Good FREE program for designing enclosures?

[joe_prince 4]

I already have google sketchup and i'm wondering if there are any other softwares to design a box on?

I prefer to do it by pencil and paper and then draw it out on Sketchup.

I use this .... PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES for calculating port

This to calculate internal volume .... Enclosure Volume Calculator (EVC)

This to calculate port velocity .... LinearTeam

And this is a great read .... JL Audio - Car Audio Systems

Good luck!

Thank you for all the links. Any other suggestions?

Anyone know what this is--- Enclosure Build for CoCook83 (One 12 Inch SSA DCON) - SSA Car Audio Forum (the first picture)
