I'm trying to come up with a design for an reconfigurable enclosure for in box driver measurements. I'm thinking of a modular baffle that will allow me to test different driver sizes, positions and configurations. For the box maybe build a frame using 1 1/2 x 1 1/2 strips of different lengths pegged together. I would then just use a few layers of cardboard taped to the frame. Up till now I have been designing and building a complete enclosure, installed my drivers and testing, if I didn't like the results I'm left with a pile of scrap. What does every one else do?
