More about the product
The Hertz HMS10B is a premium marine subwoofer designed to deliver deep, powerful bass in open-water environments. Built for durability and performance, this 10-inch subwoofer combines robust materials with advanced acoustic engineering to ensure consistent sound quality even in harsh marine conditions.
The HMS10B features a polypropylene cone reinforced with UV-resistant materials, making it ideal for prolonged exposure to sunlight and saltwater. Its rubber surround enhances flexibility and longevity, while the high-excursion design allows for impressive low-frequency output. The subwoofer is housed in a corrosion-resistant basket, ensuring structural integrity over time.
With a power handling capability of up to 250 watts RMS and 500 watts peak, the HMS10B provides strong, punchy bass that complements any marine audio system. It operates at 4 ohms impedance, making it compatible with a wide range of amplifiers. This model is designed for infinite baffle applications, meaning it can be mounted directly into a boat’s hull without requiring an enclosure. This simplifies setup while maintaining excellent acoustic performance.
Installation is straightforward thanks to its versatile mounting options. The HMS10B is finished in a sleek black design that blends seamlessly with modern marine interiors. Its grille is UV-stable and corrosion-proof, ensuring it retains its appearance and functionality over time. While the subwoofer excels in durability and sound quality, it does not include built-in LED lighting, which some higher-end models offer for aesthetic enhancement.
Overall, the Hertz HMS10B is a reliable choice for those seeking robust bass performance on the water. It combines marine-grade resilience with impressive audio output, making it a standout option for upgrading any boat’s sound system.
