DIY speakers of solid/reclaimed wood?


This popped up on FB today and got me wondering if solid wood would be a bad choice for speaker cabinets.Seems it would be unstable and tend to warp.They are pretty little things.I'm sure interior designers love them:)

That is a small speaker and the wood is thick enough with enough structure that warping won't be a problem.  A cabinet that small with front and backs attached will be fairly inert. I've built tons of speakers and even though I really don't use solid woods.  I could, but would properly brace everything to keep down issues that arise with solid woods. 
Huh!Aren't those gorgeous!?I've heard of the brand but wrongly assumed they were veneered.

I'd feel as if something's watching me every time I come into whatever room they're in.
