Marine subwoofer. HMS 10 B4-LD-C

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 leadwire junction point.
