Building your subwoofer box is a great way to make your home audio system. You can do this on your own, or if you’re a DIY-er like me, you can save some money and learn a lot along the way.
I’ve wanted to build a speaker system since I was 10 years old. It’s been one of my favorite hobbies for years. After building my home audio system, I knew I had to share this awesome hobby with other audiophiles.
In this blog post, we will go over how to build a subwoofer box from the ground up.
First, we will learn about the subwoofer box if you do not know what it is, then we will cover all steps to build our DIY subwoofer box. So let’s dive in.
Types of Subwoofer Box?
A subwoofer box is an enclosure that houses the subwoofer. Subwoofer boxes are designed to keep the low-frequency sound waves contained and to protect the speaker from damage. Subwoofer boxes are typically made of metal or plastic and come in a variety of sizes and shapes.
Subwoofer boxes are usually one of two types:
- Car subwoofer box
- Home theater subwoofer box
A car subwoofer box is the most common type of subwoofer box used in vehicles. A car subwoofer box is typically smaller and has a different shape than a home theater subwoofer box.
A car subwoofer box is usually made of metal and is designed to withstand the harsh vibrations of a car. The enclosure can be closed or open.
While home subwoofer boxes are the larger enclosures that are used in home audio systems and are designed to keep the sound waves contained and from bouncing around the room.
What Does A Subwoofer Do?
This is a great question because it has multiple answers. First of all, a subwoofer is not technically a speaker in and of itself. A subwoofer is essentially a bass speaker that you put in your vehicle to amplify the bass of your car or music system.
It’s similar to an amp. An amp works by amplifying signals, while a subwoofer does the same thing with different inputs. It takes a signal from your amplifier and sends it down into a woofer to be amplified by the subwoofer and sent through the rest of your system.
Steps To Build A Subwoofer Box:
Building a subwoofer box is a simple task, but you need to be careful when choosing the materials and installing the box.
Subwoofer boxes come in a variety of sizes and shapes. For most home and commercial applications, a box that is 5’ deep by 3’ wide by 4’ high is a good starting point.
For the best sound quality, a subwoofer box should be constructed of solid wood. It is recommended that you use pressure-treated lumber for outdoor use. Pressure-treated lumber is usually darker in color than other types of lumber.
Furthermore, the following are the steps that you should review to make a subwoofer box.
Step 1: Identify Your Needs
Before building anything, you need to know what you are building it for. This could be a system for a single room or an entire house. It could be for a family or a friend. It could be for a hobby or a business.
To make an informed choice on what type of subwoofer box to build, you need to identify your needs first. You may have the best intentions of making a nice home theater system with surround sound, but if it doesn’t fit your lifestyle, then it won’t be good for you.
Step 2: Make A Design Sketch
The main step in building a box is drawing out a design sketch. This will be your blueprint. You should use simple shapes such as squares and rectangles, but there are no rules here. If you are using a piece of cardboard for your box, try to make sure it has a rounded edge on one side.
Step 3: Decide On A Fabrication Method
There are two main types of subwoofer boxes. One is built with wood and the other with metal. While there are many variations, we will be focusing on the metal subwoofer box, as this is most common and will give us a more detailed look at the process.
This option includes using sheet metal and some type of fastener (bolts, screws, etc.). We will be focusing on using the most popular choice; sheet metal and sheet metal fasteners.
The process of building a subwoofer box can be a bit daunting to the beginner, but it isn’t hard. For example, a box can be made out of just one piece of steel or aluminum. All you need to know is that if it is easy to do so, use it!
Step 4: Measure, Cut, and Assemble
Now we’re ready to start measuring and cutting. In the following step, we will cut the boxes, using a table saw. To ensure that everything goes together correctly, use double-sided tape to attach your parts before you start to cut. If you don’t have a table saw, you can similarly do this using a miter saw.
Step 5: Add the Parts
The first step is to get your hands on some foam board. You can pick up a pack of 1 x 12 inches by 2 feet from your local craft store. This is the size you need for a DIY subwoofer box, but feel free to use the same size if you are purchasing one from a retailer.
As I mentioned earlier, you will also need to add the components. First, you’ll want to buy some speaker grills and speaker wires. These are small pieces of speaker wire that fit into the ports of speakers to protect them.
The speaker grills are made of aluminum or stainless steel and should fit snugly on your speaker’s port.
Speaker wires are made of copper wire and are used to carry the audio signal between the amplifier and your speakers. You will need approximately 40 feet of speaker wire for your DIY subwoofer box.
You can get speaker wire in different thicknesses, but we suggest going with 18 gauge wire. This will provide a bit more power to your subwoofer box.
Step 6: Final Assembly
When assembling the speaker box, you’ll need some tools to help you get the job done. You’ll need
- A pair of pliers
- An electric drill
- Drill bits
- A tape measure
First, you’ll want to cut out the center hole in the foam board. You can use a simple jigsaw or even a hole punch. If you are going to be cutting the foam board with a jigsaw, make sure to set it up properly to ensure that the saw is making perfectly straight cuts.
Then you’ll want to drill three holes at the bottom of the box. These holes will be used for the speaker wires and speaker grills. Make sure that you drill through the foam board, not the backside of the speaker box.
If you’re building a home, I strongly recommend getting a subwoofer box. They, really, really help with the bass in a room.
Not only that, but they’re fairly easy to make, and most of the materials are just common household items.
