More about the product
The Hertz HMS 10BC is a 10-inch marine subwoofer designed for powerful bass and long-lasting durability in harsh marine environments. Built with premium materials and advanced engineering, this model ensures reliable performance for boat audio systems that demand strong low-frequency sound.
The HMS 10BC features a polypropylene cone treated for UV resistance, making it suitable for prolonged exposure to sunlight and saltwater. Its rubber surround provides flexibility and resilience, while the corrosion-proof basket maintains structural integrity even in challenging conditions. The subwoofer is finished in a sleek black design that complements modern marine interiors.
With a power handling capacity of 250 watts RMS and 500 watts peak, the HMS10BC delivers deep, punchy bass that enhances any marine audio setup. It is designed for infinite baffle installation, meaning it can be mounted directly into a boat’s hull without requiring a dedicated enclosure. This simplifies installation while maintaining excellent acoustic performance.
The grille is UV-stable and corrosion-resistant, ensuring it retains its appearance and functionality over time. While the HMS 10BC focuses on durability and sound quality, it does not include LED lighting, which is available on some premium models. Its design prioritises strength and performance, making it a reliable choice for marine enthusiasts who value robust audio output.
Overall, the Hertz HMS 10BC combines marine-grade resilience with impressive bass performance. It is ideal for upgrading a boat’s sound system with a subwoofer that can handle the rigours of marine environments while delivering powerful, clear low-end sound.
