Building Your Own Speaker Enclosures - Part 1
This speaker box calculator or subwoofer box calculator will help you determine the boards' measurements to cut when building a speaker box of your own.
We can also treat it as a speaker box volume calculator as it can also help you find your speaker box's internal volume depending on its dimensions, board thickness, speaker driver displacement, and tube port if needed.
As a bonus, we have also included in this tool a speaker driver displacement calculator for your convenience. In this calculator, you will also learn some guidelines on how to build a speaker box and how to calculate speaker box volume yourself or, how to find the volume of a box in general.
At the end of this text, don't miss our sample calculation for a inch speaker box. Keep on reading to start learning! Building your very own speaker or loudspeaker, whether it be a full-range speaker, a woofer, a mid-range speaker, or a tweeter, is a fun experience. It challenges our creativity, most especially in terms of woodworking, electronics, and our understanding of sound. Building a speaker box means we have full control over its design and size , not just over the speaker driver you want to use, but also over the sound quality.
However, in this basic speaker box building guide, we only focus on the speaker box itself, the volume displaced by the speaker driver , and the speaker tube port if ever we need it.
Keep on reading to learn more. Building a speaker box is like building any kind of wooden box, except that it doesn't have any moving parts like lids or covers.
We cut boards of wood or fiberboard to size and assemble them into a closed box with proper sealing , using enough glue or caulking on the joints. On the other hand, we can also see in the example above that the side panel's width is the same as the speaker box's depth.
The measurements of the panels depend on the design of your speaker box. Our calculator offers six designs for you to choose from, as you can see in the assembly case field of our calculator. Now that you know how to build a speaker box, let us now learn how to use our calculator to easily find your board panels' dimensions. Our speaker box tool is packed with a few features that will help you get started in building your speaker box.
Here are the steps on how to use our speaker box calculator:. Once you've chosen the assembly case, the next step is to enter your speaker box outside dimensions. That is its width, height, and depth. The next step is to input the thickness of the board you want to use. Upon filling in this field, the internal volume of the box field will already show a calculated result. After inputting this, you will find a board-cutting guide at the bottom of our calculator. If you decided to install a speaker tube port, select Yes in the Are you making a ported speaker box?
Doing so will reveal the port diameter and port length fields for you to fill in. This will update the value of the internal volume of the box accordingly. You can also input a particular port volume for other port shapes provided you know its value. Having this feature also makes this tool a subwoofer box calculator. If you already have a speaker driver , you can select Yes for this next field to display our speaker driver displacement calculator.
Input the required values for the cone diameter , mounting depth , magnet diameter , and magnet depth to calculate a speaker driver's displacement and automatically update the box's internal volume.
To estimate the speaker box volume, we need to determine the box's internal dimensions and multiply them together. Typically, the board thickness is uniform throughout the speaker box's body. With this concept, we can formulate the speaker box volume equation as follows:. However, the internal volume of the speaker box decreases when we introduce our speaker driver and ports. In this calculator, we approximate the speaker driver's volume displacement by evaluating the cone formed by its cone casing and the cylindrical volume taken up by the speaker magnet.
Knowing how to find the volume of a box for our speaker is also beneficial especially when the speaker driver supplier indicated the required average internal air volume for best sound quality.
The speaker box's internal air volume actually tells us something about how the speaker driver delivers sound. The smaller the speaker box volume is, the less air there is inside. This air can then be compressed easily, acting as a shock absorber for the speaker driver's vibrations.
This results in more control of the speaker cone to handle a wider range of frequencies. On the other hand, a speaker box with a larger volume reacts oppositely and typically requires installing a port in the system.
You can learn more about ported speaker box in our port length calculator. Let's say our inch speaker driver's displacement volume is around 0. Let's also say we wish to include two cylindrical tube ports that take up a total of 0. If it is within the range, then we can now transfer the measurements to our board for cutting. Embed Share via.

Sample calculation of speaker box volume. Building a speaker box Building your very own speaker or loudspeaker, whether it be a full-range speaker, a woofer, a mid-range speaker, or a tweeter, is a fun experience. How to build a speaker box? The first step in building a speaker box is to decide on its design and size.
If you are keen on clean audio and deep bass, your best choice is a ported speaker box. On the other hand, if you are not much concerned by the bass, a sealed speaker box should be your go-to option. Here is a side-by-side comparison of the sealed left and ported right speaker boxes: Once you've decided on the size and design to build, the next step is to determine your speaker box's board panels' measurements.
We can calculate each panel's dimensions depending on the speaker box's dimensions and the board's thickness. From the sample illustration below, we can see that the front panel's width is smaller than the speaker box's width by twice the board's thickness. This also holds with the side panel's height. After cutting your boards, it's now a matter of assembling the panels to form the speaker box. We can butt-joint the board pieces together or miter them for a seamless look.
However, butt-joints are stronger and easier to do than miter joints. Butt-joints are also easier to seal and are still aesthetically pleasing. Here are the steps on how to use our speaker box calculator: Choose the assembly case you wish to make. At first glance, each assembly might seem to be identical. However, during the actual assembly, you might consider recessing a face or two to give your speaker box an added character.
You can choose case 1 or case 2 to have the front side recessed, as shown below, or case 3 or 4 to recess the side panels. It's your choice. Input values. Assembly case. Case 1. Height h.

Online Loudspeaker Enclosure Calculation
One of the most popular pastimes in the DIY audio world is building loudspeaker systems. A web search will reveal literally thousands of different designs, a great many of which are at least superficially quite similar. We can be fairly certain that some of the published designs will sound very good, and others awful. This is reflected in commercial offerings as well. There aren't many 'real' audio brands that will be truly awful, but there will be differences. This is often despite the fact that many will show frequency response both on and off axis to be very similar, with many sharing one or more of the same speaker drivers as used by other manufacturers.

Use your crossover design software to decide a. An enclosure design software is supposed to help a designer calculate the optimum dimensions of the predefined geometry of a speaker cabinet. Such a geometry includes the box and the ports -if any- as well. The optimum amount of sound absorbing material is also expected to be determined. Ideally such a software should evaluate the SPL response of the bass drivers and the ports -if any- at a nearby reference point usually on tweeter axis at 1m for a frequency range of 20 to Hz. These responses should be as accurate as possible.
Enclosures for mini and micro speakers are similar in purpose to those for larger speakers; to protect the speaker and to enhance the audio volume. Enclosures designed with a few simple guidelines will meet the needs of most applications. A speaker consists of a diaphragm suspended in a rigid frame such that the diaphragm can freely move forward and backward. A coil of wire is attached to the diaphragm and suspended between the poles of a permanent magnet.
