Sonance Mariner MX66 – Black Marine-Grade Outdoor Speaker
Product Overview
The Sonance Mariner MX66 Black is a 6.5" two-way outdoor speaker built for larger boats, flybridges, and coastal patios that need more coverage than a compact marine speaker provides. It is intended for marine electronics dealers and outdoor AV integrators working on vessels and waterfront properties exposed to salt air and humidity. The headline benefit is marine-grade construction verified to an IP66 rating combined with the output of a mid-size two-way driver set.
Product Description
Positioned between the compact MX62 and the larger MX86 in Sonance's Mariner MX Series, the MX66 pairs a 1.0" ferrofluid-cooled ceramic dome tweeter with a 6.5" Kevlar/Nomex woofer cone and rubber surround, delivering a frequency response of 50Hz to 20kHz at 8 ohms. It carries an IP66 weather rating and is tested to MIL-SPEC 810 for humidity, salt spray, temperature extremes, and UV exposure, which makes it a practical fit for flybridges, swim platforms, and coastal decks. The speaker surface-mounts using Sonance's FastMount bracket system, and a perforated aluminum grille held by the Grille Clip System protects the drivers from spray and debris. Integrators can pair the black MX66 with the matching white finish or with the MX62 and MX86 from the same outdoor speaker family to scale a marine or patio audio system, provided the amplifier's 8-ohm channel rating covers the total number of speakers wired into a zone.
