The Best Boat Speakers and Marine Audio – Ultimate Buyer’s Guide

Originally posted on


Got a new boat? Congratulations! You likely love your boat and chances are, you want to trick it out with great marine speakers.

That said, you can’t slap on the first set of speakers you find in the market.

Saltwater corrosion is the biggest enemy of a boat speaker. Other factors like pressure and constant physical friction with the water can also damage poorly designed speakers.

If you’re looking into buying new boat speakers, you need to know which ones to look for.

In this guide, we’ll give you everything you need to know to get the best marine speakers you can buy. What should you look for? Which brands are great for both function and budget?


When choosing the right marine speakers, there are a few factors that you should consider. The best units have the same factors. A quick list of these are:

  • Marine speaker durability
  • Speaker audio quality
  • Power and impedance
  • Marine speaker sizes

All these are crucial factors you need to take into account.


When looking for boat or wakeboard tower speakers, you need to confirm durability. They need to have the right level of waterproofing to prevent rusting and corrosion. You also would want them to handle other types of outdoor elements.

As we noted, saltwater can increase rusting and corrosion in your speakers. When you combine this with the salty air, it can create a significant impact on speaker lifespan. UV rays from sunlight can also disintegrate plastics and adhesives.

You want durable marine speakers that can stand the outdoors.


Speaker audio quality is no brainer. Apart from the wattage and impedance, you want to get crisp, clear audio. You may have the best audio in the world but sub-standard speaker audio quality will get you.

Make sure your speaker audio works according to your preferences.

Some like their bass to come from both speakers. Some people rather have their marine speakers play only highs and mids. This leaves the lows to their subwoofers.

Make sure that you have the right setup that caters to your audio preferences.


Power and impedance are crucial for boat speakers. These will help you choose the type of amplifier you need. Why?

Power is the ability of your speakers to receive power from amplifiers before it receives damage. If a speaker drives too hard and hot, you can create permanent damage to your speakers.

Impedance will allow amplifier matching to get easier.


Marine speaker sizes are vital when you are outdoors. Bigger means better performance in the world of speakers, so that’s a no-brainer. Even then, there’s an important reason why you want to put size as a factor.

As a boat speaker set is directional, a bigger unit will help the audio cope with the environmental acoustics. The lack of a hard environment for the audio to bounce can exacerbate bad audio. Having strong audio in the first place will give you a better time.


What are the best marine speakers for you? Here are a few of the best units out there.

1. DS18 NXL-62TD-BK Black Tower Speakers 750W Marine

The DS18 NXL-62TD-BK Black Tower Speakers 750W Marine are one of the best 6.5 speakers out there. It’s 750W of full directional audio, which will do a nice audio dissipation around your boat. The 4-ohm impedance means you can crank up the audio with the right amplifier.

What we love about the NXL-62TD is that it comes with a 1.35-inch titanium diaphragm compression driver. This will create a better stereo separation for your audio, making the sound more “environmental”. This means there’s better sound staging, allowing for crisper, more discernible audio.

What sets the DS18 HYDRO CF8 apart is the durability and power. Each speaker has a 450W peak power, with an RMS power of 150 W each. With the right amplifier, you can pull more power to crank the audio up and enjoy good beats.

The HYDRO CF8 has the same IP65 rating as the NXL-62TD even if they’re in different leagues. The body comprises of high-grade carbon fiber with metal mesh with UV specifications. This means you can lavish under the bright sun, get wet and you’ll still get the best audio out there.
