Sonance Mariner MX52 SST – Black Marine Outdoor Speaker

Product Overview

The Sonance Mariner MX52 SST Black is a compact 5.25" outdoor speaker built for smaller boats, tight deck spaces, and coastal patios that still require marine-grade durability. It is aimed at marine installers and outdoor integrators who need a space-saving speaker verified to an IP66 weather rating. The headline benefit is a smaller footprint that does not compromise on outdoor durability.

Product Description

The MX52 SST is the compact entry point in Sonance's Mariner MX Series, pairing a 0.75" ferrofluid-cooled cloth dome tweeter with a 5.25" textured polypropylene woofer and Single Stereo Technology to deliver coverage from a smaller enclosure than the MX62, MX66, or MX86. It carries an IP66 weather rating and is tested to MIL-SPEC 810 for humidity, salt spray, temperature extremes, and UV exposure, at 87dB sensitivity and an 8-ohm load. Like the rest of the line, it surface-mounts with the FastMount bracket system and uses a perforated aluminum grille held by the Grille Clip System. Integrators can pair the black MX52 SST with the white finish, or scale up to larger Mariner MX models from the same outdoor speaker family for zones that need more output, while confirming the amplifier's 8-ohm channel capacity for the full number of speakers wired into a zone.
