Yes.... Well, the argument would almost seem to hold water = for a rib crowned board. However, (and sticking to the "holding water" = analogy <grin>), saying that a SB's loss of efficiency is proportional = to its loss in area is a bit like saying a rusted water pipe's loss of = ability to hold pressure is proportional to its loss of wall surface = area. Nonsense! It's a lot more complicated than that. Try making the = board twice as big and drilling out half of the wood (i.e. a Swiss = cheese soundboard). It should be just as efficient according to their = argument, right? Wrong! It would be so acoustically "leaky" that it = wouldn't radiate much power. However, all things considered, I suspect the total loss of power in a = cracked RC soundboard isn't all that significant, nonsensical acoustical = arguments notwithstanding.
