There are very few woods that actually resonate. Basically EVERYTHING about wood avoids resonances. The inconsistencies in its density, cellular structure, and grain all serve to internally dampen a piece of wood. Dampened things dont resonate.
MDF is used because its actually flat. Cut boards are almost never flat, which makes building a tight enclosure virtually impossible. You can find small speakers and high frequency drivers mounted in solid wood cabinets.
|We have some stock woodie headphones, and the ones that came with wood stock, are made of very hard woods, almost non resonant, like the case of the R-10 that is made from the heart of zelcova, or mahogany in the case of Grado, etc..
The shell of the D5000 is mahogany. I would argue against calling mahogany almost non resonant, it is VERY non resonant. plastics depend on the plastic and how its formed. metals: most are resonant enough to make a functional bell out of.
the beauty with a "hybrid design" using BOTH metals and wood is that the wood dampens the ringing of the metal, and a little metal gives the wood exceptional strength. i'd say its QUITE cool.
