Hertz PORTOFINO 100 S2 10" 2-Ohm SVC Marine Subwoofer - Each
Hertz PORTOFINO 100 S2 is built for yacht owners who want deep, controlled bass without compromising the clean, sophisticated look of a luxury vessel. Designed with a flush-mount 10-inch architecture and a powerful 2 ohm single voice coil configuration, this marine subwoofer blends effortlessly into premium interiors while delivering the kind of low-frequency impact that transforms every listening session on the water.
Available in both black and white finishes, the Hertz PORTOFINO 100 S2 gives builders and boat owners the flexibility to match modern marine aesthetics perfectly. The black PORTOFINO100S2C adds a bold contemporary touch, while the white PORTOFINO100S2W complements bright, elegant yacht interiors.
Deep Bass Designed for Open Water
Out on the water, sound behaves differently. Open-air environments can swallow weak bass like waves disappearing into the horizon. That is why the Hertz PORTOFINO 100 S2 is engineered specifically for marine performance. With 250 watts RMS and 500 watts peak power, it produces rich, dynamic bass that stays controlled and musical even in challenging outdoor conditions.
The 10-inch polypropylene cone with UV inhibitors helps maintain accurate low-frequency response while standing up to years of sun exposure. Combined with a high-density flux ferrite magnet and a 2-inch voice coil, the result is powerful output with impressive balance and precision.
Flush-Mount Luxury Styling
The Hertz PORTOFINO 100 S2 is more than just a marine subwoofer. It is part of a carefully crafted luxury audio system designed for high-end yachts and premium marine environments. Its ultra-low-profile flush-mount design creates a seamless appearance that feels integrated instead of added on.
The fine mesh magnetic grille delivers a clean, screw-free finish that looks refined from every angle. It attaches securely without visible hardware, preserving the sleek aesthetic expected in modern yacht interiors. Want bass that performs without dominating the visual space? This design handles that beautifully.
Built for Real Marine Conditions
Salt, moisture, and constant UV exposure can be brutal on marine electronics. The Hertz PORTOFINO 100 S2 is built to face those conditions head-on using premium marine-grade materials tested for long-term durability.
Its IP65 certification confirms protection against water jets, while ASTM-compliant UV-resistant materials help prevent damage caused by prolonged sun exposure. Hertz also subjects the subwoofer to extensive salt fog testing based on ASTM-B117 standards to ensure resistance against corrosion in harsh marine environments.
From marina cruising to long offshore journeys, the Hertz PORTOFINO 100 S2 is engineered to maintain consistent performance season after season.
Designed for Infinite-Baffle Applications
One of the standout advantages of the Hertz PORTOFINO 100 S2 is its infinite-baffle design. Since no dedicated enclosure is required, it integrates more easily into premium yacht layouts while still delivering strong, authoritative bass response.
This approach helps preserve valuable space and simplifies clean installations without sacrificing low-end performance. Think of it like hidden power beneath the deck — always present, always controlled, and never intrusive.
Italian Design Meets Marine Engineering
The Portofino line reflects Hertz Marine’s focus on combining elegant Italian styling with serious acoustic engineering. Every detail of the Hertz PORTOFINO 100 S2 is created to complement luxury vessels while maximizing sound performance in open-air environments.
Minimal visual impact, durable marine construction, and impactful bass all come together in a subwoofer that feels purpose-built for refined marine audio systems. Pairing seamlessly with Hertz Marine amplifiers, it delivers the dynamic playback expected from premium yacht audio.
