There's a reason folks publish plans for horns, but not for simple sealed boxes... the latter are a lot easier to build, and most folks can see that's needed. I'm not familiar with Bill's work, but I would take brian6751's advice seriously if you choose to go ahead with the build. You may be able to find a lumber store that will cut things down for you, but 6 square panels will be cheaper than the odd cuts of a horn design. I've built horns, and they do work very well, but I would never suggest someone your age start there, unless you had lots of woodworking experience or a supervised shop.
Stepping back, the only trick to building rectangular boxes is accounting for material thickness. It's easy to calculate interior volume by subtracting 2x material thickness from outside dimensions. A simple box results from:
- 2 panels outside dimensions
- 2 panels inside dimensions
- 2 panels ID in one direction, OD in the other.
The first and third pairs form a cylinider, the second pair are plugs in the ends. And if you can get straight, square cuts, any good wood glue and clamps are all you need to assemble. Then there's the holes....
