Audiophiles and music lovers are always looking to enhance their music systems. The bass heads are always looking for ways to make their music machines deepen the low frequencies. Nowadays people generally tend to buy music systems that come with a subwoofer. Some of them build their own music systems and add a subwoofer to the gear so that the high, mids, and lows are all clearly audible. While a subwoofer alone is enough for producing deep bass, a subwoofer housed in the best subwoofer box can create a significant difference in your audio quality. 

The primary role of the enclosure is to prevent sound waves generated by the back of the cone of the subwoofer from interacting with sound waves generated at the front of the device. If these two sounds interact with each other the music produced will be distorted. 

The secret to getting the right bass is focusing on the bass that you like. Do you like tight and accurate bass or do you like loud and boomy bass with vibrations pounding away around you? There are two types of boxes you can choose from a ported box or a sealed box. 

A ported box features a smaller box size with tighter, more accurate bass. The subwoofer you have will need to pump more power for louder bass. Each beat in a tight bass setup plays crisply and accurately with no ringing after it hits the sides of the enclosure. The sealed air inside the enclosure acts as a shock absorber, and modulates the subwoofer cone’s back and forth motion, so all the notes get produced evenly. A sealed subwoofer has a flat frequency response and tends to play tight, full, and deep bass.

If you like boomy bass, then a ported subwoofer box is your best choice. Even though the bass is less accurate it is louder and boomier. A ported subwoofer box has a larger box size compared to a sealer subwoofer box. It is more efficient as it doesn’t require as much power compared to a ported subwoofer box. This is because the cone has greater freedom of motion. The port redirects sound from the rear of the cone and adds it to the sound emitted from the front, making the bass louder. 

Another reason for ported subs being louder is the fact that the air flowing in and out of the port creates an audio effect like that made by a whistle. The resulting tone adds to the tone emitted by the subwoofer strengthening the audio produced. Since a ported subwoofer enclosure is larger, space availability is a key factor while choosing the best ported subwoofer box. 

Another type of subwoofer enclosure is called a bandpass box. Bandpass boxes are on the larger side and are a combination of a sealed and a ported design. The design includes two chambers where the first one is a sealed enclosure that houses the subwoofer, and a ported box is built in front of the sealed chamber. This design creates a louder and more accurate bass than sealed and ported subwoofer enclosures.

Listed below are some of the best subwoofer boxes that are worth your money.

Final Verdict

Our recommendation for the best subwoofer box is the Sound Ordnance BB692W. Made of high-grade MDF, this box is solid-built and highly durable. It is a sealed box therefore, it produces accurate bass. This is a compact box and can easily fit in a smaller car or under the seat of your truck. This can protect your subwoofer from external heat and keep it airtight for maximum performance. 

Accuracy and best bass tone are two sound qualities cited by the proponents of sealed sub enclosures. Moreover, boomy loud music is preferred by those music lovers with a favor for pop songs and rap tracks. Besides, the best subwoofer box is really a matter of quality vs loudness. When choosing a subwoofer enclosure for your system, don’t forget to consider what sound qualities you like in the music. This will ensure that you get the right bass out of your system. 

Some of you might consider building your own enclosures. If you are skilled with wood and drilling machines and the technicality of a subwoofer box, then building one would be great and more cost-effective. But, if you want to save yourselves all that work and time, you can choose from the boxes available in the market.

Some of the aftermarket enclosures may come with a few defects. Therefore, it is better to work on the enclosure a bit to make sure that the box you invested in lasts you long. Apply additional wood glue to every wall joint so there are no possibilities for an air leak. Air leaks can mess with the sound quality of your subwoofer system. 

If you are installing the subwoofer enclosure in your car, make sure you place it somewhere away from direct sunlight. Heat can be detrimental to your subwoofer. The best place to install your sub enclosure would be in your trunk or under your back seat. This will ensure a more balanced sound. 

Buyer’s Guide


There is no one size fits all formula for subwoofer boxes. You have to measure the size of the subwoofer first and also the space that you are going to install the setup in. Manufacturers usually indicate the recommended size of enclosure for each speaker. Make sure you go through the specifications before you decide to buy one. 

2.Type of the subwoofer box

As mentioned earlier, there are three types of subwoofer enclosures. Choose the one that best suits your music taste. If you occasionally go on trips in your car and like to stop at places, blast out music, and enjoy nature, the best subwoofer box for you will be a ported one. 

3.Mounting depth

Check your subwoofer’s mounting depth before you buy an enclosure. The sub’s mounting depth should always be less than the enclosure’s depth so that there is enough space between the cone and the interior surface of the box. The space behind the cone allows for proper air movement and optimum sound production. If the space between the cone and the rear of the enclosure is too small, the sound volume will below. Also, the chances of your subwoofer overheating are high.
