Same idea but with the lopass at the bottom left and hipass at the top 
right - the "Z" shape gets flipped over and becomes a stylized "S" 
shape.  I think someone suggested that the panel layout would be more 
intuitive with the frequencies going low to high from the bottom to 
the top of the panel?
