Subwoofer Box Buyer’s Guide

Size and Design

While the product’s appearance doesn’t always equate with its quality, the design of the enclosure is a critical subject to tackle as it has to blend into the existing system and exterior at the same time. 

You must remember that not all subwoofers could work in every type of enclosure, so it’s best that you evaluate your needs first. 

Do you need a single or a dual box? Do you have a specific audio preference that you want to achieve? These questions must be answered before you proceed with picking a box design. 

In addition to this, the location of which you’ll place the enclosure is another factor you should also take into consideration. There are some boxes not suitable to be placed in certain locations, and buying these designs may affect the quality of sound you intend to produce with your woofer. 

On the other hand, it’s also important that you check on the actual size of your woofer before buying any type of enclosure. The worst-case scenario is you purchase a product that doesn’t have the same measurements. You’re lucky if it can be returned. If not, then it’s a waste of time and money. So to avoid this hassle, check the proper sizes ahead of time. 

Incompatible enclosures could also damage your subs permanently due to excessive vibration and distort the audio quality caused by that extra space. 

Single or Dual Subwoofer Box?

As previously mentioned, woofer boxes have two types of designs. The first one is the single enclosure, which could house one sub and is mostly used for the intention of producing quality sound. In contrast, a dual-sub housing is added if you’re aiming for louder sound output. 

While a single chamber gives more excursion relief that prevents excessive cone movement, dual boxes offer less distortion even when played in the midrange frequencies. At the end of the day, picking between dual or single boxes also depends on the placement of the subwoofers.

Enclosure Type

As you may already have noticed during the product roundup that our resident audio experts conducted, there are different types of woofer enclosures that could accommodate your audio needs. Each of these features functions suitable for distinct preferences and requirements, so let’s dive right into it. 

Sealed

If you’re someone who prefers to hear smooth and accurate bass lines during your listening activities, then sealed enclosures are the ideal option for you to get a well-balanced flow of music. Compared to ported and bandpass boxes, sealed designs tend to have better low-frequency capabilities. 

On top of that, you can expect that the transition of audio waves in sealed speaker boxes is always accurate and clear. However, because these types of enclosures are airtight and can release much heat, they can have higher maintenance than others and be prone to damages. 

It also requires more power, which ultimately means that you’ll easily identify distortions in certain volume levels that it cannot accommodate. 

Ported

Unlike sealed enclosures, ported designs are meant to add an extra layer of booming bass response to your existing subwoofer and require lesser power. The integrated port has the ability to mimic an actual speaker that’ll eventually result in better sound.  

Given that a ported subwoofer enclosure isn’t sealed, the airflow inside the enclosure could freely navigate and allow the frequencies to produce a low heart-thumping slam. Another perk of choosing a ported option over others is that it’s also more suitable for extended usage, without the fear of wearing it down or damage. 

On the downside, these types of enclosures may appear complex and hard to assemble with other speakers. You may need to use a subsonic filter on the amplifiers to achieve the cleaner tones you intend to achieve. 

And even though it’s not tightly sealed, the heat inside the box has the tendency not to spread evenly, often resulting in rough distortions when played for longer hours. 

Generally, they are also larger in size. So you may need to consider your available space before proceeding to buy this woofer box for your available unit. If you’re not familiar with its setup, the best recommendation our sound experts could give is to seek advice or assistance from audio professionals out there. 

Bandpass

Last but not least on the list is the bandpass subwoofer box. This kind of enclosure has the impressive capability to pass massive audio output in a small opening. To put it simply, a bandpass box design is a combination of ported and sealed enclosures. 

In this set-up, the woofer is placed inside a dual-chamber, one of which is the ported, and the other side is the sealed one. Although a bandpass box design isn’t an entirely new concept in the audio technology market, there’s no denying that it was the most used enclosure in many residences. 

It offers a vast range of customizations in terms of audio and bandwidth, greatly owing to its excellent transient response. Considering the quality sound it produces, you also don’t need to worry about its durability as its cone movements align accurately on your desired frequency. With its super-efficient sound range, you can enjoy hardcore rock, reggae, or rap to the fullest.

Moving on to the cons, as you may already imagine, bandpass boxes can be hard to configure and require a bit of a complex setup, unlike the other two. The same predicament applies when the chamber runs into technical trouble, you may need assistance from a professional if you’re not familiar with its arrangement. 

Besides that, the interior of the box is relatively smaller than you think, so the frequency response will solely rely on how you tuned and configured your woofer to match this type of design. 

Material Quality

Given the fact that you’re looking for the perfect box design for deep bass, it’s only natural that you examine the quality of materials used on these subwoofer boxes. Otherwise, you’ll end up in a repeated cycle of buying and replacing stuff again and again. 

As these enclosures have to withstand strong pounding and forceful bass, selecting a product constructed with MDF is an ideal decision to make. You may have already noticed that most of the products we included in this list possess that quality to ensure added durability and better sound qualities. 

Aside from MDF, other common materials used for a subwoofer box design are plywood, fiberglass, polycarbonate, and aluminum sheets. You may be surprised, but plywood is among the best ones to choose if you want to achieve a better-sounding bass. This option is known to have thick, sturdy, and affordable components that’ll perfectly suit your woofers. 

There’s also fiberglass. This type of material could also bring out good output as it is known as a light, strong, and weather-resistant component. 

While the materials of the boxes really do have an undeniable impact on the durability of the product, always keep in mind that the way you use it is also a huge factor. You must know how these components must be treated and maintained in order to make use of their maximum leverages.  

Airspace

When buying or creating subwoofer boxes, it’s essential to calculate how much airspace your speaker may need [1]. Logically, a 12-inch sub will need more space than a 10-inch device to accommodate the flow of sound waves in the speaker box properly. 

For example, if your subwoofer has a 6-inch driver, it’s wise to buy subwoofer boxes with approximately 0.3 to 0.4 cubic feet of airspace available. For 8-inch subwoofer drivers, you can choose between airspaces of 0.6 to 0.8 cubic feet. You can easily do this calculation by doing the height x width x length method and divide to one cubic foot. 

For a more straightforward process, you can consider the typical rule of thumb where you always have to increase the volume you’ll need by 20% to ensure the utmost accuracy.   

Keep in mind that the best subwoofer box design for deep bass is the one that aligns with the needs of your unit. It doesn’t matter if your slot ported box or sealed box has the grandest exterior; if it doesn’t have proper airspace for your woofer, then expect lesser quality sound. 

Why Purchase a Subwoofer Box?

After reading the product roundup and the buyer’s guide, you may already have gotten the sense of what a subwoofer box is for. However, in case you’re still not convinced yet, let our audio enthusiast enumerate why you need to buy one for your woofer. 

Without a subwoofer box, the sound coming out from your speakers would collide and result in the audio sounding flat and distorted. Housing your woofer devices inside these enclosures secure noise-cancellation and result in better sound frequency. 

It allows maximum reproduction of bass that has the potential to interrupt the sound signals if not tuned in properly when you play music.
