Does Subwoofer Box Shape Really Matter?

Subwoofer boxes come in different shapes and sizes. Often, people just neglect the shape of it, have you ever thought about the subwoofer box shape, does it matter? Well, let’s discuss it in this post.

Does subwoofer box shape matter? Yes, the subwoofer box shape does matter. The air in less volume produces high pitch sound, whereas air in more volume produces low pitch sound. Now, as a subwoofer does the job of low pitch sounds, it is clear that more air volume is important for good bass.

Overall, a small subwoofer box shape most likely can’t produce loud/perfect bass, so it has to be accurate neither big nor small in size.

A subwoofer does the job of producing low pitch sound also called bass and comes in a variety of sizes and shapes. However, when it comes to size, it surely matters.

The bigger the box, the louder sound you will experience. When you choose a subwoofer, the two things you should consider are the driver size and power. So, yes the subwoofer box size clearly matters. Let’s get deeper into this and also find out if the shape matters as well. 

Does The Subwoofer Box Make Any Difference?

You can find different shapes of subwoofers, squares, triangles, pentagons, circles. Well, we all agree to the fact that different shapes have different surface areas.

When we talk about the sound effect based on shape, we have to first understand how sound travels with respect to shapes.  

Talking about curves and edges, we get a large volume with high pitch sound when the shape has sharp edges. On the contrary, we let low volume and low pitch sound when the shape has curves.

So, we can clearly see how the shape of the subwoofer matters. A circular subwoofer is said to be the best for sound effects and we’ll find out why. 

A circular Subwoofer?

Let’s go back to how sound works. The sound waves travel in all directions and so they tend to form a circular shape. So, when the speaker is circular just like the shape of the sound wave, it helps to produce the best sound wave and hence giving good sound effects.

If we talk in terms of surface area, then the square shape provides more surface area and that’s one advantage. However, circular subwoofers are best for sound quality and they are widely used

Now that we know how the shape of the subwoofer affects the sound, we now move on to how the size of the box matters. 

Does Subwoofer Box Make Any Difference?

When we look into how the subwoofer works, we find out that the box plays a role in its functioning. A subwoofer produces sound both from the back as well as the front.

The function of the enclosure box here is to contain the frequencies at the back to maintain sound uniformity. Without the box, the frequencies at the back would cancel the frequencies at the front. 

If we talk about the shape of the box, then the answer is pretty clear that the shape of the box wouldn’t hinder the sound quality. However, if you are building a box by yourself you have to make sure you meet all the parameters to make the enclosure. 

About the shape of the box, whether it is a sonotube type, square, or rectangle, if you build them properly by sealing all edges then you should get identical sound quality from all of them.

You also have to ensure that the pressure absorption of the sound takes place equally along the surface to cancel out the vibrations on the wall. 

With the size of the box, we discussed at the beginning of the article itself that the size of the box matters. Now, we’ll look into the reason for the same. 

How Does Subwoofer Box Size Matter?

The subwoofer box size matters as the sound that is produced depend on this factor. Firstly, for achieving low frequencies, the surface area plays an important role. Instruments like the tuba and pipe organ can produce notes lower than the human hearing range, which is about 16Hz.

However, they produce sounds that you can hear and feel by the harmonics, and so your stereo sound system should be able to do the same. We won’t get deep into this matter. 

For the best bass, the rating of 20Hz to 120Hz is said to be optimum. The lower is the frequency, the more mass you will get. These things fairly explain how the size of the subwoofer box matters for the sound effect. 

What Happens If The Subwoofer Box Is Too Big? 

A bigger subwoofer box indicates a bigger surface area. We discussed earlier that to produce low frequencies it is important to have more surface area or more volume of air. Well, we can acquire that with a big box to get the desired results. However, if the box is too big then there can be problems. 

If your subwoofer box is too big then reaching the mechanical limits of the subwoofer gets easier and unloading can occur. Unloading occurs when the sound produced falls below the tuning frequency. This unloading can damage your subwoofer. 

What Happens If The Subwoofer Box Is Too Small?

A small subwoofer box means a small surface area. When the surface area is too small, problems with coupling the surrounding air arise. With such a condition what happens is, at lower frequencies, there is no linearity in the sound produced.

As the frequency keeps going down, for good bass, it is important for the surface area to increase dramatically. 

For a small surface area, the volume is also effectively low. At low volume, the movement of the speaker experiences a dampening effect. Too small volumes increase the dampening effect, causing frequency loss and institute distortion. 

Conclusion:

I hope now you have a clear idea about how the shape and size of the subwoofer matter. However, it is essential that you get an ideal size of subwoofer box as too big or too small sizes clearly don’t work.
