Ok, I know I'll get at least one response out of this post, but since I have never built, and have not immediate plans to built, a speaker or subwoofer I still wanna know why MDF seems to be the choice of cabinetry materials, which is then covered in a veneer. Wouldn't it be easier to use solid wood? Is there something about the uniformity of the manufactured MDF over naturally grown choice wood products? Is it acoustical properties that MDF exhibits to be better than natural wood? Please enlighten this ignorant soul.
