If mdf isn t available and you need to look for another option the baltic birch plywood is the next best thing you can get. As far as i could tell when using it it had about the same strength as mdf. And birch will always be stiffer than both of those and lighter at the same time. Amongst hardcore diy speaker builders baltic birch is considered the best plywood.

Baltic birch s core is unlike traditional plywood you may be used to seeing. It s a recipe that results in a void free core with a number of advantages which is why in the u s. The layers of inner plies are about 1 mm thick solid birch veneer cross banded and laminated with strong adhesive. I ve built horn loaded speakers using 1 2 baltic birch for the inner box then covered it with solid wood overbox and silicone between the 2 layers to allow some wood movement.

Baltic birch plywood is often sold as void free plywood though some users have encountered small voids in these products. The mdf is more prone to mold and mildew not an issue if you seal with an oil based paint though and the dust particles are smaller than the birch making it more prone to inhalation while working with it. You can build speakers with whatever you like. Be sure to ask specifically for void free plywood if this is what you are looking for.

Another great thing about birch is it will always have less saw dust. I ve also done some where the front face has a stepped dado around the outside edge which mates into another dado around the inside faces of the sides which were mitered. The birch will be more expensive but will last longer in the big picture. Hope this helps aric.

It is void free 13 layer 3 4 often in 5 x 5 sheets though sometimes 4 x 8.
