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.

I'm tremendously pleased with this purchase and the professional service that has been common with every dealing I have had with your business . I will continue to promote you as I have since the 70's thanks again for your excellent service.

Pros: I'm able to walk the perimeter of my 1+ acre lot and clearly hear each note being played through these speakers at a moderate sound level

Cons:

Pretty hard to beat - they are not audiophile quality- I'm very impressed with how well these sound- given the price and the all weather capability. Find a good spot to place them to acoustically increase the lower end (which is already not terrible), and you'll have nice all weather sound!

Pros: Price. Good clean sound

Cons:

I am moving to a new house and was looking to swap out my expensive outdoor speakers with something reasonably priced. Was pleasantly surprised with the sound quality of these speakers given the reasonable price. Quite a bit of bass response from a small package. Can't rate how these speakers will hold up outside as they were installed a few weeks ago but based on sound quality, a great value for the money. Also very easy to install for a do-it-yourseler with minimal speaker experience.

Verified employee purchase (What's this?)

These are marine speakers. Installed them on my sailboat. I connected them up and initially they worked fine. However, the second day I turned them on, one of the speakers was not functioning. I discovered that the gripping mechanism for the speaker wire had failed. Since this is a spring loaded type of grip, when it failed, it rendered that speaker useless.

Pros: Marine construction

Cons: Poor speaker wire connection mechanism

boat speakers

ordered these speakers for my boat and they work great so far. Time will tell as to durability.

Pros: These speakers fit exactly the way I expected them to and enhanced the sound of my very cheap stereo system in my boat.

Cons:

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.
