Save wood, prototype your cabinet design in Free Google Sketchup:
Google SketchUp
You can find speaker cabinet examples under File->3d Warehouse
One you've drawn your cabinet, you can calculate the internal volume using one of the "Volume" calculators at:
Home - Ruby Library Depot
Hint: Temporarily plug the end of ports so they won't be considered in the calculated volume.
To derive a cut list for plywood and other wood components take a look at "Cut List" plugin. Cutlist and Layout from Sketchup - by daltxguy @ LumberJocks.com ~ woodworking community
