Hertz HMX 8-S-LD-SW 8" White Hi-End Marine RGB LED Coaxial Speakers (Pair)

The HMX 8 S LD hi-performance powersport coaxial speakers with RGB LEDs lighting option 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.

Key Features

  • RGB Multicolor
    Built-in RGB led lighting creates a sophisticated atmosphere, adding tons of class to your vessel.
  • IP 65 Certification
  • Water Jet Tested
    The protection grade IP65 for speakers define all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
  • UV Resistant
    According to the severe ASTM-D4329 standards for UV resistance, all the materials used for Hertz Marine products are designed to face long time exposition to UV radiations while cruising on the open sea.
  • Salt Fog Tested
    To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.


  • Integrated RGB LED lighting to enhance your experience in combination with the HM RGB 1 BK accessory.
