12" Marine Sport LED Subwoofer (2Ω)

The Hertz HMS 12 S2-LD-G is a premium 12" marine subwoofer engineered for high-impact performance in open-air environments. Optimized specifically for infinite baffle (free-air) applications, this subwoofer delivers deep, punchy bass without the need for a dedicated enclosure, making it a versatile choice for a wide variety of vessels. It features a striking integrated RGB LED lighting system within its sport grille, allowing boaters to customize the aesthetic of their sound system to match the mood or style of their craft.

Built to withstand the harshest conditions, the HMS 12 S2-LD-G is Hertz Pure Marine Certified, boasting an IP65 protection grade and full resistance to UV radiation and salt fog (ASTM-D4329/B117 standards). It handles a substantial 500 Watts Continuous (RMS) and utilizes a long-throw voice coil and UV-resistant polypropylene cone to maintain high-fidelity output at high volumes. By offloading the low-frequency work from your main speakers, this subwoofer maximizes overall system efficiency and delivers a powerful, emotive audio experience on the water.
