I would like to build some rustic looking speaker cabinets to match some cabin furniture.

From what I have read, building cabinets from solid wood is a no-no because of vibrations and changes in humidity.

If I build the cabinets out of MDF and then put 1x2 planks of knotty pine or some plywood with a knotty pine veneer over the MDF, will I still get the undesired effects of the wood?

Are these solid wood cabinet issues as bad as they say? It seems like there are a lot of instruments made from wood... How bad can it be?

Any thoughts or suggestions?
