Benefits of Marine Speakers

  • Waterproof. Perhaps the most obvious and important benefit of marine speakers is that they are waterproof. Since the speakers are meant to be used on open water, look for them to feature a quality waterproof rating for the best protection.
  • Versatile. Another important benefit of marine speakers is that they are versatile. Since they are waterproof, most marine speakers can also be used on your RVs, campers, and off-road vehicles like ATVs, UTVs, and dirt bikes.
  • Durable. Marine speakers are typically extremely heavy-duty, durable products. It is essential that marine speakers are built from high-quality materials that are rust-resistant, corrosion-resistant, and can withstand the test of time.

Types of Marine Speakers

Dual Cone

If you are shopping on a budget, dual cone marine speakers are typically the cheapest type of speaker, but they are also the lowest quality of all three types. Dual cone speakers feature one speaker driver alongside two cones to reproduce the sound. While there are some quality dual cone speakers available on the market, if price is not a major factor, you may want to consider one of the other types of speakers for the best audio quality.

Coaxial

Coaxial marine speakers are most commonly referred to as two-way or three-way speakers. In this type of speaker, one speaker is wrapped around another speaker. Coaxial speakers are typically higher quality than dual cone speakers, but they are also more expensive. One downside of this type of speaker is cross-phase distortion, which occurs because the speakers are so closely attached.

Component

Component marine speakers are typically the most expensive, but also the highest quality of all three types of marine speakers. Component speakers are very similar to coaxial speakers, but their design eliminates any chance of cross-phase distortion. This type of speaker features a tweeter that is completely separated from the woofer cone, replicating the design of most box speakers.

Top Brands

Sony

Founded in 1946 and headquartered in Tokyo, Japan, Sony is an international company known for manufacturing high-quality consumer and professional electronic products. In addition to high-quality marine speakers, Sony produces televisions, video cameras, smartphones, vehicle receivers, and more.   

Boss Audio

Founded in 1987 and headquartered in California, Boss Audio has developed into one of the most reputable audio and video manufacturers in the United States. In addition to high-quality marine speakers, Boss Audio produces car stereos, all-terrain speakers, Bluetooth remotes, and more.  

Polk Audio

Founded in 1972 and headquartered in San Diego, Calif., Polk Audio has developed into one of the top American manufacturers of home speakers, automobile speakers, and a wide range of other electronic products. In addition to high-quality marine speakers, Polk Audio produces floor speakers, soundbars, home speakers, outdoor speakers, and more.  

Marine Speaker Pricing

  • Under $50: Marine speakers in this price range are available at an excellent value. Marine speakers at this price point are typically dual cone speakers, so if you are looking for the highest quality audio, you may want to consider another option.
  • $50-$100: This is the most common price point for marine speakers. Products in this price range are typically high quality, waterproof, reliable, and they can be either the coaxial or component speaker types.
  • $100 and up: Marine speakers in this price range are priced at a premium. Products in this price range are typically the highest quality, component speaker types, are built from durable materials, and come with an excellent waterproof rating.

Key Features

Power

Owning a set of marine speakers that generates a sufficient amount of power is an important consideration. In general, your marine speakers should be able to have an equal amount of power or more than your boat's stereo or amplifier can provide. The amount of power is typically measured in RMS or continuous wattage. The higher the number, the more important it is to know the amount of power your speakers can handle.

Sound Quality

The sound quality of your marine speakers is another important feature to consider. If you will be using your speakers primarily for fishing or while trolling around, then the sound quality and volume are probably not as important as if you will be using your speakers for entertainment or while cruising around. Most of the best speakers available on the market will have the ability to project sound well and produce a lot of volumes.

Rating

The waterproof rating is another essential factor to consider when shopping for your marine speakers. In general, the higher the rating the more protection it will provide. Waterproof speaker ratings are scored on a scale from one to seven, with a rating of one offering no special protection, and a rating of seven offering protection from condensation, water droplets, strong waves, rain, and more.

Other Considerations

  • Installation. The type of installation and size of your installation are important considerations for your marine speakers. Depending on the size and shape of your boat, a different size speaker may be a better option to best fit your needs. Make sure to measure the size of your speaker hole and the depth of the hole to make sure your new speakers will fit before beginning the installation process. 
  • Budget. Understanding your budget and the price of each type of speaker are important considerations. If you are shopping on a budget, you can still find a quality set of speakers. But if pricing is not an option, then you may want to opt for speakers of the highest quality, like component speakers. Some speakers are even available to purchase in value packs of up to four speakers in one set.
  • Warranty. The length and type of warranty are important factors to consider with your marine speaker purchase. Most of the best speaker and electronics manufacturers will offer some type of warranty or limited warranty with their products. Look for a warranty to at least cover any type of manufacturing defects or issues with your marine speakers upon delivery, as well as any issues you may have in the first few uses of your new product.

Tips

  • Make sure to purchase a set of marine speakers that fits your specific needs. Depending on whether you will be using your speakers for activities like entertainment or fishing will affect the type and size speaker you may need.   
  • Install your speakers in the best spot of your boat to produce the highest sound quality and the best acoustics. In general, this will be toward the back of your boat, but it can vary greatly depending on the type and size boat you own.
  • Make sure that your speakers feature a high waterproof rating. No matter the price or type of speakers you purchase, you will want a set of speakers that can hold up when wet and in almost any condition.

  • Keep in mind when looking for your marine speakers that bigger is not always better. Shop for features like power rating and waterproof rating when looking for your new speakers, and not necessarily the size of your speakers.
