After searching for 2 years I found a dual density fiberboard. Like a hdf or x2 the density of mdf. The subwoofer box builders dream. I can sell and ship 3ftx3ft sheets in con us for 40 bucks a sheet. I don't have pics but can if anyone is interested but it looks just like mdf same thickness 3\4inch but very very smooth finish and you can definatley tell it is much more rigid.

not sure on all of that? I would have to cut a sheet of mdf and a small piece of the dual density to see the difference. I know it took two people to load the stuff one was me and it did seem much heavier than MDF. I will post later tonight when I can.
