Determine the volume of the box; Select Box Calculator from the Box Calculator menu; Enter additional volume value. Additional volume will include any space taken up by the speaker structure, braces, or anything else that takes up space in the enclosure; Select dimensions to constrain. Enter new values for the constrained values. Boxnotes - check your enclosure design for resonances, factor in the volume taken up by ports and print your cutting list Sonosub - design a cylindrical subwoofer. Check resonances and clearances Flare-it, - find the correct port diameter and flare size to avoid audible turbulence Subsaver - calculator for finding component values for a 2nd. WinISD is a great speaker design software that is designed for the Windows platform. The software is 100% free and offers quite a wide range of features. With this, it is easy and possible for the users to create vented, bandpass as well as closed boxes that will deliver quality sounds. We can provide you with comprehensive Subwoofer Box Calculator for online creating a high performance subwoofer enclosure. Build a ported box, sealed box for your low-frequency speaker.

| Your program has made me a very happy customer! I have made 3 enclosures that have netted a first place with one at its only show. Keep up the great work and thanks again - Keith Riggins, SFC FSTD |
The Subwoofer Design Toolbox by MFR Engineering is an easy to use but powerful program for designing subwoofers.Its convenient tab interface lets you choose from box design, port design, enclosure design and woofer selection tools.It runs on Windows XP, Vista, Windows 7, 8, 8.1 and 10. |
| The box design tool lets you design sealed, ported and bandpass boxes. It also includes 'free-air' modeling for auto sound applications. Simply enter your driver parameters, enclosure type and box volume. For ported designs, the program will recommend a port frequency or you can choose your own. Bandpass design is easier than ever before - choose a box volume and the port frequency is automatically optimized as you adjust the ported fraction of box volume. The Subwoofer Design Toolbox fully supports metric users too. |
| Use the Car Response feature to see the effect of operating your sub in a wide range of vehicle sizes. For home subwoofers or convertibles choose the flat setting. Otherwise, choose the setting that most closely describes your vehicle. |
| With the Subwoofer Design Toolbox, it's easy to compare frequency responses of different box designs on a single graph. Use the point tracking cursor to precisely identify frequency and magnitude points. Frequency response printouts can be in color or with symbols enabled to improve readability with black and white printers. |
| For ported and bandpass designs, use the port design tool to determine the correct port dimensions. Choose from round, rectangle or slot ports. Unlike some other programs, the Subwoofer Design Toolbox uses the more accurate divided chamber method for multiple ports. Context-sensitive design hints and recommended values assist beginners and pros alike. |
| The enclosure design tool helps you design rectangular and wedge-shaped boxes. Calculate the volumes of prefab boxes too. You can calculate box volume from box dimensions, or you can calculate any dimension by entering the box volume you want and the other dimensions. Just enter your numbers, then click the Calc button next to the parameter you want to calculate. After you've specified the enclosure dimensions, click on the Show Template button to view a printable Cutting Template for the enclosure pieces you'll need. |
| The woofer selection tool lets you quickly compare woofers without having to design a box for each of them. The Sealed and Ported Bass Response Figure of Merit rates 'how low the bass will go' compared to other drivers. The tool recommends when a port should be used. Estimated Box Requirements show you what box size to expect for a particular driver. |
| The Subwoofer Design Toolbox contains everything you need to design your own high quality subwoofer the easy way! |
Car Speaker Box Plans
There are quite a few different enclosure design software programs out there. The prices range from free to $1,000+. For most designs that the novice box builder will attempt there are a few I could recommend:
WinISD - WinISD is made available by LinearTeam. It's a very highly rated, free program for Windows. There is also an online version which isn't as full featured but can be run on any operating system through a web browser. This can be helpful for Mac/Apple users since MacSpeakerz has been discontinued.
Blaubox (click to download) - Blaubox has been around forever it seems. Created by Blaupunkt, it's a DOS program which may cause some run problems with the newest 64bit versions of Windows (try running it in 'compatibility mode'). It's free and definitely worth checking out. It even prints out the cut sheets for your car subwoofer box plans. If you still have trouble running it in compatability mode I'd recommend using a DOS emulator such as DOSBox. It's free and relatively uncomplicated to use.
DISCONTINUED MacSpeakerz - For the Macintosh users without a PC emulator there is a program out called MacSpeakerz. I haven't used it personally but it's fairly popular and virtually the only program made for the Mac. Provided by TrueAudio DISCONTINUED
You should also check out Advanced Enclosure Design and Fabrication. It covers designing enclosures using free computer software, maximizing the output of a subwoofer system, building the box like a pro and testing the output using inexpensive equipment. Click here.
