Subwoofer Box | Explained

Subwoofers are quite trendy nowadays and just like many others; you would have fussed through different subwoofers, hoping to get the best one. The thing that is most commonly ignored here is a subwoofer box and to be honest, it demands the same devotion and struggles as you spent on choosing a subwoofer.

For a subwoofer to sound the best, it requires a suitable enclosure, and this means your choice has to be perfect to enjoy the full bass of your new audio gear. Although you can also make a subwoofer box on your own, I recommend buying one.

Here is a short guide that will help you choose the best subwoofer box.

Subwoofer Box | How To Choose One

As mentioned earlier, to get the most out of your subwoofer it requires a proper enclosure and your selection must be a professional one. There are different factors to consider when choosing a subwoofer box.

A poor decision might spoil the bass! You have to choose between a sealed, ported and a bandpass box.

Sealed Enclosures

The sealed enclosures are considered the smallest in size and hence more compact to easily fit in your car. They also help prevent air from escaping the box that makes harder for the sub to move in and out ultimately increasing the transient response. This means you’ll get a tighter bass with great sound accuracy. One downside of sealed enclosures is that their sealed designed doesn’t allow the subwoofer to cool down easily as the air is not allowed to escape.

Ported Boxes

Ported boxes or vented boxes have a unique design with a port that is tuned to a specific frequency. Not to mention that as compared to the sealed and bandpass enclosures, ported boxes are the most efficient and gives you the best sound experience.

Because of their unique design, they can produce more sound output and the vent also gives back waves along with the front ones. They are touted to generate a deeper bass, however; its power handling below its tuned frequency is poor thus making the sub prone to damages.

The sealed boxes are perfect in this regard as they tend to provide a better transient response.

Bandpass Enclosure

Finally, we have the bandpass enclosures that lies somewhere between the sealed and ported models. This means they have one sealed and one ported chamber that gives you the experience of both the enclosures at the same time.

Similarly, bandpass enclosures also offer off the charts power handling with an exceptional low-frequency response. While you can opt for any of the three enclosures still, I recommend the bandpass box for optimal performance.

One plus point of bandpass boxes is that their ports are not tuned to speaker requirements, and most of the subs you use will perform better naturally.

While subwoofer box is important, you can also boost the performance of your subwoofer by adding a polyester fiber fill. It helps a lot in dramatically improving the overall sound quality.

Best Subwoofer Box | 12-inch subwoofer

You simply can’t enjoy the audio without having a powerful bass on the backend, and this can be made possible with a high-quality 12-inch subwoofer. The rumble that it produces in your chest feels great.

We all wish to have one of such subwoofer but with a plethora of options out there each with different specifications and features, it can be a bit daunting to choose the best one.

So, in this guide, we will take a sneak peak of How to Choose the best 12 Inch Subwoofer that complements your home audio system and is efficient in the long run.

Choosing the Best 12 Inch Subwoofer

Buying a subwoofer is not simple. You have to choose the right blend of size, amps, watts, frequency response and performance to get the most out of your subwoofer.

So, here are some things to consider!

1: Features

Most of the subwoofers in the market come with a built-in amplifier and a crossover. Some may not have this feature. Make sure that you choose the one with a built-in amp!

The crossover feature gives your subwoofer a steep slope with a wide cutoff frequency adjustment range that complements nearly any speaker.

Also look for the RCA jack. Usually, all subwoofers have a line level input with RCA jack. It helps those using an AV receiver, stereo preamp or a surround processor. Those using a sub with a stereo system with no sub crossover, go for a model that offer speaker level inputs.

If you opt for the expensive models, they have automatic EQ function with a microphone that can be used to adjust the sub’s response to comply with the acoustics of your room.

Sealed, Ported & Passive Radiator?

  • Sealed: These subs offer a tight and punchy sound but have less deep bass output.
  • Ported: These subs produce a loose and a boomy sound but have a deep bass output that makes the sound quality incredible. However, ported subs are quite bulky and the air moving through the port causes too much chuffing that may feel awful.
  • Passive: These have an acoustical functionality same as a port, however; they are more like the sealed models.


This is where things start to get a bit complicated. You can easily get confused when every brand subwoofer you see is claiming to be the best in its specs. A major factor to consider here is frequency response measurement that is performed at low signal levels.

Some average subs have a response below 20 Hz while the powerful models can roll off below 35 Hz. However, there are more efficient subs, but they are expensive.

You should never ignore the frequency response measurement of any manufacturer.

One, Two or Four Subs

Finally, you have to decide on which sub to invest. With more subs, you will have a better response in enjoying the sound.

12-inch subs are best in this regard as they are tuned to the same resonance bandwidth.
