Hertz HMS 10 S4-LD-G 10" 600W 4-Ohm Marine RGB LED Subwoofer - Grey (HMS 10 S4LDG)

The Hertz HMS 10 S4-LD-G marine subwoofer delivers powerful, controlled bass in a design built for life on the water. Featuring a 10-inch driver, 300W RMS power handling, and 600W peak power, it adds depth and impact to your marine audio system. Integrated RGB LED lighting and a paintable sport grille provide a customizable look to complement your boat.

The HMS 10 S4-LD-G is designed for infinite baffle installations, allowing it to operate without a traditional subwoofer enclosure. This space-saving design is ideal for marine audio systems where installation space is limited.

Built to handle demanding marine conditions, this subwoofer features IP65 protection and components designed to resist UV exposure, salt fog, and corrosion. Its marine-grade construction helps maintain reliable performance through exposure to sun, moisture, and saltwater environments.

Integrated RGB LED lighting adds customizable illumination behind the sport grille. The removable grille can also be painted to match your boats style, making it easier to coordinate the subwoofer with your marine audio setup.

With 300W RMS power handling, 600W peak power, and a 4-ohm impedance, the HMS 10 S4-LD-G delivers strong low-frequency output for marine audio systems. Its 50mm (2-inch) long-throw voice coil and 140mm ferrite magnet support high-output performance, while its ±19mm mechanical excursion and 13.5mm Xmax help maintain controlled cone movement.

The subwoofer uses a UV-resistant polypropylene cone, co-molded Santoprene surround, and progressive aramid fiber spider to support durability and controlled movement. Silicone-insulated lead wires and a polymer-injected marine-grade basket provide additional resistance to vibration and harsh marine conditions.

By handling low-frequency output, the HMS 10 S4-LD-G helps complement your full-range marine speakers, allowing them to focus on midrange and high-frequency detail. Its 41Hz resonant frequency, 88dB sensitivity, and 0.71 Qts value support its low-frequency performance and system integration.
