So without any further delays, let’s begin and answer how to build a speaker box…

  • Screws
  • Wood
  • Wood Glue
  • Insulation - one good example is either a polyfill or fiberglass
  • Braces

How to Build a Speaker Box

The following is a step-by-step guide and tutorial on how to build a speaker box from scratch that you can easily do at home with ease—

First Step: Select a Subwoofer or Woofer and the Type of Enclosure

A woofer or subwoofer can produce sound with low base frequency, so it’s a great idea to build a subwoofer speaker box for home parties and the like.

The enclosures of speaker boxes come in various types and appearances: Do you like infinite baffle, sealed enclosure, or would you want to build a bandpass speaker box?

Well, first of all, you need to decide on the woofer that’s in accordance with your musical preferences and the definition of the enclosure that’s fitted to the aesthetics you’re going to install the speaker.

Second Step: Creating the Enclosure and Identifying the Dimensions

Then, you need to decide the dimensions. How big the speaker box you want to make should be? Is it perfect to build a speaker box for 6x9? Do you want to build a car speaker box? In order to determine how to build a bass speaker box and its dimensions, you need to draw it on paper or computer first and foremost. Doing so gives you the ability to obtain the proper measurement of the speaking box. But to help you with this matter, all you have to bear in mind is the formula of height x depth x width. 

Third Step: Cut the Wood

When making a speaker box, it is important to cut the wood accurately. The first step is to measure the wood according to the dimensions of the speaker. Then, use a saw to cut the wood along the lines that were marked. It is important to make sure that the cuts are straight in order to create a clean and professional-looking speaker box. After the wood has been cut, sand it down so that there are no rough edges.

During this process, you need is to carefully take note of the tiny details in the dimensions of the space. You have to double-check because these areas are a little challenging to take on.

Fourth Step: Assemble and Put the Pieces of Woods Together

Now, it is time for the part of the project on how to build a center console speaker box by putting the pieces together using glue. Once you have put them together, you can use adhesive tape and leave them be until they are fully glued up, which would last up to 24 hours. Also, you have to place it inside the insulation before installing the speaker driver inside.

Finally, screw the focal points in order for the build not to fall apart. Again, you have to wait for at least a day before you put the speaker driver inside the speaker box. You see, the driver is relatively heavy, and lifting them immediately after assembling the build would ruin the entire project.

Fifth Step: Speaker Box Customization

The final process is the fun part of the entire DFY project because you get to customize your speaker box based on your music and style preferences. However, it is a little technical and would require the assistance of an electrician. Although the structure is relatively simple, it is still confusing, to say the least, especially if you do not have the skill to do it.

You may get help from YouTube or Google, but it is best to seek advice from a professional.

You also have to remember that the same process goes on, even if the topic is how to build a custom speaker box fiberglass. The material is a little expensive, but I believe it’s worth the price considering the reliability it can give you.

Frequently Asked Questions about How to Build a Speaker Box

Now, the following are some of the common queries about the subject matter of how to build a speaker box—

What is the Best Material for Speaker Boxes?

The ideal material for building speaker boxes is plywood. And the reason why this is the case is that this type of wood is light and should be reliable enough to hold pieces together inside the speaker box. In addition, they are thin, which would not affect the audio quality of the speaker driver at all.

How Thick Should a Speaker Box Be?

To be sure of the speakers’ thickness, you need to opt for plywood than anything else. However, some plywood is thick and tough, which would be difficult for your speaker driver to generate sounds. In this case, it is important to take into consideration the measurement of ¾” or about 19mm MDF.

You can also opt for dimension with a measurement of ½” or 12mm MDF, or woofers that are 8” smaller would also do the trick.

What Sounds Better a Ported or Sealed Box?

The matter really depends on your preferences, but if you are going for a “boomy” vibe, so to speak, then a ported box would be appropriate. But if you are aiming for a speaker box that has a cleaner and richer tone, then a sealed box is the excellent choice.


Building the casing of the speaker box is not as complicated as it looks. Once you have properly put things in place, then the sound and built quality should be perfectly fine and dandy.
