The HMS 10 B2-LD-W is a long-throw 10 inch marine subwoofer engineered for infinite baffle application. The 2 ohm configuration makes the most of amplifier power, relieving the main speakers from reproducing the lowest frequencies and adding bass output and punch to maximise overall system performance. The FEM-optimised high-excursion mobile equipment features a 50 mm (2 inch) voice coil driven by a massive magnetic group, maintaining precise control even at very high SPL levels.
Features
- Engineered and tested for real marine environments: UV, salt-fog, vibrations, water spray, thermal shock and dust.
- Integrated RGB LED lighting, controllable via the HM RGB 1 BK accessory (sold separately).
- Long-throw 50 mm (2 inch) voice coil with polypropylene cone injected with UV inhibitors and co-moulded Santoprene surround.
- Progressive-design aramid fibre spider with silicone-insulated lead wires for durability and consistent performance over time.
- FEM-optimised high-excursion motor driven by a massive magnetic group, encapsulated in a marine-grade polymer injected basket.
- Gold-plated, corrosion-resistant brass connection terminals with silicone cap protecting the leadwire junction point.
- 2 ohm load to maximise amplifier power output.

About the Hertz HMS 10 B2-LD-W
From our tech experts at CEN
Marine-grade 10 inch coaxial speakers handling 300w RMS, built with UV-stable materials and corrosion-resistant hardware for life in sun, salt and spray.
Who it suits
Boats, ribs and open builds, and campers with an outdoor listening area. Anything mounted where rain reaches it should be marine-rated, whatever the vehicle.
Our tech experts advise
In a marine install the wiring decides longevity: tinned cable, sealed joints and a properly fused feed. Mounting position affects the sound more than the speaker choice, because there are no cabin walls to help you. get in touch and we will talk through mounting, wiring and power for your boat.

Frequently Asked Questions
Q: What makes marine speakers different from car speakers?
A: Marine speakers are built with UV-stable, water-resistant cones, grilles and hardware designed for open-air and wet environments. They are the right choice for boats, jet skis, hot tubs and outdoor installs.
Q: Are these speakers fully waterproof?
A: Marine speakers are water-resistant to marine ratings rather than submersible. The IP rating, where provided, is listed in the Specification tab.
Q: Do I need a marine amplifier as well?
A: For best results, yes. Marine amplifiers carry conformal-coated boards that resist moisture and salt air. Match the amplifier to the RMS rating in the Specification tab as you would with any system.
Q: Will these work outside of marine use?
A: Yes. Marine speakers are popular for motorcycles, quads, hot tubs, garden bars and anywhere the weather reaches. Their durability makes them a strong outdoor choice.
Q: Does the HMS 10 B2-LD-W need a box?
A: No. The HMS 10 B2-LD-W is engineered for infinite baffle installation, so it does not need a dedicated enclosure.
Q: How do I control the LEDs on the HMS 10 B2-LD-W?
A: The integrated RGB LED lighting is controlled with the Hertz HM RGB 1 BK accessory, available separately.
Q: Is the HMS 10 B2-LD-W sold as a pair?
A: No. It is sold as a single 2 ohm subwoofer.
