> The point is to isolate the atmospheric environment of the soundboard back > from that of the room atmosphere. Kind of like getting one side of a thick glass cold and the other side hot. Not sure I like that so much. Stress on one side and no stress on the other. Not sure I like that so much either. Take a board and seal one side with poly finish and see how stable it would be with changes in humidity. Not sure I like that so much. Not sure... Newton
