Inspired by the elegance of the Italian Riviera, the PORTOFINO 65 XC delivers a soundtrack worthy of the world’s most exclusive yachts. This 6.5-inch flush-mount marine coaxial speaker combines premium acoustic performance with a bold, refined black finish, designed to integrate seamlessly into contemporary yacht interiors and dark upholstery installations. The ultra-low-profile architecture and fine mesh magnetic grille create a clean, frameless appearance with minimal visual impact. Every detail has been engineered for both aesthetics and performance, including a dedicated crossover specifically developed for flush-mount installation, optimizing frequency response and ensuring natural, balanced sound even behind the grille. Built with true marine-grade materials, the PORTOFINO 65 XC is resistant to UV exposure, salt fog, and moisture, compliant with stringent marine standards for long-term durability. Corrosion-resistant terminals and stainless steel mounting hardware guarantee reliability even in harsh offshore conditions. With smooth, wide dispersion from its concentric tweeter design and dynamic output capability, the PORTOFINO 65 XC transforms every journey into an immersive audio experience. With the PORTOFINO line, Hertz Marine unites Italian design, engineering excellence, and outstanding value, setting a new benchmark in premium flush-mount marine audio.

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.
