Different Subwoofer Box Sizes or Enclosures

You probably know this, but for the sake of overall understanding, I’m going to briefly go through the different sizes of the Subwoofer box

As the box size depends on the subwoofer size and based on that, the box can be categorized into four categories.

Small Boxes: Small boxes are usually two types: eight inches and ten inches. You will find these in the smaller cars on the stock systems. 

The eight inches can offer overall quality without giving up a lot of space in your vehicle. Even though ten inches might seem a bit bigger, they are almost the same as eight inches. 

Medium Boxes: The boxes around 12 inches are medium-sized subwoofers. It’s very common and perfectly balances the audio and the space.

Large and Extra Large Boxes: The large boxes are around 15 inches and more than that. These boxes are known for their ability to tackle long bass notes. But, it can be difficult sometimes to handle the cone.

Can A Subwoofer Box Be Too Big?

How Does Box Size Affect Subwoofer Sound

Yes, a subwoofer box can be too big if the subwoofer box’s size is 20, 18 inches, or more than that.

The audio output decreases when the box is much bigger than the subwoofer, but these bix boxes have a low-frequency extension. As a result, setting the audio to low frequencies will give you more and better output. 

But, if the box gets even more significant than usual, you will lose the output along with the low-frequency settings and frequencies.

I made a list for you to go through the advantages and disadvantages of a big subwoofer box.

  • As for the benefits, when the box size is bigger, you will have better access to the components of the woofers.
  • Besides, if you’re dealing with a big box, there is no need to add extra power to the system, as it is needed for the smaller ones.
  • You won’t need to worry about the coil temperature. As the driver has enough space to move through, the motion will be intact and easier to handle.
  • Sometimes it might be challenging to tune lower and overall port area management. In that case, more space might help and won’t result in port noise.
  • The shift curve might be a problem sometimes; in that case, you need to lower the response curve.

How Does Box Size Affect Subwoofer Sound?

The box size after the subwoofer sounds in various ways, such as sound quality, air volume, bass tones, and lower frequency notes.

Sound Quality: When using a small box, the sound won’t amplify as in big boxes. As a result, the sound quality will vary depending on your box size.

Air volume: It’s common knowledge that the bigger the size of the box, the higher the air volume is. And the air volume directly affects the bass tones and compatibility with the frequency notes.

Bass Tones: The more air volume in the box, the more deep the bass tone will be. You usually won’t notice the bass tones because you’re using a small box. Besides, too small boxes won’t be able to handle more bass frequency.

As a result, some frequencies will be too loud, and others will be too quiet. But that won’t be a problem in medium-sized or big boxes.

Q-System & Resonance: You will notice an increase in the q-system while using a smaller box. On the other hand, it decreases on the bigger boxes. 

When the q-system increase, the peak also increase in the resonance, and vice-versa. As a result, the more the peak is, the more sound will be boomier.

Control: A small box will be suitable if you want to control the sound and work with various frequencies. Thus, a small box makes it easy to power handle and decreases the cone excursion.

Compatibility with the Notes: The bigger the box size, the more compatible it is with handling powerful notes. Besides, the big boxes can catch the low frequency with clear quality; as a bonus, it will keep it free of distortion.

Volume: As you might guess, the bigger the box, the higher the volume. But the size of the environment or the room also matters. The bigger box will be a better option if you want more sound, mainly for the outside.
