David Love writes: Well this is an important point. Why doesn't compressing the panel make it stiffer? It seems like it must? Even if compression and stiffness are not synonymous in this discussion, then the question is does compression itself change the physical and acoustical properties of the panel? David Love davidlovepianos@comcast.net It does. The strength and stiffness of wood is directly proportional to density. Its just that the point made was a misdirect. The important bit is that a CC board relies much more on compression in the panel for the assemblies overall stiffness. RicB
