The 9 Best Sounding Marine Speakers for All Boats

Whether good music lulls you to sleep, soothes your worries or gets your groove on, the fact is that it won’t induce the right feeling if it doesn’t come from an excellent source. An efficient speaker works great when enjoying music from mobile devices. However, the same cannot be said for outdoor activities like sailing or a sea cruise. You need a speaker specially designed for marine use. It will do justice to your favorite tunes and make your marine experience memorable.

There are many types of boat speakers, with different designs, capacities, and sizes. Some are ideal for indoor use while some are more suited for the outdoors. The quality differs depending on the brand and features. Some have better resistance to weather conditions than others.

Given the variability in the different models, identifying a ​speaker that best suits your needs can prove an overwhelming task. This post seeks to make the search easier by reviewing the best marine speakers. But first, we discuss important factors to consider when shopping for a boat speaker.

Before we get into the Buyers Guide here’s a list of ​what we believe to be some of the best boat speakers.

Features to Look for in ​High Quality Marine Speakers


There are two main types of marine speakers, i.e., recess and tower speakers. Recessed speakers are designed for installation in a panel, on the dashboard, ceiling or wall of the boat.

Tower speakers are more powerful and usually attach to the wake tower. If the goal is to blast music in the direction of a friend who’s skiing behind the boat, you need a conical speaker. Box-shaped tower speakers are also available and can be angled in different directions.

Installation Size

It is crucial that you pay close attention to the dimensions of the available space. There is no standard installation size for recessed marine speakers, but 6.5-inches is common. If you are upgrading, you can use the same mounting locations or existing cut-outs. Keep in mind that even though speakers may have the same diameter, it’s likely that the grille is constructed differently.

Think about where you will run wires, especially if your vessel doesn’t have speaker wiring. Whether or not there is existing wiring, it is important to ensure it is threaded in a concealed manner. This offers protection from the elements.


Another question you should ask yourself is how much power a ​boat speaker can handle. Most manufacturers specify the peak wattage. The root mean square shows the amount of continuous power a speaker can handle, and this is a more important value. If the receiver puts out 100W RMS, you need a speaker with a 100W RMS value per channel at the minimum. Connecting a speaker with 75W peak wattage to such a receiver would be putting it at a risk of damage.

Be sure to consider the output value of your amplifier and choose a speaker that the figures accordingly.

Speaker Quality

Opt for a speaker that is made from long-lasting materials rather than frail ones. The speaker should be able to withstand the surrounding conditions and impact in case it is hit. More protruding designs present a higher risk of breakage and damage due to accidents as compared to less protruding designs.

Resistance to dust, corrosion, UV rays and water is always great. Make sure you get a speaker that doesn’t fade or change color after continued exposure.

Frequency Response

This refers to the range of audible frequencies in the spectrum of human hearing that a speaker can reproduce. It falls between a deep bass of 20 Hz and 20kHz. Good marine speakers offer a broad range of the frequency spectrum, and when it comes to audio, the ideal choice depends on what you will be playing.

Most boat speakers are designed as two way systems, meaning they use different frequency bands. They also utilize a tweeter for the higher end of the spectrum and a woofer for lower frequencies.

Two-way speakers are perfect for most applications like talk radio, pop music, spoken word, and news. Three-way speakers are available, and these use a tweeter, mid-range, and woofer.

Both of the above speakers offer extended functionalities and versatility. If you have a party boat, installing a separate subwoofer is a more efficient way to get the bass pumping.

Speaker Sensitivity

The ability to convert power to sound and create audible waves from energy from the amplifier is called speaker sensitivity. It is specified in decibels (dB), and common theater speaker systems have a rating of 80-84 dB. You can get higher quality models with an average sensitivity of 87 dB. Speakers with lower ratings require more power pumped into them to provide increased volume. While a mid-80s value is standard, a score above 90 is excellent.

Magnetic Shielding

Audio speakers use strong magnets, which can distort and damage sensitive equipment on a boat. This poses a concern when installing speakers close to devices like the boat’s compass. Consider purchasing a speaker with magnetic shielding. This is incorporated in the form of a metal lining. Some manufacturers use a second magnetic that cancels out the magnetic energy.
