Hertz HPF77XW Portofino 7.7 Inch Marine Coaxial Speaker Pair White

Hertz HPF77XW Portofino 7.7 Inch Marine Grade Flush Mount 2-Way Coaxial Speaker Pair 100W Continuous 200W Peak White with UV Salt and Moisture Resistance

The HPF77XW Portofino from Hertz is a 7.7 inch marine grade flush mount 2-way coaxial speaker pair finished in white, 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, and a fine mesh magnetic grille, the HPF77XW is engineered to resist UV, salt, and moisture for long-term durability in luxury yacht and marine installations. Frequency response spans 45Hz to 25kHz.

Product overview

The HPF77XW is part of the Hertz Portofino marine speaker range, designed for luxury yacht owners who require both Italian-inspired aesthetics and high-performance audio in demanding marine environments. The flush mount ultra-low-profile design integrates cleanly into refined yacht interiors, and the fine mesh magnetic grille attaches securely without tools for a seamless appearance at the mounting location.

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 dynamics and bass depth suited to larger marine cabin spaces. The 36mm tweeter uses a PEI dome and a neodymium magnet for clear, extended high-frequency reproduction. The maximum mechanical excursion is plus or minus 6.65mm at a mounting depth of 108mm.
