Besides giving you a weekend project to work on, building your subwoofer box means you can save a considerable amount of money too.

Building a box can take around an hour and a half to a day based on the design, complexity, and skill level.

This article will tell how to build a subwoofer box that can meet your expectations.

Getting Started:

Without a doubt, you need to take the subwoofer and the manufacturer's guidelines before starting on the box.

This is a crucial step, especially if you are working around limited space.

Also, specifications like the box volume can help you decide how big you need to make the enclosure for optimum performance.

Building a sub box does not require you to spend a lot of time picking the materials and tools either.

First, make sure that you have MDF boards of suitable thickness on hand, along with the carpenter's glue, silicone caulk, and non-hardening rope caulk. ¾ inches is the recommended thickness for the MDF board usually.

Often, there is a debate about the pros of using MDF over plywood but stick to MDF for better results.

You will also need drywall screws, Panhead sheet metal screws, an electric drill, and a table saw to put your subwoofer box together.

Picking a speaker terminal cup is another step that you should pay keen attention to.

Step-By-Step Guide On Building A Subwoofer Box:

Step 1: Determining the dimensions

Determining the box's minimum depth, height, and width beforehand is essential to the box's design.

For fixing the depth, measure the depth of the subwoofer and add two inches to it.

Similarly, measure the frame diameter to determine the minimum height and width.

You can also find these dimensions mentioned in the user's manual.

After measuring the subwoofer, please compare the size of your box to the space you plan to place it in.

Then, sketch out the box accordingly; you can come up with a rectangular or a wedge-shaped box depending on the space available.

Step 2: Cutting the MDF

Once you have figured out the interior and exterior dimensions of the box and sketched out your design, you can move on to cutting the MDF.

It is often advised to make the front of the double box thickness to need two identical pieces in that dimension.

Using a saw, preferably with a blade lined with carbide, cut out seven pieces of the MDF.

If you do not feel comfortable with handling a saw or do not have the necessary tools at hand, certain home improvement stores offer their services at a small fee.

You can use the template that comes with the subwoofer to cut out its position on the MDF.

Step 3: Putting it together

Now that you have your pieces put them together using both glue and screws.

If you have opted to make the front panel twice as thick, use carpenter's glue to piece the identical cutouts together and a couple of sheet metal screws to reinforce it.

Also, use bracing while putting the box together if it is more significant than a cubic foot.

This is recommended because the box will be under extreme internal pressure.

Finally, before putting the back panel in its place, be sure to make a rectangular hole to hold the terminal cup.

You can place the terminal cup here after running some silicone caulk carefully around the edge and screw it in.

Step 4: Cleaning up

As you put together the subwoofer box, you will notice the carpenter's glue leaking out from the edges.

It needs to be wiped off from the exterior, but it is safe enough to leave it inside, even after using screws to secure the box.

While fastening the pieces, make sure that the box's small and large sides overlap to provide sturdiness.

If you find that the size of the box is smaller than the intended design, perhaps there is a fault in the way the box was aligned.

This can be easily fixed.

Step 5: Placing the subwoofer

After the box is fastened and tested for strength and stability, but the subwoofer in to see if it fits.

Use sandpaper to enlarge the designated position, if needed, and mark the screw hole locations with a pencil.

Remove the subwoofer and drill in the holes for mounting it. Before placing the subwoofer for the final time, line the edges with some silicone caulk.

Let it sit for a day or half before putting the subwoofer back in.

Step 6: Finishing touches

Once the silicone caulk has cured, you can hook up the wires from the terminal cup. Use the non-hardening rope caulk to hold it in place.

The naked MDF exterior is not appealing to the eye so, use vinyl or carpet to amp the looks of your DIY subwoofer.


Following the guidelines outlined above, you can make a good-quality subwoofer box.

If you feel like the box lacks personality, feel free to customize it.

Approaching a professional at a home improvement store can get you many ideas on innovation and installation.

Make use of all the advice you can get and make your next favorite sub-woofer box now.
