HERTZ Marine Speakers Coaxial 8.8″ | RGB LED | 200 W | 4 Ohm
HMX 8 LD-TW hi-performance marine coaxial speakers with RGB LEDs lighting option, feature a tone-on-tone front mesh matching the grille colour. The tweeter acoustic lens optimizes off-axis dispersion and maximized SPL.
The RGB LED lighting circuit is integrated below the tweeter, protected by a Polypropylene transparent cover acting as light diffusion. The UV-resistant polypropylene cone co-molded with Santoprene rubber surround together with the basket and grille injected with a Hi-temperature and UV resistant polymer neutralize water, dust and mud. The aramid fiber spider with silicone-insulated lead wires ensures durability and constant performance over time. The high-excursion mobile equipment is driven by a massive magnetic group, to deliver high undistorted sound pressure.
