I have a friend who “loves his speakers”. He should, he designed them himself. It’s not something I would recommend to just anybody. My friend is an engineer by trade, and a person with an uncanny ability to focus and delve deeply into the principles behind the area of loudspeaker design. There were a ton of speaker cabinet design directions he could have gone with, but he settled on some very simple plans that allowed him to do some comprehensive math and acoustic calculations using software made for that very purpose.
Speaker Cabinet Design Basics
![Design Design](https://storage.googleapis.com/3d_model_images/322/3221548/subwoofer-in-box-3d-model-r5nTWXi8Q_200.jpg)
The first thing to decide before choosing a speaker cabinet design is what frequency range you’re going to achieve (or attempt). The frequency range–particularly the low frequency extension, will guide some basic dimensions related to the speaker cabinet design. H-PAS and other fancy porting solutions aside, the capabilities of the low frequency driver will ultimately interact with the speaker cabinet and affect your low frequency response and tuning.
There’s also the question of aesthetics. Do you want a floorstanding tower speaker, or a pair of bookshelves? Are you designing a full-range speaker or a subwoofer? I have yet to see any of my friends tackle a bipole or dipole speaker–and for good reason. Those are highly advanced designs that incur their own set of difficulties and design challenges.
Example: I want to go with a tower design that is ported.
Speaker Cabinet Shape Considerations
There are some very basic principles involved in calculating standing waves and the effects of a speaker on the enclosure (and vice versa) when you deal with a “perfect” cuboid shape. Get into a rhombus, however, and now you’re going to need more sophisticated software to understand what might be happening inside the cabinet and how that will affect your speakers.
After understanding the basic shape you want to start with, and whether you’ll want to do manual or computer-calculated designing (we recommend using a computer and then checking your work with plenty of listening tests), you then have to determine what other characteristics your speaker will have. Will the box be ported (also called a bass-reflex design)? Where will that port exist (front or back)? Will you opt for an acoustic suspension design (also called a sealed design)? Each of these considerations needs to take place before proceeding too far down the path of loudspeaker design. We’ll get into the software considerations later in this article. For now, just know that you have some preliminary decisions to make before going too far.
Example: I want a trapezoidal top on a ported cuboid base.
Crossover Design – Passive, Active, or a Kit
A crossover is a typical component in any loudspeaker design, though I have heard of designers custom-making speakers without the use of a crossover. In most cases, however, a crossover is needed to filter what frequencies go to the tweeter or high frequency driver and which go to the low frequency driver. Before you’ll be able to continue with your speaker design, you’ll need to understand whether or not your design will be active or passive. Chances are that you’ll be using an existing kit if you go with an active design since they are so difficult to design. Some, however, may opt to roll their own passive crossover network–perhaps based on a computer recommendation or an existing kit design. It all depends on how far you want to take or customize your loudspeaker design. Here is a great Excel-based application/file that can help you if you are interested in designing and building your own crossover.
Example: I’m going to use a passive crossover kit that should do what I need.
Speaker Cabinet Design Software
The next thing you’re going to inevitably want to investigate is speaker cabinet design software. While you can certainly design a box, do your own math, and add your own drivers, investing in a good piece of speaker design software will do wonders. We can’t list every piece of software here, but these are just some of the more popular ones, or ones we’ve been acquainted with in the past:
AJ Designer – AJ Designer speaker design software has the ability to help with bandpass, vented, and sealed subwoofer designs. The software provides an easy to use interface to calculate volumes of the front and rear chambers of the box, calculate box dimensions, determine the resonance frequency, -3 dB points for both the high and low pass filters, port length and diameter, frequency response plot, and power response.
Unibox – Unibox is more of a sophisticated spreadsheet than a piece of software. It operates under the principle that simplifcation is no longer needed and the full driver-box model can be implemented. The full driver-box model includes individual control of absorption, leakage and port losses. The software also includes graphs for sound pressure levels produced by port leaks, speaker impedance and step response. Unibox works for
Boxnotes – Boxnotes is software designed to help you design a subwoofer with appropriate dimensions for the goals you have. It accounts for extra volume taken up by your ports, bracing and driver; checks the minimum dimensions required to house your driver; lets you see the effect of changing port parameters; and helps you spot problem resonances and adjust your dimensions. It even prints your cutting list.
Winspeakerz – Winspeakerz lets you select a woofer for your home theater speaker from the driver database and load it into the software. You then select the type of enclosure you want to simulate (closed, vented or bandpass with a total of 18 different variations). You can then enter different volumes and tunings and run the analysis to analyze the effects. After deciding on the box you can then open the box calculator and have WinSpeakerz suggest your loudspeaker dimensions.
There are a ton more applications, some commercial (LEAP EnclosureShop, SoundEasy, Eminence Designer, etc) and some freeware or trialware (like this woofer box and circuit designer). If we didn’t include your favorite here, please leave a comment below, and we’ll get it added to the list.
Helps solving the required calculations for custom bandpass box cabinet designs
AJ Bandpass Designer is very easy to use and it can be used for car, truck, sport utility vehicle (SUV), jeep automotive, guitar and home theater applications and projects.
Successfully plan, design, construct, build and setup subwoofer enclosure systems using AJ Bandpass Designer.
Works with any type and size of driver (8, 10, 12, 15 inch). The Subwoofer Designer Series is intended for the hobbyist, audio / acoustic enthusiast and Do It Yourself (DIY) speaker builder.
Bandpass Designer provides accurate theoretical solutions for subwoofer driver characteristics and attributes (Thiele Small) and box/enclosure parameters with an easy to use interface.
There exists other calculations, not included in the software, because they are not required and provide little technical information.
As with any design or engineering of speaker enclosures, the performance, sound output, bass, and sub frequencies are not guaranteed.
Bandpass Deisgner calculates speaker parameters based on loudspeaker theory and engineering equations/principles/formulas.
Winiso virus. The calculations are used to predict loudspeaker parameters. This was noted, because not every loud speaker design will give the expected results.
