Marine - Marine Subwoofers

Sport grille, featuring built-in LEDs, can be easily removed to be painted with the perfect color for your vessel. HMS subwoofers are designed to be installed without the need for a dedicated enclosure delivering powerful and precise bass in any vessel. 
The motor and suspension design are optimized for high-power, infinite-baffle operation featuring long linear excursion capability for tremendous output with low-distortion. 
Hertz Marine subwoofers not only add tons of bass output to your system but also relieve the main speakers from the hard work of reproducing the lowest frequency range, maximizing the overall system performance, for unlimited sound pressure and emotion! 

The HMS 10 B long throw 10” marine subwoofer, also available in the black option HMS 10 B-C, is engineered for infinite baffle application. It relieves the main speakers from the hard work of reproducing the lowest frequency range, adding bass output and punch to maximize the overall system performance. The FEM optimized high-excursion mobile equipment of HMS 10 B with a 50 mm (2”) voice coil is driven by a massive magnetic group, to obtain a perfect control also at very high-level SPL. Engineered and tested for the real environment of application (UV, salt-fog, vibrations, water spray, thermal shock, dust) HMS 10 B is nature-proof. The progressive design aramid fiber spider with silicone-insulated lead wires ensures durability and constant performance over time. The gold-plated corrosion resistant brass connection terminals with silicone cap protect the lead wire junction point.
