Serious sound enthusiasts are always on the lookout for ways to improve the way their audio systems deliver sound. One of the easiest and least expensive routes to higher-quality music is enclosing a speaker in an appropriate subwoofer box.
Most big speakers and subwoofers need an enclosure for several reasons. First, the enclosure gathers sound frequencies and directs them in the same direction. In the absence of an enclosure, a speaker can produce sounds of varying frequencies from both the front and the backside. Since these frequencies are not in unison, the overall sound quality is significantly affected. With a subwoofer box, this issue is rectified, so your sound drivers can deliver more accurate sound.

We set out to find the top-performing sub boxes in a bid to help you choose the best one for your speakers or subwoofer(s). As usual, our hunt starts from analyzing the market to know which brands are offering competitive products. In this first stage, we found out that Bbox, American Sound Connection, QPower QBASS, and Rockville are the heavyweights in the competition for the best manufacturers of subwoofer enclosures.
We reviewed offers by each of these manufacturers on the basis of aspects such as enclosure material, quality of construction, and durability. This step gave us a wide selection of best-performing sub boxes for each manufacturer. We intensified our selection criteria by adding price considerations as well as an analysis of reviews from major eCommerce sites. After analyzing the huge amounts of data from real customer reviews, we were convinced that the following top 5 subwoofer boxes satisfy our selection criteria as well as customers’ needs.
And, now, here are the winners of the top 5 sub boxes in 2022:
1. Bbox E12ST Sealed Subwoofer Box Enclosure – Overall Best
This Bbox sub enclosure boasts of being one of the strongest and best-performing sub boxes across all brands. Bbox designed every aspect of this box aiming at eliminating any noise or vibration for superior bass reproduction. Besides, the shape of the enclosure is ideal for installation in small spaces, as explained further in the features section below.
Features of Bbox E12ST Sub Box

With a mounting depth of 5.25”, a height of 15.25”, and a width of 19.25”, you can install the enclosure behind or under the seat of your SUV or pickup truck.
- The airtight seal between MDF parts: Bbox has used specially-formulated wood glue to join MDF pieces. Two applications of this glue make sure that all internal joints are airtight, and that the box stands strong after the final assembly. This effort complements the use of Miter joints, which offer more surface area than a traditional butt joint. More joint surface area and the use of competitive wood glue result in a tighter seal and a stronger bond between the MDFs.

Like many of the Bbox products, this box is manufactured to provide an economic solution that satisfies your needs. It is, therefore, not surprising that Bbox sells this premium-grade sub-box at a very pocket-friendly price.

Guide to Choosing the Best Subwoofer Box
Since there are many different types and designs of subwoofer boxes, it helps to understand the important considerations one should make when choosing the best box for your speakers. These considerations revolve around sizing, design, and construction material. Let’s discuss each of them in detail below:
Size of Enclosure
While it’s clear that a subwoofer enclosure increases the backspace for speakers to produce bigger sound, not any size can fit every speaker. The subwoofer or speaker you have will determine the size of the enclosure to buy. Manufacturers of speakers indicate the recommended size of enclosure for each speaker. Make sure to check these recommendations and search for the respective enclosure. If you have a 10-inch sub, for example, look for the best subwoofer box for 10” subs. The same applies to all other sizes of speakers and subwoofers.
Type of Subwoofer Box
The sound you receive from your sub will be influenced greatly by the type of enclosure to which you have mounted the subwoofer. The three main enclosure types are sealed, ported, and bandpass enclosures.
Sealed enclosures seal the sub in a box and give out the excellent sound quality. These boxes are best known for tight & accurate bass. They taking less space compared to ported boxes, but they also need more power to produce a higher quality of sound. Thus, your speaker system needs to be adequately powered should you plan to use a sealed enclosure.
Ported boxes are more efficient than sealed enclosures, and they give out louder sounds. If your focus is majorly on bass volume, then a ported enclosure is your best bet. The downward of using this type of box is that they take more space, so you might want to check your space requirements carefully.
Bandpass enclosures combine properties of sealed and ported boxes. In one compartment, the box is sealed, and the other compartment is vented. This enclosure type provides a significant bass boost while maintaining a good level of efficiency.
Installation Space Requirements
The size of a sub enclosure has more implications besides the kind of sound it supports. You need to consider the space needs of the location where you intend to install your completely mounted subwoofer. If you don’t have space limitations, go for any sub enclosure as long as it suits your subwoofer. However, if the only locations left for the installation of subs have limited spaces, then you have to think along the lines of space-efficient sub boxes like the ones we have reviewed above.
The common materials used to make sub enclosures include medium density fiberboard (MDF), standard wood, fiberglass, and plywood. Of all these options, MDF is most preferred because it is thick, sturdy, and durable. When choosing an enclosure made with MDF material, check its thickness to ensure that it is at least ½” thick. This thickness is enough to avoid sound distortion but the thicker the better. Fiberglass is a great choice too as it is strong and light. This material holds up to temperature and weather changes, thus it can maintain the quality of sound given out by your speakers.
Subwoofer Mounting Depth
The sub’s mounting depth should be less than the enclosure’s depth so that there is a gap between the sub and the interior surface of the box. Subs need enough space behind them for proper air movement and optimum sound production. If the space between the sound driver and the enclosure is too small, the sound volume attainable is limited, and the chances of subwoofer overheating are high. Thus, mounting depth is a very crucial consideration when buying or making a custom sub enclosure.
