HMS 10 B4-LD-W 250 (10) mm (in.) | 191 (7.52) mm (in.) | Subwoofer | 600 W | 4 Ohm | Single Voice Coil

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 B4-LD-W 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.

Technologies
HMS 10 B4-LD-W
IP 65 CERTIFICATION

HMS 10 B4-LD-W
WATER JET TESTED

The protection grade IP65 for speakers define all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.

HMS 10 B4-LD-W
UV RESISTANT

According to the severe ASTM-D4329 standards for UV resistance, all the materials used for Hertz Marine products are designed to face long time exposition to UV radiations while cruising on the open sea.

HMS 10 B4-LD-W
SALT FOG TESTED

To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.
