Boxnotes
Use this free software to assist you in deciding the actual dimensions for your enclosure
After using software such as WinISD to chose the volume and port sizes for your new speaker, turn to Boxnotes to find the best dimensions for your enclosure.
Screenshot showing use of Imperial units. Metric is also supported
Features of current version - V3.1
- Take into account the extra volume taken up by your ports, bracing and driver
- Check the minimum dimensions required to house your driver
- Quickly see the effect of changing port parameters
- Spot problem resonances and adjust your dimensions to minimise their impact
- Print your cutting list, including optional allowance for trimming with router
- Save your work in boxnotes project files, including comments
- Supports both Imperial and metric measurements
- Generate a text based report containing your choice of information
If you don't have them installed, you may need to grab the VB6 Runtimes - Windows XP already has them.
Notice: Minor error found in earlier versions of boxnotes
The driver-to-wall resonances shown in boxnotes versions 2.82 and earlier were wrong
They were calculated on the assumption that the driver acts as the open end of a resonant pipe
These experiments show that it acts as a closed end
The resonances are thus half-wave rather than quarter-wave and the frequency need to be doubled as a result
This error has been corrected in the current version (V3.00 onwards)

| Your program helped me to design a wonderful sounding sub that I could actually afford to own, LOL. Thanks as well for including the "system info" easter egg, that little tool is great! | Paul B, Australia |
| I was elated to find your "FREE" software.......thanks again for sharing your time and talent | Steiph Z ,Decatur, Georgia, USA |
| Thanks mate. I've been looking for something just to work on whats the optimum dimensions for my box. I know the volume it needs to be...but what's the best dimensions? Thanks, you're a legend. Great site..... | Shane S, Chicago |
| I downloaded Boxnotes yesterday and learned a lot from it. I think it's a perfect compliment to WinISD. Everybody who I've told about WinISD will hear about boxnotes next. Many thanks.... | Jim M - comment posted on WinISD support forum |
