Our comprehensive installation guide includes information for tools needed as well as how-to steps before beginning work with one of these projects.

Meet the Winners!

If you are looking to save space in your boat while still getting a great sounding speaker set, then dual cone speakers might be for you. They can help cut down on weight and cost which is why many people prefer them over coaxial ones. The Sony XSMP1611 6-inch Dual Cone Marine Speakers provide excellent sound quality at under $50 making it an affordable purchase as well!

The Polk Audio DB691 are the best marine speakers for those looking to have high-quality sound and plenty of volume. Not only do they come with a good bass response, but these powerful Marine Speakers can pump out some serious noise too!

This speaker might sound like a steal at just over $20, but don’t let the low price fool you. The Pyle PLMR60 Dual 6.5” Waterproof Marine Speakers are capable of producing high-quality audio for an affordable price making them attractive to consumers on a budget and casual listeners alike!

The Polk Audio DXi651 are the best marine speakers available. Their waterproof woofers and durable rubber surrounds will help prevent moisture, heat, or time from damaging your sound quality.

What makes a speaker a marine speaker?

Salt is a very aggressive element. It ruthlessly eats away at any metal or electronics, so it’s important to find speakers that are designed specifically for salt-air environments like boats and sea-facing properties. It’s important to pick the right speaker for this type of environment, otherwise, they will corrode and break within a year due to saltwater exposure that ruins metal and electronics. You want your sound system components (speakers, receiver, and amplifier) to last well into the future so you can enjoy entertainment any time you please!

Marine speakers are designed and manufactured to withstand the corrosive nature of salt water. These waterproof, anti-corrosive components will not only last longer but sound better than a standard speaker. Marine speakers offer more durability in addition to quality audio output that is resistant to corrosion due to their design which includes corrosion-resistant materials like stainless steel fasteners or marine plastics for internal parts such as cases, gaskets, and wiring insulation

Can I use marine speakers for my patio?

Yes! There are several reasons to choose marine speakers for your outdoor home audio system. As we mentioned, marine speakers are not only water-resistant but also provide protection against corrosion. This makes them ideal for use outside your home, particularly in areas close to the sea or in a humid area like Florida.

Dual-Cone vs Coaxial Marine Speakers

One of the biggest considerations when it comes to choosing marine speakers is whether they will be mounted on a boat’s deck or hull. The two types you can choose from are coaxial and dual-cone models, so let’s take a look at what sets them apart.

Dual-Cone Marine Speakers

A dual cone marine speaker is a type of loudspeaker that combines the woofer and tweeter into one driver. The biggest advantage to this design is cost, as there are fewer parts required for production. However, without audio separation between the two drivers on a single plane, it doesn’t function quite as well in comparison with coaxial designs where each unit has its own housing space.

Coaxial Marine Speakers

Coaxial speakers are the most common form of loudspeaker available in both 2-way and 3-way setups. The design is such that the tweeter is mounted in the center of the woofer, partially obscuring it. Both drivers, either internal or external crossovers send separate audio signals to each other for a crisp sound while using less space than traditional stereo systems would require.

Our Selection of the 10 Best Marine Speakers

A common question sailors ask is “what is the best marine speaker?” With so many different options to choose from and no way to know which ones will work well on their boats, it can be hard to find something that sounds good while being accessible in price. Lucky for all of us who want great sound without breaking our budgets or doing too much heavy lifting (or maybe some light reading) – we’ve compiled not just one but ten awesome choices!

With a choice between four different sizes, we went with their most popular option – the Polk Audio DXi651 marine speaker.

Amplification Recommendation

The PLMR60 provides a reasonable power handling of 75W RMS to 150 W Peak per speaker, which can be easily driven by your standard marine receiver, such as the Pyle PLMRB29 In-Dash AM/FM Receiver.

If you want more control over the sound and are looking for an amplifier that’ll work with any controller or receiver then we recommend Pyle’s Hydra Marine 800 Watt Amplifier. It will give you all the features needed in order to achieve optimal performance from these speakers whether it is powering them off your own system or as part of another larger setup like houseboat audio systems!

Speaker Installation

The PLMR60’s plug-and-play wiring and mounting hardware make it easy to install, even for those with more demanding installation needs.

You have two additional channels left over to amplify other marine or subwoofer systems in case they are needed down the line!

Speaker Quality & Design

The DB521 has a 5¼” low-frequency driver with a single ¾” tweeter. The sound quality is good for the size, however, bass response isn’t as good as larger options we reviewed in this article.

How to Install Marine Speakers

Installing marine speakers can be a daunting task, but with the proper preparation and planning it is possible. When installing your system you need to make sure that they are protected against rust or corrosion found in saltwater and sea-air. Installs should always include materials such as silicon sealant for protection from moisture seeping into joints between panels or seams of metal sheeting where wiring passes through holes in deck plates (this may also necessitate more frequent maintenance). You’ll want to take this process one step at a time so paying attention while going through your installation will help avoid any problems later on down the line!

Step 1:

Attach your speaker template to the chosen position. Cut a hole for your speaker position and drill the holes for each of the mounting screws.

Step 2:

Place the foam gasket to the back of your speaker and align with its hole. This is a necessary accessory that will make it easier for you to fit your wire through when attaching it in place, so don’t forget!

Step 3:

Connect the speaker wires to each terminal making sure positive and negative are connected properly, then tighten down with a screwdriver.

Step 4:

Slide the speaker in place and secure it with screws. Give all of the screws an anti-rust spray so that your speakers will be safe from corrosion.

Things to Consider before Purchasing Marine Speakers

If you’re looking for marine speakers, there are many features to consider before making a purchase. Here are a few of the top features to consider before buying marine speakers.

Type of Boating Activity

The most obvious and often overlooked first point is what you wish to use the speakers for. Some people purchase marine speakers so that they can enjoy their music on a boat while fishing but other types of activities require different levels of volume in order to be enjoyable. If you plan on doing things like wakeboarding or waterskiing with your new setup, then louder volumes are necessary because these sports involve being farther away from the speaker than when simply sitting near it during an afternoon cruise around the bay.

The type of activity will influence how much power your system needs. Generally speaking, those undertaking more strenuous physical exertions need higher wattage systems whereas those who would just want something low-key can go for a marine speaker with average power.

Marine Speaker Types

When choosing speakers for your boat, you have three options that all depend on where the speaker is going to be installed. Your options include flush-mount speakers, enclosed speakers, or wake tower speakers. It’s important that they are installed in a location conducive to their size and purpose so as not to compromise performance.

Flush Mount Marine Speakers

The flush mount marine speaker is the most common type of speaker found in motor vehicles and is commonly mounted on boats. They can be installed anywhere inside or outside a boat, so they don’t take up any space at all!

Enclosed Marine Speaker

An enclosed speaker is a speaker that’s designed to stay inside of its enclosure. These speakers are often used in bookshelf speakers, PA systems, and soundbars because they have more space for them than on boats that lack the necessary room. The benefit of mounting an enclosed loudspeaker over a flush mount marine one is their increased fidelity as well as the ability to be mounted higher up or angled towards certain areas with improved audio quality.

Waketower Marine Speakers

Waketower speakers are perfect for people who have a bar or tower to mount the speaker on. These directional, high-powered speakers can project sound up and are great if you want more volume. Waketower marine speakers don’t offer a phenomenal bass response, but they can be very loud! 

Speaker Positioning

The next decision you make in your boat speakers installation will be the location of where to install them. You can either replace factory-installed speakers that are not performing as well as they used to or if there is a frequency range missing, then more sound at different places on the front and backside would do better for when you’re trying to get into waves with someone else close by who also has music playing loudly from their speaker system.

Most speakers are directional, meaning they can only send music waves in the direction that they’re pointing. Make sure when purchasing new speakers that it is pointed towards this area for full coverage.

When it comes to marine stereo, you must consider the right balance. It is important for your music to come from both sides of the boat; this way sound can be heard throughout and no matter where someone sits or stands aboard they will still have an enjoyable experience listening in on what’s going on. This is why speakers are installed all around so that there isn’t any imbalance with their placement – achieving a balanced system ensures everyone has access at any time!

Magnetic Shielding

In your quest for the perfect sound system, you need to consider how magnetic devices may affect it. A compass will be distorted if a magnet is too close and this can create problems when navigating using that device as well. The magnets on speakers aren’t usually strong enough to cause issues but especially with marine speakers mounted in consoles near compasses; they should come equipped with shielding or check first before mounting them there.

Your Budget

Deciding which speakers to buy for your boat can be a tough decision. On the one hand, you could go into a store and pick out some of the most expensive ones in order to get what you think is best; but these may not necessarily match up with what’s actually needed for use onboard. You should always consider all available options and select one based off of what will best suit your needs; even if money seems like it doesn’t matter at first glance!

Replacing your Factory Speakers

After years of listening to your car’s factory speakers, you may be ready for a change. This is not always as simple as it sounds! Different speaker sizes have different depth and screw mounts which can make the replacement process difficult. To eliminate these potential headaches, measure your old speakers first so that when you go looking for new ones, they’ll fit exactly where needed with nothing extra leftover – just connect and tighten them in place securely before sealing up all holes around the perimeter using silicon or 100% silicone sealant.

Marine Speakers Technical Information

Understanding Power Handling

Power handling is like a speaker’s stamina. Speakers have two power ratings, RMS and Peak wattage.  The RMS wattage indicates the lowest level at which a speaker can play while still projecting an audible sound, whereas peak wattage refers to the maximum power that the speaker operates at.

Understanding Amplification

In order to find the right amplifier for your marine speakers, you’ll want to select one that’s between 1.6 x – 4 x more than your speaker’s RMS power handling. If the amplifier doesn’t have a limiter, then you’ll need to match the RMS wattage of the marine speaker with an equal RMS output from an amplifier.

Additionally, you’ll also need to consider speaker impedance when selecting the right amplifier. When an amplifier is powerful enough to power a speaker, it’ll have specifications for the type of impedance that needs to be matched. An example would be 100W 8-ohm speakers which are made for amplifiers with this same wattage and impedance specification.

It’s important not only to match these numbers but also to ensure they’re adequately sized in order to avoid blowing them out or damaging your equipment over time due to clipping and peaks as well. Marine speakers typically operate on 2 or 4 ohms.

Knowing Which Cable Gauge to Use

Knowing which speaker wire gauge to use can seem confusing at first but it’s actually pretty simple with some basic knowledge. In order to select the right cable gauge, you need to consider the length of the cable as well as the speaker’s impedance.

Make sure both left and right speaker channels are identical in length, with as little slack as possible at either end. Avoid coils or large loops in excess length because this generates heat. For longer wire lengths, make sure you step up in gauge size for optimum sound quality!

Most manufacturers will recommend using either a 16-gauge or 14-gauge speaker cable for marine speaker installations. We’ve included a chart below to help you calculate the correct gauge based on the impedance of the speaker and the length of the cable. Each value is the maximum length and we’ve capped lengths at 50 feet, as lengths longer than this are generally not recommended.

Waterproof Rating

Marine speakers are built to be as durable and resilient as you need them to be. From waterproofing for the long haul, corrosion-resistant materials that can take anything from saltwater waves crashing against your boat’s sides or salty air onshore, marine speaker manufacturers have got it all covered with their products. Not all waterproof ratings are the same though, with IPX ratings ranging from just water-resistant to fully waterproof. Be sure that the marine speaker you’re looking to buy matches the right level of waterproof rating needed for your needs.
