The Boss audio system has remained dominant in the sound and speaker world for a while now. If there is a product offered by this manufacturer, you could be sure that you will be investing your money on the right thing.

Since Boss believes and has full confidence in what it is selling, it provides 3 years platinum dealer warranty. They are very easy to install.

What to Look For in Best Marine Speakers

Choosing marine speakers could be a little confusing. Therefore, in this section of the article, I will break down everything you need to know about picking the right ones.

Installation Size

When you are planning to replace the speakers, the first rule to keep in mind is that there are no replacement sizes. Even if it seems like they are, believe me, they aren’t. The diameter provided or published by the manufacturer is usually the diameter of the cone inside, but at the same time, that does not guarantee the grille’s diameter or the cutout hole’s diameter. Moreover, each manufacturer has a different installation size. This actually makes the process of finding replacement marine speakers very painful. However, you can use the cone size to get you into the ballpark, but you must pay attention to all the measurements to make sure that the speakers you are considering are a perfect fit. 

Adequate Space

In addition to the cone sizes and all the installation process has its own set of challenges. Larger speakers tend to have a better frequency response, so it is a good idea if you try to fit in a speaker of the same size as possible. Keep in mind that a speaker will have grilles larger than the cone, so make sure you have adequate space available. 

Adequate Depth

Another issue with marine speakers is the need for adequate mounting depth. It is imperative that before choosing to buy a particular set of speakers that you take a look at the mounting depth of the speakers. There should be enough space available to accommodate both the magnet and cone. If it is the case, otherwise, there is not a whole lot that you will be able to do about it.


Amongst all important things that should be considered before buying marine box speakers, resonance cannot be ignored or overlooked. There should be enclosed airspace behind the speakers to maximize the resonance. If there are speakers that have magnets hanging out in open air will sound weak and tinny. You will not need a full enclosure for that, but something for sure that covers the backside properly. Considering your size limitation, it will become easy for you to narrow down your options and move onto the next criteria for making your decision.

Power Handling

Power handling is a major factor when it comes to deciding the perfect pair of marine speakers. You would want your speakers to be able to handle more or an equal amount of power than your amplifier or stereo could provide. This way, you will be preventing blowouts. The way manufacturers sometimes go on about publishing and measuring power can sometimes become confusing. Therefore, high-end speaker manufacturers usually provide both wattage types and numbers because these numbers are crucial when you are using your speakers with an external amplifier.

Speaker Quality

Now comes the most important part, i.e., the quality of the speaker. After you have read through and understood about the power handling and size of the marine speakers required for your setup, the last thing you would want to carefully consider is the speaker quality. The following are popular types to consider:

Dual Cone

Using only two cones and one speaker, the dual cone speakers happen to generally be the least expensive and also of the lowest quality. These are budget-friendly speakers and are good enough for someone who just wants to make things work and is not extra conscious about the sound quality and all. The smaller cone is responsible for making sure that the speaker is reproducing higher frequencies. In contrast, the larger cone makes sure that there are bass and midrange. They will work OK, and you shall be able to find good quality dual cone marine speakers since they are readily available in the market.


Often termed as 2 way or 3-way speakers, coaxial speakers are the next step in the speaker world. The term “coaxial” comes from the fact that one speaker is wrapped around another. Typically, you will have a tweeter that is installed in the woofer’s middle cone with a driver that is completely separate. The speakers then divide the frequencies by using a device called a passive crossover. However, one limitation to these speakers is that since one speaker is wrapped around another, the vibration produced can interfere with each other creating cross-phase distortion.


Component speakers are more expensive than both coaxial and dual cone speakers as they are built with a tweeter utterly separate from the woofer cone. Thus resulting in successfully eliminating cross-phase distortion. Since they are also made of better quality materials, one could imagine where the price hike comes from.


The subwoofer is basically an additional speaker being added to your already existing sound system to handle the lower frequencies better. Subwoofers are a sure way to enhance the sound quality of your music system. Moreover, subwoofers require sufficient power to give that thump to the music you have always wished for, but that would only be possible if you have an amplifier. A Stereo head unit will not be able to provide enough power. So, if you are not able to give your subwoofer enough power, you might as well not use it because you will not be able to feel any difference either. 

Additionally, you can fit small marine speakers in your boat and place a subwoofer under the seat. Or put it at any other location that is down low so that it can provide that extra touch to the overall sound system quality.
