She-oak for enclosure?
 
anyone tried this for an enclosure?

would it be suitable?

basic density is 620 kg/m3 - 730 kg/m3

shrinkage before reconditioning are 4.5 and 1.2 per cent respectively, and after reconditioning 1.7 and 1.0 per cent respectively.

If you like the look, use it in veneer form, or as 'thick' veneer (ie cut with a bandsaw to 1/8" - 3mm - thickness) bonded to a stable medium like mdf.
Regardless of how stable a hardwood, or softwood, is supposed to be, there is still too much movement for an item like a speaker. That is why furniture is designed to accommodate movement in wide panels, which is detrimental to speaker cabinets.

Veneer suggestion
 
If you go the veneer route, have a look at (Australian) silky oak.
Cardwellia sublimis (sp?)

Beautiful!

Very cool looking. If you go the veneer route it needs to be thin, about 1/16", or you will get cracks. If you use solid make sure you think about the expansion across the grain. Top bottom and sides in solid grain all going the same way and the box grows front to back. Plywood front and back stay the same and don't force the box apart.

The sides of the briefcases are solid wood, but the top and base are veneered on both sides. So no probs.

i can get this in plywood form, is it still not suitable for 100% due to shrinkage?

Veneered plywood will be fine.

Speakers can be successfully built from solid. It is tricky thou and you need to know what you are doing.

Hopefully some of the guys who know will chime in (i'll ping Bernie for you)

Unfortunately this is one of those situations where if you have to ask the question you are not ready... but you have to ask to get to thet point...

Oak by itself is an open grain wood and it is prone to shrinkage. I have used American Oak for the facia of my kitchen cabinets and in hindsight think I made a mistake. May not even be suitable for veneer.
