Please read on for me details on how to pick the best speakers.

Difference between marine speakers and regular speakers

When you read about marine speakers, you may think they are just the same as regular speakers. This could not be further from the truth.

Unlike regular speakers, marine speakers are built to withstand everything the ocean can throw at them – from UV rays and salt to hurricanes and tsunamis.

They are also specifically designed to reproduce music at lower volumes, so you never have to worry about disturbing the peace when you’re cruising the high seas.

The marine speaker has been designed to withstand extreme conditions. These speakers are specifically designed to be waterproof, so they can be used in the marine environment.

A marine speaker comes with a mount, and this can be placed on the wall or on the ceiling of the boat.

Types of Boat Speakers 

There are different types of marine speakers in the market. As it is usual with most products, the biggest challenge is getting the best from a host of product brands.

First, there is the double cone speaker type that features single drivers but has two cones. One is big, and the other is small, which allows the system to deliver high and low frequencies.

The other type is the coaxial marine speakers, which go by the name 2-way or 3-way speakers. This type has multiple drivers for the finest production of sound.

Again, a subwoofer type of boat speakers is also available. These are not the conventional subwoofers that you have at home. These are specifically molded for the marine environment.

Finally, there are marine-grade sound bars that you can use on your boat without the need to bore holes for installation.

In the same breath, marine speakers come in a variety of sizes. For example, 6.5″ marine speakers happen to be the most popular size while 4” speakers are said to be compact. 

So, you have to consider what size will be best for your yacht depending on size and the required mounting depth. Don’t fail to use the correct wires for marine speakers during installation.

Having said that, let’s focus on how you can get the best 6.5” marine speakers.

What to Consider

  • Water resistance

This point may sound obvious, but it isn’t. Not all products sold for marine use are what they claim to be. This is why you need to go for reputable brands. Specifically, you need to verify that the speakers you choose are water-resistant.

For the best marine speakers, all electronic parts need to be in a sealed watertight unit.

  • Interior vs. Exterior Use

The other equally important factor to consider is whether you want the speakers for interior or exterior use. First, any equipment that has to be used for the maritime purpose, whether interior or exterior, has to withstand high humidity.

All the same, those to be used on the exterior have to be toughly built since they face all elements. The metallic parts need to be from metals that don’t rust..

On the other hand, parts that have to face the sun must be UV protected, or they will quickly get damaged.

All the same for marine speakers for interior use don’t have to be as hardy as those for exterior use. Consequently, internal marine speakers need to be mold resistant and withstand high levels of dampness. 

  • Audio Quality vs. Volume

Are you after high-quality sound, or after loud volume? Some manufacturers focus more on sound projection, therefore working to produce loud sounds. On the other hand, other companies emphasize the quality of sound produced by reducing distortion. 

As for you, you any need to decide which one matters more to you and pick your best marine speakers

  • Power Handling

To ensure that you have the best marine speakers onboard, consider their power handling ability. Notably, speakers have peak wattage and continuous wattage (RMS). Unfortunately, some manufacturers will only display the peak since it shows a bigger number.

If you want to have your system safe, especially if you have to use an external amplifier, verify the RMS of the speakers before you purchase them. Both rating are equally crucial in determining which speaker you need to settle on.

If you don’t intend to use an amplifier, then you don’t need marine speakers with so high ratings. 

  • Budget

Finally, your budget is key to what you can get and what you can’t. All the same, affordable doesn’t imply cheap quality by any standards.

Actually, the amount of money you are willing to spend is among the first considerations you need to make.

Despite the budge, get some good boat speakers that will pump life into your boating experience.

What are the Best 6.5” Marine Speakers

In case you have always desired to get the best 6.5-inch marine speakers, you need to be keen on the brand that you choose. Unfortunately, some manufacturers usually fail to give all the specifications. For example, some will only quote the peak power handling and fail to disclose the RMS.

The other factor you need to look at when choosing the best boat speakers is whether they can withstand the harsh environment at the ocean.

Also, different types of speakers will produce various sound qualities. Therefore, you need to decide on what type works best for you. You need to be specific on what you value most; volume or quality of sound.

Finally, go by your budget. Affordable doesn’t always mean compromised quality. Therefore, choose the best marine speakers that fit your budget and enjoy the best music during your boating sessions.
