The HPF77XC Portofino from Hertz is a 7.7 inch marine grade flush mount 2-way coaxial speaker pair finished in black grey, delivering 100W continuous and 200W peak power handling at 4 ohms. Built with marine-grade materials including a polypropylene cone with UV inhibitors, PEI dome tweeter, corrosion-resistant terminals, stainless steel mounting hardware, and a fine mesh magnetic grille, the HPF77XC is engineered to withstand UV exposure, salt fog, and moisture in demanding offshore environments. A dedicated crossover specifically engineered for flush mount integration ensures optimised frequency response and natural vocal presence. Frequency response spans 45Hz to 25kHz.
The HPF77XC is the black grey variant of the Hertz Portofino 7.7 inch marine speaker, designed for luxury yacht owners who require Italian-inspired aesthetics and high-performance audio in demanding marine environments. The frameless flush mount ultra-low-profile design with fine mesh magnetic grille creates a clean aesthetic suited to contemporary marine interiors and dark upholstery installations, with tool-free grille attachment and removal.
The 7.7 inch woofer uses a polypropylene cone with UV inhibitors and a 32mm voice coil over a high-density flux ferrite magnet, providing enhanced dynamics, deeper mid-bass presence, and a broader soundstage suited to larger yacht cabin spaces. The 36mm tweeter uses a PEI dome and neodymium magnet for clear, extended high-frequency reproduction. The dedicated crossover is specifically engineered for flush mount integration to deliver optimised frequency response and natural vocal presence even when the grille is in place. Corrosion-resistant terminals and stainless steel mounting hardware provide long-term reliability in offshore environments.
7.7 inch marine grade flush mount 2-way coaxial design: The 195mm flush mount coaxial driver delivers 2-way sound reproduction in a single mounting location, suited to luxury yacht and marine cabin installations where space and aesthetics are priorities.
Black grey finish for contemporary marine interiors: The black grey colour and frameless flush mount architecture suit contemporary marine interiors and dark upholstery installations, providing a clean, refined aesthetic with the fine mesh magnetic grille.
