I’ve researched speakers and found 9 epic marine speakers sure to provide the sound you want.

Are there any great marine speakers available? Yes!  There are hundreds of options for marine speakers to fit any budget.

With a little knowledge under your belt about what is available, you’ll have no problem choosing the best speakers for your boat. Marine speaker systems have come a long way in terms of sound quality, build quality and durability.

There was a time, not too long ago, when it was tough to find a good marine speaker system that wouldn’t have problems with water getting into the housing or rusting.

Over the years though, the quality of materials and construction has only improved. Now you can find great sounding speakers that are waterproof or water-resistant and will last for years without any trouble.

What makes a great marine speaker?

Speakers are generally graded on construction quality, sound quality, and the materials used to build them. Marine speakers aren’t any different in how they are graded, but to be a great marine speaker, there are a couple of other things to consider – water resistance and durability in harsh conditions.

Marine speakers are met with some unique challenges that other speakers don’t have to deal with.  They are exposed to all kinds of weather conditions, often getting wet either by rain or because they are splashed, and they are often subjected to salty air conditions.

To better understand why creating a water-resistant or waterproof speaker that will stand up well to all types of harsh conditions and still provide good sound quality is challenging, it’s helpful to understand how speakers are made.

A speaker is made by having a permanent magnet that is held firmly in place with an electromagnet that’s attached to a cone made of flexible material placed in front of the permanent magnet. When electrical currents pass through the electromagnet, the poles of the electromagnet are quickly changed to attract and repel the electromagnet to the permanent magnet.

As this happens, vibrations pass through the cone and are propelled into the air creating sound. On a typical speaker, water, salt air, direct exposure to sunlight, and changes in temperature could damage the cone and the electrical components either reducing the sound quality or making the speaker inoperable.

Marine speakers, however, are made using heavy-duty materials so they will stand up to the harsh environments they spend their time in – the cone is made out of more durable material, the metals used are rust and corrosion resistant, all of the inputs must be sealed with rubber gaskets, and the circuitry board is sealed to prevent water from damaging the electronics. 

A great marine speaker is one that is waterproof, durable, and produces a good sound.

Here are a few of the best marine speakers available:
