Sonance Mariner MX66 – White Marine-Grade Outdoor Speaker

Product Overview

The Sonance Mariner MX66 White is a 6.5" two-way outdoor speaker sized for larger boats, wraparound decks, and coastal patios that need more output than a compact marine speaker can deliver. It is intended for marine dealers and outdoor AV integrators outfitting vessels and waterfront properties that face constant salt air and moisture. The headline benefit is a larger-format Mariner MX speaker built to survive marine conditions while filling bigger outdoor spaces with balanced sound.

Product Description

The MX66 sits in the middle of Sonance's Mariner MX Series, between the compact MX62 and the larger MX86, giving integrators a mid-size option for flybridges, swim platforms, and generously sized patios. It pairs a ferrofluid-cooled dome tweeter with a Kevlar/Nomex woofer cone in the same enclosure footprint as the MX62, aimed at slightly wider dispersion and output for larger coverage areas. Like the rest of the Mariner MX line, it mounts to a surface using Sonance's FastMount bracket system and is protected by a perforated aluminum grille secured with the Grille Clip System. The white finish is intended for light-colored hulls, railings, and stucco or coastal exteriors, and the MX66 White can be combined with the black MX66 or with MX62/MX86 models from the same outdoor speaker family to build out a multi-zone marine or patio system. As with any outdoor install, confirm the amplifier's channel count and impedance rating before wiring multiple Mariner MX speakers together.
