About the Fusion MS-OS420

Plenty of mounting options

Fusion's MS-OS420 box speakers are the ideal choice for an alloy-hulled vessel, where flush mount speakers aren't a great choice for a lot of reasons. The adjustable mounting bracket makes them much easier to install using the included hardware. And, of course, that hardware also comes in handy if you're mounting these speakers on a porch, patio, or dockhouse.

FOCAL MS-OS420

Mount them horizontally or vertically

These rugged, versatile speakers are designed and manufactured with weather in mind, so they can stand up to just about anything, all year long. The sealed box keeps the elements out, while the white finish won't succumb to punishing sunlight.

Built tough, for land or sea

Ordinary speakers have it easy – they just have to sound great. Marine speakers, on the other hand, have to sound great AND stand up all to the extremes of life on a boat – water, wind, heat, humidity, dust, pollen, birds, and (depending on where the boat is docked) freezing cold.

Come to think of it, that's pretty much what a set of outdoor speakers have to go through, too. That's why these speakers are a great choice for your boat or your backyard.

Features

Wire Terminals: Each enclosure has spring terminals that will accept bare wire up to 12 gauge.

Mounting Brackets: The included aluminum C-brackets securely mount the speakers to almost any flat surface and offer placement flexibility. The speakers can be mounted horizontally, vertically, or at an angle. The brackets allow you to rotate the speakers almost 90° each direction (almost 180° total) after they've been mounted, letting you direct the sound to deliver the best possible sound in a variety of situations.

Note: If you remove the bracket, the M5 threaded inserts for the bracket's knobs can be used with 3rd party mounting brackets.
