The HMX 8 LD hi-performance marinet coaxial speakers with RGB LEDs lighting option,  also available in the black option HMX 8-LD-C,  is optimized to perform in infinite baffle, with a solid bass and an outstanding output.  The HMX tweeters feature an acoustic lens optimized for best off-axis dispersion and maximized SPL. The attractive stainless steel tweeter mesh grille provides perfect high-frequency transfer and a rock-solid protection.  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.
