10 Best Marine Speakers in 2021

We are diving headfirst in this post, (no pun intended) for a look at the 10 best marine speakers in 2020. The market for audio-electronics is practically full of competing goods, which can often make it even harder to differentiate between the good and the poor.

Some marine speakers are more waterproof than others, as dumb as it sounds, moisture resistance is measured in varying degrees, so some items we will look at today may be fine mounted within a sheltered boat cabin, but against mother nature mounted on a mast in a monsoon will not do too well.

View The Best Marine Speakers Below

1. Rockville RWB80B

In our posts, we discuss stacks of speaker choices and we are no strangers to a rocking set of Rockville's. In terms of bass reaction, they produce some of the biggest models on the current market, so it is unsurprising that their meaty 2-way marine alternative provides some low power handling. They are intended as models of wake-board towers and are easily mounted on bars and roll cages. They are suitable for a variety of vehicles, but the long steps taken by Rockville to shield these bad-boys from the battering salty sea air make them a better choice for a marine mount.

They are completely protected against salt and freshwater conditions, with rubber gaskets sealing all terminals. They are to a high degree waterproof and totally resistant to rust.

The woofers measure 8 inches and feature a cone of high-grade polypropylene that has been injected with mica. In order to help dampen unwanted resonance that can cause bass distortion, it handles extremely well and is based in a Santoprene setting.
It is coupled with a hard-working mid-range 1-inch dedicated tweeter shaped with a rigid composite dome of polymide. Thanks to the excellent on-board crossover circuitry, it houses a high-density neodymium magnet and comfortably copes with the assigned upper frequencies.

They have 300 watts (200 RMS) of high peak power handling, sound intensity levels of about 98 decibels, high frequency response and low impedance.


  • + Waterproofed to withstand marine environments outdoors.
  • + High production.
  • + Simple installation.

Why We Liked It:These guys had a lot of poor reviews, aren't we sure why? In general, Rockville speakers are fairly darn sturdy, and with a high performance they handle impeccably under strain, this pair is a testament to their top notch engineering.

2. Kenwood KFC-1653MRW

Sector granddaddies Kenwood, a business with plenty of experience under their belts to see what seaworthy sets they serve, over to another of the best brands in speaker production. They are of a 2-way classification, like the Rockville option reviewed above, and although the bass on a Kenwood speaker appears to be more understated than a Rockville, they produce very rich, well-balanced audio.

They are a more lightweight and much less efficient pair in direct contrast, but actually ring-up at about half the cost, offering some great value for money. They are often offered in pairs and their 2-way array consists of a mixture of woofer and tweeter to effectively sort the workload for maximum output from the peaks and lows to the right driver.

"The woofer is 6.5" and the balanced dome tweeter is made of a water-resistant polypropylene composite, just under an inch and again made of materials that can withstand the weathering to which a weak speaker can be subjected by marine life.

Thanks to advanced crossover circuitry improvements Kenwood has introduced, the drivers make a reasonably large frequency response and share their duties harmoniously.


  • + Dedicated tweeter and woofer
  • + materials immune to water.
  • + Priced affordably.

Why We Liked It:They actually generate full-range natural sounding audio representation, the crossover is seamless, and we love affordable pricing. Definitely a safer alternative than the normal risky option of a boombox for your cruise.

3. Kicker White OEM

Now for a look at what Kicker has on offer in the department of maritime readiness. You'll know that we have a soft spot for coaxial rivals from Kickers if you have read any of our other speaker reviews.

First of all, these babies come as a package of 4 now and if you're very serious about pimping your deck out a bulk order is worth its weight in gold.

They benefit from the same blood, sweat and tears that Kickers' other best-selling model put into studying optimum driver efficiency and configuration. In addition, and most importantly, many of the components have been optimised and redesigned for as long as specifications are required to deal with life at sea. No joke, they were expertly made using only parts that are waterproof, rust resistant and UV treated. They feature sealed engines, stainless steel mounts and terminal covers for locking, and actually exceed some of the water-resistant speaker industry requirements.

The weatherproof woofer, like the Rockville's, is 6.5 inches and injection-molded from Santoprene. While the tiny 13mm dome tweeter is porcelain/enamel treated (PEI rated) and defines the crisp and crystal peaks, the lower frequencies are closely controlled. For a 2-way class set, they have a reasonable frequency response.


  • + Audio drivers for the maximum set.
  • + UV treated and materials resistant to water/rust.
  • + Four-pack

Why We Liked It -:-They serve the same notorious killer Kicker sound in a waterproof package that is full-range with depth and definition, with some high-end dimensions that exceed some speakers specially designed by maritime producers.

4. Sony 4 XS-MP1611

This stylish Sony package of four marine speakers provides your boat with an awesome upgrade. They contain dual cones and are 6.5 inches in height. The dual drivers work surprisingly and cope with a reasonable feedback. They have RMS power of 65 watts, 130 per 4-pack and 140 watts of full power (280 watts per 4-pack).

They are lightweight but very robust with quality materials, all housed in an IPX5 rated enclosure that makes them adequately waterproof for marine use (UV-ray and salt-waterproof).

The crossover capably deals with the frequency response and workload balance, delivering great sounding audio. They have rustproof, low impedance circuitry that has been perfected in their field by their years of experience. They are easy to mount (can be mounted front or rear) and need only a 4-15/16 inch cutout and few regular spade wires. They come in a standard black or white style and have adjustable grilles.


  • + Impedance poor.
  • + Four-pack.
  • + Dual Taper.
  • + Waterproofing by IPX5.

Why We Liked It :We are a little dismayed with the plastic waterproof grille, but the low price tag, has to come with some compromises, fortunately the sound quality is not something Sony wanted to understand. They make for another great sounding bulk buy choice and come from a trusted brand.

5. Kicker 11 KB6000W

Now for another look, in the form of a mini-box speaker option, at Kickers aquatic battle audio solutions. They are a rugged rigging pair, perfect for mounting as well as stowing away below deck in the sea breeze.

They are another 2-way classified device with a reasonable price that has dual drivers met with great crossover circuits to provide an accurate frequency response. They perform very well and delegate the workload between the dedicated woofer and tweeter combination effortlessly. With a peak of 150 watts, they have excellent power handling at high performance (75 watts RMS each).

They are simple to mount and come with all the necessary mounting components. Each component is designed with durability in mind, has coated circuitry to prevent rusting, and is UV-treated. In a water-resistant enclosure, all the carefully sourced components have been sealed, making it properly prepared for any outdoor use.


  • + 2-way array of groups.
  • + Concept Block/box.
  • Power control of + 150 watts.
  • + Price affordable.

Why We Liked It :They are a well-designed pair of IPX 5 certified enclosures, so they are suitable for on-board mounting.

6. JBL MS6520 180W

This moderately priced pair for JBL might be a good low-profile choice for your interior vessels. They feature the primary ingredients for some of their other best-selling speakers with their proprietary Plus One woofers. The ingenious Plus One technology helps to optimise the surface of the woofer cones, a design principle that improves reaction and performance.

The woofer is coupled to a balanced dome tweeter to cover a large spectrum of frequencies, with cooling in place, the tweeter deals extremely well with high energy. They provide audio with real depth and clarity together.

They have drivers that are independently voiced and built to combat the elements. As a dampening measure, they feature waterproof motor frameworks and a one-piece cast polymer basket, sealed magnets and rubber surrounds.


  • + One Tech Plus.
  • + Materials of good quality.
  • + Wonderful value for money.

Why We Liked It :- A remarkably strong pair with unprecedented dispersion, the Plus One technology is a perfect addition to any speaker system's woofers.

7. Polk Audio Atrium


If you like the Kicker KB6000s mini-box design theme, then these sleek fellers from the Polks outdoor Atrium series are well worth a look. They are an outstanding pair who, when they first appeared on the market back in 2002, lifted the industry standard bar. Their formula for wider open-space coverage and tough environmental endurance actually meant that military specification models surpassed their performance capabilities.

Their power handling and frequency response are designed for the elements to be highly tolerant and robust. For deadening unwanted vibrations, the tweeter domes are made of anodized aluminium and feature a rubber surround. Without losing the meaning and clarity, the baffles are built to disperse the sound more efficiently in a large region.

They are installed in an extremely simple way, by means of a speed-lock system for quick, secure installation under severe weather conditions, requiring only one hand to be used.


  • + Rugged assembly.
  • + military grade components treated.
  • + Wide dispersal outdoors.
  • + Simple lock for pace, one-handed mounting.

Why We Liked It:These are a heavy-duty collection of speakers outdoors that really mean business. They are ideal for marine mounting due to the design protocols in place to protect against extreme weather.

8. Kenwood KFC-2053MRW

For another excellent sea-sailing speaker range, back to the audio titans at Kenwood. This package provides a slightly larger woofer (at 8 inches) and a slightly lower price tag in direct contrast to the first Kenwood pair we tested, and the sound is really astounding for a bargain 2-way class speaker. Without distortion or breaking up, the volume levels can be increased, filling even the largest cabins.
They also have a meatier max wattage totaling about 300 watts than the KFC-1653MRW model, so these little guys are deceptively heavy.

The dual drivers working for and for each other are well balanced. Thanks to the 1" balanced dome tweeter that performs exceptionally well the lows are pleasantly surprising and the highs are crisp and high def."

They are painstakingly built to carry specialist Kenwoods audio skills to waterproof depths. The motors are perfectly sealed for maximum safety against the elements and all materials are treated to be moisture resistant.


  • + Superbly produced.
  • + Low-cost.
  • + High production.

Why We Liked It:They are a well-designed, thoroughly thought-out pair, have nearly flawless circuitry, and are very user-friendly for fast and easy installation.

9. Kicker 41KM654CW

In the form of another robust, 2-way class coaxial package of 4 speakers, time for another gander at Kickers marine speaker options. Together with a peak RMS of 65 watts per speaker totaling 360 watts, they handle high forces.

They have a water-resistant, heavy-duty build that is made of high-quality materials. To withstand exposure to moisture, each part has been treated. They have a waterproof 3/4" titanium dome tweeter, the surroundings are composites of rubber of marine grade and the engine is fully encased."

They are relatively easy to mount and deliver an impressively loud, well-balanced cabin-filling sound that has large dynamics, nuances and crisp details.


  • + four-pack.
  • + immune to water.
  • + High production.
  • + Complex sound, matched with great clarity.
  • + Unpaid value for money.

Why We Liked It :This make for the most impressive upgrade to stock speakers if you have a good amplifier and aren't too concerned with power consumption. Despite their low price, they are very high quality, practically offering the most bang for your buck.

10. Magnadyne WR40W

This wonderful Magnadyne marine set certainly makes some waves in the midst of an armada of pretty poorly performing low-cost choices. They are very well-designed and incredibly affordable, outperforming most of the lower price regions. Their unexpected success is rather unbeatable, at about 25 bucks for a pair.

They have been advertised as OEM hot-tub speakers for outdoor and marine applications, but they work enormously well.

They feature a dual cone design that effectively maximises the compact space and simultaneously achieves the widest possible frequency response. They are low wattage, meaning they're not going to demand too much power from your vessels. For each speaker, the maximum power control is 25 watts, but they still manage to pack a pretty impressive punch.

All electrical components are encased and have permanently attached integrated grills, which are moisture, heat, cold and shock proof. For all OE tubs, they are easy to instal and precise substitutes


  • + Configuring dual cones.
  • + Option for low performance.
  • + Highly immune.
  • + Today's cheapest product ratings.

Why We Liked It :They are a very cheap choice that still performs well, ideal without a lot of options for those on a budget, the volumes are not as spectacular as others, but they are quite amazing value for money for the price.

Marine Speakers Buying Guide

What to look for in Marine Speakers?

To say that it might seem completely redundant, but water resistance is paramount. There are models that masquerade as capable of navigation, so you need to know what to expect in a suitable marine package as usual. It is necessary to house all electronics in an airtight/water-tight sealed unit. Metals that do not rust or are to be treated to prevent/eliminate rust must be all metallic parts (rust-proofing).

In keeping your audio noise-free, the surroundings of a cone are critical, they need to dampen noises that are not audio wave response. Rubbers and other lightweight composites are usually used by businesses, but the sun will easily destroy these materials, so the surroundings should be adequately shielded either by clever grid designs or UV protective treatments.

In general, they don't need to be just as hardy as their external counterparts if they are for your interior mounting, but seeing as the amount of humidity, rising damp and mould can all be the wetter they can manage indoor cabin problems, the better the result is in terms of life expectancy.

A 2-way class system is adequate to manage a sufficiently large frequency response if you want fair audio quality. You would also want to go for something with an extended dispersion for external mounting so that the audio is not lost in the open air.

Of course, and you have to take your power usage into account, normally, it's easier to have relatively lower performance unless you have the increased power potential for anything a little more meatier.

Why do I need Marine Speakers?

You probably don't need a marine collection of speakers if you don't have a yacht, which is said to make them suitable for a variety of other vehicles, such as caravans, camper-vans, and off-road vehicles such as quads that kick up a lot of dust. This is because waterproofing techniques are excellent methods of weatherproofing, and they are usually dust-tight as well as water-tight.

They are also suitable for speakers surrounding the pool, or installations in spas and saunas and other areas where they can get wet.

Are Marine Speakers Waterproof?

Yeah, they are the majority we looked at today are very highly rated. However some of them are what we term water resistant if you have enough cash to part with several versions on the market that are waterproofed so well that they can survive complete immersion in liquid and live to tell the tale. They have to tick several important factors off the list to be deemed sufficient in order to be considered a maritime model.

Both circuit mounting and other metals should be made of material that is rust-resistant, usually stainless steel as it is a relatively inexpensive material.

When we talk about waterproofing, we generally score the item's enclosure by IP, calling it a number that relates to how 'dust-tight' and waterproof the product's housing is. If it is properly dust/airtight, then we consider it safe to damage internal parts from water and other particles getting inside.

The numbers range from 1-7, 1 being no special protection, it then goes through from condensation proof to water droplet proof, then shielded from water spray or low-pressure jets, on to heavy waves, temporary immersion, and finally 7 showing that the object is adequately protected from the adverse effects of prolonged immersion.


It is a much easier job than it once was to find a quality collection of marine speakers, you are no longer expected to find a specialist store The worldwide web has made it much easier to find a fab upgrade. You will ideally want to find replacements that are the same size as the existing speakers for the smoothest installation when pimping out your pontoon, and as stated in our guide, unless you are going for a complete system overhaul with more freedom, you need to consider your power consumption and the capabilities of your amplifier.

Waterproofing is a technical development in which we are nowadays much more experienced, but luckily the items available are much better than they were once. It should be a breeze with the sheer amount of talent on show for top manufacturers to find an outstanding set of speakers for your boat, as long as you know what to look for. Hopefully, our guide of feedback and buyers would have served its purpose in helping you make an informed purchase.

Expert Tip:

If you are a novice renovating an old vessel, if you are completely new to the world of wiring a sound system, many of the speakers we tested today are built with a flagship amplifier in mind. If you are a novice renovating an old vessel, it may be worth looking at some complete systems.
