Hertz HMS 10" Sport LED Marine Subwoofer — 600W Peak / 300W RMS

Experience bone‑rending bass on the water with the Hertz HMS 10" Sport LED Subwoofer, engineered specifically for marine environments. Delivering 300 watts of continuous power and 600 watts peak, this compact sub delivers deep, controlled low end without the need for a dedicated enclosure. Its infinite‑baffle design makes it a versatile fit for a wide range of vessels, from center consoles to cruisers, freeing your main speakers to shine with cleaner, more dynamic midrange and highs.

Why the HMS 10 stands out on the water

• Evergreen, space‑savvy bass: Infinite‑baffle operation means you can mount this sub without a bulky enclosure, maximizing cabin or cockpit space while still delivering powerful, room‑filling bass.
• Sport LED grille for visibility and style: The white sport grille with integrated LEDs not only looks striking in bright day light or dusk, but is also paintable to match your boat’s color scheme for a seamless installation.
• Robust, marine‑grade construction: A 50 mm voice coil paired with a high‑density ferrite magnet handles high power with precision, while a UV‑inhibited polypropylene cone resists sun exposure and harsh spray.
• Dedicated power handling: 300 W RMS continuous power and 600 W peak ensures you get serious bass punch on track‑heavy music, even when the deck is buzzing with other activities.
• Optimized for long‑throw bass: The motor and suspension are tuned for high power handling and extended linear excursion, yielding deep, authoritative low frequencies with minimal distortion.
• Straightforward installation depth: With a compact depth of 116 mm (4.56 in), the HMS 10 is easier to fit into tight dash panels, boat walls, or under seating where space is at a premium.
• Reliable power in a 4 Ω load: The 4 ohm impedance pairs well with a wide range of marine amplifiers, delivering efficient power transfer and solid headroom under demanding listening sessions.

The HMS 10 is purpose‑built for marine electronics environments, a category where space, durability, and power handling converge. By taking the bass load off your main speakers, it preserves clarity and dynamic range across the entire system—so you can enjoy crisp highs, tight mids, and thunderous lows even in open‑air or noisy marina settings.

Ideal use cases and setup tips

• Small to mid‑sized vessels where enclosure space is at a premium, including center consoles, bow riders, and sailboats.
• Install behind seating panels or under cockpit storage where a shallow depth helps maintain cruise comfort and cargo space.
• Pair with a marine‑rated amplifier on a 4 Ω load to harness the HMS 10’s power capacity without overdriving other speakers.
• Sport LED grille provides a contemporary look; if you’re matching a color scheme, consider a light‑sand or charcoal paint to blend with your boat’s interior.

Durability and maintenance on the water: Rinse with fresh water after salt exposure, and wipe the cone and grille to prevent salt buildup. The UV‑inhibited cone and robust magnet design are built to withstand prolonged sun exposure, keeping bass tight and listening fatigue low even on long days at sea.

With the Hertz HMS 10" Sport LED Subwoofer, you’re choosing a marine‑savvy solution that aligns power, durability, and aesthetics. It’s a confident step up for any marine audio system, delivering the kind of impact that makes every voyage feel like a premiere.
