HMX 6.5-LD-TW by Hertz
HMX 6.5-LD-TW is a 6.5-inch Marine Coaxial Speaker from Hertz with an integrated RGB LED lighting option and acoustically optimized design for off-axis operation. The power handling is 75 W RMS and 150 W Peak at 4 Ohm impedance, with a frequency response ranging from 50 to 25,000 Hz. The diaphragm is made of polypropylene with UV inhibitors, combined with co-molded Santoprene surround and aramid fiber spider with silicone-insulated connection wires. The woofer uses a 25 mm voice coil and a high-density ferrite magnet, while the tweeter features a 36 mm PEI dome, 20 mm voice coil, and neodymium magnet. A sealed, built-in Crossover with resettable solid-state tweeter protection circuit is integrated. The sound-transparent tone-on-tone tweeter grille is made of stainless steel, and the massive magnetic group is encapsulated in an injection-molded marine-grade polymer basket. The system is designed and tested for UV, salt mist, vibrations, splash water, temperature shock, and dust. The depth is 95.6 mm, Xmech is ±6.65 mm, and the weight per speaker is 1 kg.
