downbearing

The Steinway tech at the store where I floor tune was in a quandry today 
regarding a new custom made 9 foot Steinway called the "Rhapsody", to 
celebrate Geiorge Gershwin's 100th anniversary. The problem: "Scotty, we 
need MORE power!" I tried it after it was tuned, and it sounded like a small 
verticle. I speculated that the soundboard had "pancaked" as a result of 
excessive downbearing, and he concurred! This is possible, since everything 
else was pretty much ruled out. Regulation is precise. How would one go 
about REDUCING the downbearing, and hopefully restore the proper/original 
crown to the SB? I have read that DB is determined BEFORE initial stringing. 
Could the nosebolts/plate need adjusting? I assume the first thing to 
confirm this hypothesis would be to use a DB gauge, but he did not have it 
with him at the store At the time. Just curious to hear your thoughts. 
thanks!
