Hertz 78035451 HMS 10 S4-LD-SW.1 10" Marine Subwoofer

Hertz 78035451 HMS 10 S4-LD-SW.1 10" Marine Sport Subwoofer (4-Ohm / 600W Peak)

The Hertz 78035451 (Model: HMS 10 S4-LD-SW.1) is a high-performance 10-inch (250 mm) 4-Ω marine subwoofer designed to deliver deep, dynamic low-frequency reproduction in harsh open-water environments. Engineered primarily for infinite-baffle (free-air) applications, the HMS 10 eliminates the necessity of a dedicated acoustic enclosure, allowing direct installation into boat gunwales, seat bases, or transom bulkheads.

Built with a UV-inhibited polypropylene cone, Santoprene surround, and a massive ferrite magnetic structure housed inside an IP65 marine-grade polymer basket, the speaker withstands UV exposure, salt fog, spray, and thermal shock (ASTM-B117 / ASTM-D4329 tested). This variant features an integrated multicolor RGB LED lighting array embedded behind a removable white sport grille, along with gold-plated corrosion-resistant brass terminals protected by silicone caps.

Key Features

• Infinite-Baffle Optimized: Specifically tuned motor structure and suspension deliver high acoustic output and low distortion without requiring a sealed enclosure.

• Built-In RGB LED Lighting: Integrated lighting system illuminates the cone area through the white sport grille.

• Extreme Marine Weatherproofing: IP65 water-jet resistant with UV inhibitor-infused polypropylene cone and salt-fog proofing (ASTM-B117).

• High Excursion Motor Assembly: Long-throw 50 mm (2'') voice coil and progressive aramid-fiber spider provide continuous mechanical control.

• Corrosion-Resistant Hardware: Features gold-plated brass spade terminals encased in protective silicone boot caps.
