What is a Subwoofer Box and Why You Should Get One 

A subwoofer box is basically just what the name says: a box or enclosure designed for your car’s subwoofers.   

inside the trunk space.

There are four types of subwoofer boxes that you can choose from: sealed, ported, bandpass, and free-air.  

Sealed  

Sealed enclosures, as the name suggests, use a compact design with a single opening. The design lends itself to versatility as most subwoofers can easily fit inside one, and it fits in nearly every vehicle. However, because it doesn’t push air in and out of the box as much, you’ll need to play your speakers at higher volumes to notice the improvement.  

Ported  

Ported subwoofer boxes result in a more powerful bass sound compared to sealed boxes. They’re also designed for better airflow that helps prevent overheating. This design is best used for those who like to listen to bass-heavy music, like rock, heavy metal, and other kinds of bass-heavy audio.  

Bandpass  

A bandpass subwoofer box is usually a variation of a ported box. It’s usually used for dual subwoofers with one chamber open and the other enclosed. This is a design best for those who know what they’re looking for subwoofers. The sound quality is often described as aggressive and best for hard rock, rap, and reggae.  

Free-Air 

Free-air subwoofer boxes usually use the trunk as the enclosure, with the subwoofer mounted on a board before it is attached against the rear seat. This minimizes the sound distortion commonly associated with subwoofers without boxes. They’re great and easy to install but only work if used with free-air subwoofers.  

Things to Consider When Picking a Loudest Subwoofer Box Design 

There are 4 major factors you should consider when choosing a subwoofer box design: the type of enclosure, size, available space, and aesthetics.  

Type of Enclosure  

Most of the time, sealed boxes are used because they don’t take up as much space, and they are fairly cheap. However, if you have more space available, you can enjoy better-quality music using a ported box. Meanwhile, bandpass boxes and free-air boxes are best used for subwoofers specifically designed for such purposes.  

Size  

The size of the box is determined by the type of enclosure used, how many subwoofers you want to fit, and the size of your speakers. The closer the size of the subwoofers you’re using is to the size of the box design, the better, or else you will need to modify your enclosure. 

For a powerful subwoofer, you should look for subwoofer drivers that are eight inches or larger. These subwoofers take up extra space, but they will enable distortion-free sound on flat frequency response.  

Available Space  

How much available space there is on your vehicle will also determine what kind of subwoofer box you’re allowed to use and install.  

Aesthetics 

Most manufacturers make subwoofer boxes with carpeted exteriors or slanted designs to help improve their look and make them fit better with the rest of your vehicle’s interiors. Consider the available space in your car before you choose the enclosure design so you can create a seamless look that best suits your vehicle’s interior.

Frequently Asked Questions

If you are redoing your vehicle’s audio system for the first time, you will likely have plenty of questions. Here is a quick look at some of the most frequently asked questions regarding subwoofer enclosures. 

Can I Add Different Subwoofer Sizes to One Box?

It is not a good idea to add subwoofers with different dimensions to the same box. This may cause distortions and can increase vibrations which may damage the subwoofers. It’s best to find a box that is compatible with your subwoofer size.

Does a Bigger Box Make Subwoofers Louder?

A larger subwoofer enclosure can increase the bass level a bit but the sound will usually sound lower quality or less controlled and usually isn’t worth the excess space they take up. 

Subwoofer enclosures that are too big can make the driver exceed its mechanical limitations. The bigger box can also increase vibrations and distortions. For cleaner sound, it is better to get a bigger subwoofer with a  bigger box if you need a louder system than it is to fit a small subwoofer into a bigger box.  

How Can I Make a Car Sub Sound Louder?

A few small upgrades to your subwoofer can make it sound a lot louder. The first thing you can do is to change the cone in front of the subwoofer. Next, you can change the voice coil. Another great way to increase your subwoofer volume is by getting the speaker installed in a larger enclosure or a different enclosure type. But you should be careful not to choose an enclosure that is too large or it can make the sound output sound cheap or hollow.  

Final Thoughts 

Getting a subwoofer box isn’t for everybody. However, if you want to enjoy deep and loud bass, a proper subwoofer box is necessary. But, doing so is much easier said than done, which is why we recommend doing your research first. Then, hopefully, you can use our tips to help you find the best and loudest subwoofer box design for deep bass.
