Using some 500 pound triple wall corrugate, fitted with Vifa A10CC-07 (made for M&K) two way drivers and Eminence Alpha 8 (Parts Express) woofers and a simple 3-way crossovers from Parts Express. They sound better than they have any right too. Actually surprisingly good.

They actually look quite good. How did you seal them to make them airtight?
These are made from two pieces. The sides and front are one piece that has been scored and snapped to form the pyramid shape. The back is a triangle that is glued in place with an industrial hot glue gun. There is no bottom.

And in case you were wondering what is triple wall, here is a little corrugate 101.

They look very nice..Is there any internal bracing? Even triple ply would have some flex I would have thought..
The board will resonate but will not flex in sizes as small as the speakers. My son used sheets of it for an engineering project. He and a lab partner built a boat using the corrugate, trash bags and duct tape. They traveled the length of an Olympic pool and back against the clock and set the new school record. It is seriously stiff.
