Without the high compression levels of the 4%MC assembly, the RC&S wouldn't have the compression damage and accelerated aging. Starting with 6%MC, the compression levels, and hence the panel damage, don't reach the same level of severity. And what panel damage might accrue from whatever compression set the panel incurs, the ribs are still supporting crown and bearing and keeping the assembly functional. >I hear > what you're saying about wood, but if we're going to be consistent, why > should there be accelerated aging on any type of panel if it's kept in a > relatively stabile environment. /* That's the problem in the real world, isn't it? A relatively stable environment is easy to spec, but unlikely to be found in most venues. If you're going to build something that is to survive and function in the real world, you can't factor real world conditions out of the design equation. > */I'm just trying to get a sense of that interchange of stiffness from > compression verse rib support.

Tonally, you have to find what produces what you want to hear, regardless of the structural and longevity price. Then you have to consider the climate extremes the whole mess will be subjected to and decide what will best meet your performance criteria for what you consider an adequate amount of time under the abusive conditions in which it will be expected to perform, and build it. Piece of cake... Ron N
