The point is that the wood will selectively absorb particular frequencies more than others. In Warmfire's sandwich there is a lot of wood. I am pointing to instrument makers because they are aware of which woods have what tonal performance.

The finish is important if there much surface, the surface is large in the sandwich structure. So the kind of seal makes a difference.

In the sandwich structure there is double the amount of wood than a single layer frame. The edges of the wood are free and will act like reed resonators - sort of like Josh's description - the edges of the sandwich are a long tuning fork.

Therefore, one should expect that the wood used would contribute substantially to the overall sound particularly as it would absorb at particular frequencies, and throw off other particular frequencies.
