Are you looking for a free air subwoofer? In this article, we’ll explain exactly what a free air subwoofer is, why you should get one, and how to choose the best one.

So what are you waiting for? Let’s begin the discussion.

What Is A Free Air Subwoofer?

A free air subwoofer is a speaker which is normally part of a full-range audio system. They are typically located in the back of a room or between your speakers. These speakers are designed to produce low frequencies. Most people use them to fill out the lows so that the bass sounds fuller and louder.

It’s something you might want to consider buying as an upgrade from your old subwoofer. If you’ve had your current subwoofer for a while, it could be time for an upgrade.

A free air subwoofer uses the same technology as other woofers, but with some differences. Free air subwoofers are typically more powerful than standard woofers, which means that they produce more bass sound than your average woofer. They’re usually more expensive than traditional woofers, but they do give you more bang for your buck.

Reasons To Buy Free Air Subwoofer:

Following are the major reasons to buy free air subwoofer. So have a look at them and get a reason to buy one.

It’s Less Expensive:

Even if you’ve been using free subwoofers or amplifiers for a while, there are still many great deals and discounts on premium models. By comparison, if you were to purchase a premium model, you’d pay a little over 100 dollars more for the same performance.

You Get Free Updates and Support:

Most of the subwoofers available today come with a warranty. If your subwoofer stops working within the manufacturer’s warranty period, the manufacturer will cover it at no charge. If you don’t need the warranty, you can usually just buy the equipment at a discounted price. Premium subwoofers also come with regular updates and support.

The Quality is Better:

Quality is a big factor in whether a speaker is good or not. The best speakers have a top-notch design, technology, materials, and construction. Some of these speakers are very expensive, so there are a lot of choices out there. If you can afford it, go for it. But even a basic subwoofer will perform well if you’re willing to invest in quality products.

You Don’t Have to Take Time Away from Other Projects:

If you’ve got other projects to work on that need your attention, you don’t have to worry about spending time installing a subwoofer. You can put the time towards other things instead. It’s important to remember that you’ll need to do some setup work as well when setting up a subwoofer.

Your Music Sounds Better:

Your music sounds better if you buy a premium subwoofer. Your speakers are more responsive and crisp because you can pick out the details in your sound. For most people, this is the best reason to get a high-quality subwoofer.

Tips To Buy Free Air Subwoofer:

If you’re thinking of buying a free air subwoofer to use as part of your home audio system. You’ll want to consider all these things before you commit to an investment. This is because, even though they make great music, they are also rather expensive and bulky to transport. Before you purchase an air sub, here are some things you need to think about:

Size and Weight:

First off, the size of your air sub will determine what size you will need to go with. A 3.25" subwoofer has the same amount of surface area as a 4.5" sub but weighs half as much.

You can expect a 10" sub to weigh 1-2 pounds, while a 15" sub can weigh up to 5.5 lbs. While this may not sound like much, keep in mind that many people use a pair of subwoofers in their system, and they may be adding a few pounds to their system - so they could easily tip the scale over the power-to-weight ratio on their amplifier.

In short, you don’t want to be adding extra weight to the system if you have an amp with an overload capacity.

Room Acoustics:

In general, air subs are great at making sounds, but only up to a point. If you have a large room, you may be able to get away with just one subwoofer, but if your room is small, you’ll likely need two or more. If you plan to use your sub in multiple rooms, it’s also important to make sure your speakers aren’t going to hit the walls and ruin the performance of your speakers.


You can either purchase a powered sub, which will run off the power of your amp (most of the time), or you can buy an unpowered sub. A powered sub will make better music, but you’ll probably want to keep the amp that you already own for it. On the other hand, an unpowered sub is a perfect choice if you want to take advantage of the size and weight savings - all you need is a long extension cord. This will allow you to hook up your amp and use it as your sub without being near your speakers.


Another important thing to think about when buying a subwoofer is what type of accessories you plan on using with it.

Sub Amp:

If you plan on using any speaker-level controls (volume/treble/bass controls), you’ll want to have this included. If you’re planning on going with a powered sub, you’ll also want to add a sub amp to power it.

Speaker Cable:

You’ll also want to think about getting a speaker cable for your sub - most powered subs have different inputs and outputs than typical amplifiers.

Sub Cable:

The sub cable is the wire that connects the speaker output of your sub to the amplifier input - the more expensive the cable, the more signal quality you can expect to hear from it.

Sub Amplifier:

You may also consider buying a sub amplifier that will allow you to play multiple frequencies in your system at once. This can be beneficial if you have both a sub and a woofer in your home, allowing you to use one for stereo or surround-sound playback and the other for deep bass response.

Ultimately, the right air subwoofer can be a great addition to your home audio setup. It’s easy to find them online, so there’s no excuse for not having one. But if you want to buy one that gives you value for money, you need to think about all the factors above before you make your decision.

Wrapping It All Up!!!

There are very good reasons why people are still buying air subwoofers. But the fact is that you can’t hear any difference between an expensive and low-cost air subwoofer.

Also, for most of us, they’re just too costly. So we end up spending on headphones instead. But if you can afford them, then they’re an awesome investment that can last many years.
