   No, it can not be said like that. It is not a rigid material, so it becomes   
   very much a matter of how the box is braced. The "best material" is quite   
   likely to be a composite structure.   
      
   Example: Briggs "Loudspeakers" has as an example of a good construction   
   concept a corner bass reflex box built of bricks and mortar with a 12"   
   loudspeaker mounted on a plywood panel for ease of fitting. It is many ears   
   ago I borrowed the book from Duelund and read it, but I tend to think that   
   Briggs expressed preference for bricks and mortar over concrete.
