiber spider with silicone-insulated connection wires and a FEM-optimized drive system in an injection-molded polymer basket.
