Aqua Signal 84500-7 Series 84 Forward-Facing Diaphragm Horn, Black Housing, 110-112 dB, 12 Volt

The Aqua Signal 84500-7 is a forward-facing diaphragm-style horn from the Series 84 lineup, built as a single horn for use in a dual-tone horn setup aboard a boat. It produces a sound output of 110-112 dB, giving it enough volume to serve as an effective signaling horn in marine environments where audibility across open water and over engine noise is essential. The horn runs on a 12 Volt electrical system, matching the standard DC voltage found on most recreational and small commercial vessels.

Construction features a stainless steel housing finished in black, giving the horn corrosion resistance for exposure to a marine environment along with a low-profile appearance that blends into most helm and bow mounting locations. The forward-facing design directs sound output ahead of the vessel, which is the typical orientation for signaling to traffic in the vessel's path. Overall dimensions are 8 x 4 x 6.5 inches and the unit weighs 0.65 pounds, making it a compact, lightweight accessory that does not add meaningful load to a mounting bracket or bulkhead.

This horn is intended as a direct-fit replacement or addition for boats already equipped with, or being upgraded to, an Aqua Signal Series 84 horn system, and it is designed as a universal fit across applicable boat types rather than being limited to a specific make or model.
