Always interesting when some of this stuff comes up. Dense wood, and initial MC play a role in the end velocity of sound through the wood, if we are too believe some research. A study in Finland at the Tampere University of Technology also couples opened so-called "ring" pores that come with age with an increase in sound velocity conduction. Who knows, but it seems obvious (to me anyways) that there a good deal unanswered questions about the acoustics of wood.
