Free Air Subwoofers Buyer’s Guide
Below, we will look into recommendations from our sound engineers about what to consider when buying the great free air subwoofers.
Size
As always, you need to be very careful with the size of the subwoofer that you get. A subwoofer with a big size will be much better for playing in outer spaces and large rooms as they most likely have more bass and a broader frequency range. If you’re having a small party or many people over, this is something you want to consider.
But, if it’s a pretty intimate event or car audio, you can go for a smaller sub instead. In general, there’s no one-size-fits-all answer for choosing the best subwoofer when it comes to size. The ideal option will depend on what you want and the situation itself.
Size also matters for placing. Something big might not fit so well in your car trunk, you know.
Power
Measured in Watts, this metric in a subwoofer primarily shows its capacity from an audio perspective. Most small subwoofers don’t have so much power, so you’ll generally see things like a peak strength of 1,000 W to 2,000 W. But, the bigger ones can have peak power ratings as high as 3,000 W and 4,000 W.
On the rarest of occasions, you can see subs go even higher. Of course, a stronger sub can provide more bass on several levels. Whether it’s high bass or low bass, count on it to perform well.
Again, like size, the best subwoofer for you will depend on what you want. Something for car audio doesn’t need so much bass, for instance. But, if you want something for a larger space, you will need a better bass, which means a stronger sub.
Sound Quality
It is beyond important that you pay attention to the sound quality of your free air subwoofer. Subs are a part of your sound setup, and you will need to ensure that they deliver the optimal sound you need.
There aren’t many indicators of sound quality. For most people, testing out the free air subwoofer to see what it sounds like is the best way to handle this metric. But, you can also take note of its frequency and placement. Some subs will need to be properly placed for that crisp audio to come through. Take note of specifications and recommendations from the manufacturer too.
Amplifier
To be fair, it is worth noting that not every subwoofer needs an amplifier. However, the ones with amps tend to be much better when it comes to projecting sound.
If you select a sub with an amplifier, you need to know about the amp and its capabilities. An amp that is strong enough will effectively project the sound to the level that you would like.
So, just remember that not every sub has an amp. If you find that an option you want has an amp, you must ensure that the amp can project good sound.
Frequency Range
Every sub should have a diverse frequency range, making it much easier to control the different elements of a mix. Most people have an audible frequency spectrum of between 20 Hz and 20 kHz.
For subwoofers, there are different ranges. These include sub-bass (20 Hz to 60 Hz), bass (61 Hz to 250 Hz), mid-level (251 Hz to 500 Hz), midrange (500 Hz to 2 kHz), high mids (2 kHz to 6 kHz), and highs (6 kHz to 20 kHz).
Depending on the sound you’ll be looking to project, you can check out the frequency range of the subwoofer to know if it will be great for you.
Impedance
The impedance of a subwoofer is the resisting property of its voice coils. It is measured in ohms [1]. When a subwoofer has a lower impedance, it will be easier for an amp to supply energy. When a subwoofer has a lower impedance, it will be easier for an amp to supply energy.
When the amp’s output hits a sub with a low impedance, you have a problem. The sub will try to supply more energy than it can produce, starting to overheat. If your sub is designed to cut out, then it will shut down when it overheats. If it’s not, it could get damaged.
So, as you check the sub’s impedance, make sure to check its energy as well – if it has one.
Material and Durability
On final thoughts, you also need to ensure that your free air subwoofer is durable. This is a function of the material used in building and designing it. For a lot of people, subwoofers will need to be used outdoors and at gatherings. You need something that can stand some pretty rough environments and still hold its own.
In some cases, the material of the subwoofer can also determine how well its sound quality and bass show. When the sub is properly built, the bass sounds punchier and more gripping. Remember that bass is a finicky sound, so you want something with a strong build if you’ll get the best bass.
Some products also have a rubber surround, which can help with sound amplification. The rubber surround is a great addition, so feel free to check out a rubber surround in the material section.
But, the most important thing here is to ensure that your subwoofer is strong and durable enough to be used in some extreme conditions.
Benefits of a Free Air Subwoofer
As explained earlier, a free air subwoofer is a type of subwoofer that doesn’t come enclosed in a box. Some of its benefits include:
Space-Saving
Since they don’t come in boxes, the best subwoofer options can help you save space. You can easily mount them anywhere, and you don’t need to worry about space consumption. You can even install several of them in your car.
With their air setup, they are not sealed, so they save a lot of space. This is especially great if you want to put one in your car trunk.
Cost-Effective
An excellent free air sub is generally less costly than any of the enclosed subwoofers. This is because they function without an enclosure. So, if you’re working on a tight budget, free air subs will be what you need. They are great for anything – a room, a car, etc.
Low Power Consumption
A free air sub works in an open environment. So, it can easily move air – unlike an enclosed sub. Thus, free air subs demand less output from the amp than an enclosed subwoofer. This is especially true for those with impressive power handling. When power handling is optimal, consumption will reduce. So, check the Watts RMS power rating, overall power rating, and handling metrics.
This is also important if you’re using the sub in your car trunk.
Installing a Free Air Subwoofer
Generally, the processes involved in installing free air subwoofers in your car will vary. Free air subwoofers have different manufacturers, so the installation procedures can’t exactly be the same thing. Also, since many of them come with different features, you will need to install them differently.
One of the most important tips for you will ensure that the subwoofer you select has a simple installation process. Be sure to read the instruction manual thoroughly before you proceed so you don’t make any errors.
Some manufacturers will also offer installation help for some qualifying purchases. Names like Kicker and more fall into this category. Check to see if you qualify for that.
Difference from Infinite Battle
Some consider the infinite battle to be the best for a sound system in your car. These subwoofers have a smooth roll-off when they play low frequencies. They don’t have enclosures either.
Infinite battle systems use large, sealed spaces. But, infinite battle subs are mounted similarly to free air subwoofers. So, they share similarities with installation and other metrics.
However, infinite battle systems take more time and effort with installation as their waves might interfere with each other. With free air subs, you don’t need to struggle with technical complexities that much. So, even an 8-inch free air subwoofer will allow you to make an exceptional sound while not stressing over sealing enclosures.
