Anybody use a program to design a sub enclosure to the woofer specs?
I have all the dimensions for a basic box enclosure but need to build it with modified angles and cuts to fit the space. I want to make sure all measurements are adjusted so the internal cubic feet stays within spec. and new dimensions to fit.
I've checked online but nothing really shows up?

I have a neighbor who's an engineer with CAD software and he could probably do it. Just checking here first to see what others have done?
