Hertz PORTOFINO 100 S2 10" 2-Ohm SVC Marine Subwoofer - White - Each

The Hertz PORTOFINO 100 S2 marine subwoofer combines deep, controlled bass with a refined flush-mount design suited to premium marine audio systems. Its 10-inch polypropylene cone, 50 mm (2-inch) voice coil, and high-density flux ferrite magnet are designed to deliver dynamic low-frequency performance, with 250W RMS and 500W peak power handling. Available in Black (PORTOFINO100S2C) and White (PORTOFINO100S2W), this subwoofer features a magnetic fine mesh grille for a clean, screw-free finish. With IP65 protection, UV resistance, salt fog resistance, and an infinite-baffle design, it is built for marine installations where durability and streamlined styling matter.

The 10-inch driver and 2-ohm single voice coil configuration provide a solid foundation for low-frequency output in a marine audio system.
