DIY speakers of solid/reclaimed wood?

Huh!Aren't those gorgeous!?I've heard of the brand but wrongly assumed they were veneered.

That's what I thought.I've worked a bit with solid wood on other types of projects and have had to ensure that it has a little room to move to avoid splitting and buckling.Daedalus found a way around that somehow?

Ok,well now I need to find out what methods are used to keep the wooden instruments and the daedalus speakers in perfect condition.
I do know for a fact that very old furniture and woodwork does require regular maintainence and repair. 

After googling around a bit I found out the daedalus speakers are not 100%solid wood,other materials are employed.The old wooden instruments had to have been carefully stored,maintained,and occasionally repaired.The secret to the pieces of wood used is the way it is slowly and completely dried then sealed completely.Darn,I actually had to think and learn something new today:)
