15in Subwoofer Buying Guide

15in Subwoofer Buying Guide

As you likely already know, the sheer number of subwoofers on the market can make the selection process incredibly difficult. This is further complicated, when you have no idea what to look for. What factors are important? What should I choose to get the loudest thump with little to no distortion? It is vital to familiarize yourself with the basics before attempting to evaluate each specific speaker. Below, you’ll find a breakdown of the factors that will prove to be most important when investing in a 15-inch car subwoofer.

Understanding The Different Types

First and foremost, you should realize that there are various types of subwoofers. Each has its own unique set of pros and cons. Therefore, you will need to learn about the different types, so you can determine which one is right for you.

Component Subwoofers –The component sub is the most basic. It is nothing more than an automobile speaker. You’ll need to invest in your own power source and enclosure. This is a good thing because it provides you with additional flexibility. You can pick and choose while configuring your own unique audio system.

Component varieties are available in a wide range of different sizes. Simultaneously, you’ll be able to select the amplifier that you prefer best. Component subs might not be ideal for those new to speakers. If you do no select the right amplifier and power source, you may not get the desired audio quality that you’re after.

Enclosed Subwoofers –As the name suggests, this type of sub comes with the enclosure. The enclosed subwoofer might be a little costlier in the beginning, but it is definitely far more convenient. You will not have to worry about finding the right enclosure since the manufacturer has already done this for you.

However, you will still need to choose the right amplifier. Make sure you put in a lot of effort to perfectly match your subwoofer with the rest of your audio equipment. You’ll need a little tech know-how to pull it off.

Powered Subwoofers – If you want to avoid the hassle, you’ll want to invest in a powered subwoofer. With this variety, you will receive a car speaker and amplified. Both will already be mounted inside of a prefabricated enclosure. This completely takes the guesswork out of it.

Powered subwoofers are truly the most convenient and they require little to no technical know-how. Plus, they’re fairly compact and can be installed in almost any automobile. Unfortunately, the powered subwoofer will remove the user’s freedom of choice from the equation.

Again, each specific type is great. In fact, you cannot go wrong, as long as you choose a model that works best for you.


Whether you’re a millionaire or working on a limited budget, pricing will play a vital role in your decision. Pricing is very important for a wide variety of reasons. First, it should come as no surprise to learn that more expensive subwoofers will typically deliver better sound quality and additional longevity. Simultaneously, paying a little more will generally get you a longer warranty. This could make a world of difference in the near future. Nevertheless, it is vital to be realistic with yourself.

It is in your best interest to avoid overdoing it. If you spend too much, you may wind up in financial trouble. Set a spending limit for your audio system and move forward from there. Spending a little more is always recommended, but not always a requirement.

RMS Power And Peak Power

15 inch subwoofers

Now, it is time to delve into the technical aspects of subwoofers and speakers in general. When looking at the speaker’s specifications, you will discover two power ratings. One will be an RMS rating and the other will be a peak power rating. They’re surprisingly very different. Both are important, but any audio expert will tell you that the RMS power rating is even more so. The peak power is the quantity of power that the speaker can handle at once. The RMS power is the continuous maximum power that the speaker can tolerate.

When looking at these ratings, you should follow the simple rule that it is best to have too much power than too little.

Frequency Range

The frequency range is fairly important, but the differences between one speaker to the next are normally minute. This range will tell you how low of a sound the speaker can reproduce. However, it is vital to remember that the speaker’s rating will not tell the entire story. When it comes to 15-inch speakers, there are many other factors that can impact the speaker’s overall frequency range. One of the most impactful is the enclosure. While the range is important, you should not consider it to be a make or break factor.


Sensitivity is important because it tells you how well the subwoofer will be able to reproduce low-frequency sounds. Simultaneously, it is pertinent to closely match the sensitivity with your audio system’s power. If you opt for a speaker with a higher sensitivity rating, you’ll need less power. If the sensitivity rating is lower, the power will need to be increased in order to reproduce the same sound.

Voice Coils

When it comes to subwoofers, most will include only one voice coil. However, there are a few specific models that do have two voice coils. For beginners, the number of voice coils probably won’t make much of a difference. If you know a lot about speakers and stereo systems, you’ll probably prefer two voice coils, since this will provide you with more wiring flexibility.

Overall Size

15 inches is a pretty good size for subwoofers. Nevertheless, you should realize that the size of the subwoofer will greatly impact its performance. It should be fairly obvious that bigger subwoofers will produce a louder sound than smaller alternatives. Of course, size isn’t the only factor that will help to determine the speaker’s overall volume capabilities. The design and enclosure can also play a role here.


For beginners, the impedance rating won’t be a big deal. Almost all subwoofers on the market will have a rating of 4 ohms. From time to time, you will come across 2 ohms or 8 ohms, but this is fairly rare. As long as you stick with 4 ohms, you will not notice a difference. However, it is important to make sure that your subwoofer’s impedance matches the impedance rating of your car’s amplifier.


The technical aspects of the speaker are undeniably important. Nevertheless, you should never ignore the basics. When purchasing any new electronic product, you should carefully investigate the manufacturer. This can tell you a great deal about the product and will give you a good idea of whether or not the product will be worth your time and money. Simultaneously, the manufacturer will help to determine the quality of customer service that you’ll receive.


When purchasing electronics or speakers, a warranty is always vital. Anything can go wrong and electronic devices are always prone to problems. With this in mind, it is in your best interest to get the longest warranty you can find.
