Why do we need crown?

[Erwinspiano at aol.com]

Hi RIc
   Not so  with the reverse crowned board.  I have  worked on my share of 
intentional reverse crowners & although the board  is under a positive 
downbearing load the pins do not have any more trouble  staying seated than the 
conventional system. The board is under tension but in  my expereince with less 
adverse affects than the boards built ....the other  way
  The whole issue of crown is that is needed or certainly desirable to  
create varying amounts of impedance by compressing the soundboard, which is a  
spring  thereby making it more reactive to vibration & thus move more  air,sound 
etc. but we've certainly covered this before.  right?

Hi  Don.

Then too... in the grand it seems like we have trouble  enough as it is 
keeping strings seated to the bridge. Downbearing  or no... with the 
panel countercurved as it were it would seem to me that  the strings 
would find it even easier to become  unseated.

Cheers
RicB
