You must be talking about the 12π basshorn subwoofer, since it's the only model with plans distributed as an AutoCAD file. See the post called "12π basshorn - Coming together" for a step-by-step pictorial writeup of the construction process. If you want, I can also send out some image files containing the drawing I did of the prototype. It isn't as accurate as the AutoCAD drawing, but it may be useful for you. It is drawn as a side view and it makes it easy to see the dimensions of each part.
