The HMX 8.8 S-LD-G.2 is designed for those who demand maximum output, bold styling, and high-impact performance in marine audio systems. This version features the Gray sport grille, delivering a strong, technical aesthetic that perfectly matches performance boats and contemporary deck designs. The SPORT.2 evolution introduces a redesigned central element with parametric mesh grille, combining aggressive styling with enhanced acoustic transparency. At the core of the upgrade is the completely re-engineered crossover, developed to provide a more exciting, dynamic, and engaging sound experience, with improved clarity and output in open-air environments. The powerful 8.8” woofer, equipped with a 32 mm (1.26”) voice coil, ensures deeper bass and higher acoustic output, making it ideal for installations where performance and SPL are key. Built with marine-grade materials – including UV- and salt-resistant ASA grille, polypropylene cone, and Santoprene™ surround – the HMX SPORT.2 guarantees long-lasting durability and reliability even in extreme conditions. The integrated RGB LED lighting allows full customization of the onboard atmosphere, enhancing both performance and visual impact.

Oversized 8.8” long-throw woofer with 32 mm (1.26”) voice coil, specifically tuned for infinite baffle applications to deliver deeper, more powerful, and controlled low-frequency performance
Marine-grade construction, featuring UV- and salt-resistant materials for maximum durability over time
Gold-plated corrosion-resistant terminals, ensuring stable and long-lasting electrical connections
Integrated RGB LED lighting, for full customization of the onboard atmosphere and seamless visual integration
Built-in RGB led lighting creates sophisticated atmosphere, adding tons of class to your vessel.
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.
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.
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.
