The use of real wood is actually a bad idea as wood never dies. Wood is constantly moving with climate changes it absorbs moisture and the dries causing it to expand and contract. There in lies the problem, it causes the surface to develope 'checks' and cracks and offers an inconsistancy in resonance and vibration control. MDF has proven to be the best as it can be face glued to any thickness then machined and contoured easily as it has no grain. Veneer is a great exterior cover as it is thin enough to move with no difficulty and to easily be book matched. So in summary, the use of solid wood offers no advantage where the veneer covered MDF or particla board in cheaper speakers is better for long term stability of the cabinet.
