There are several reasons why almost no companies in the world make a solid wood speaker.
1. It's incredibly difficult. Wood moves. All fine hardwood furniture is made with joints or joinery construction, to allow the wood to move, to expand and contract. If you want to get around this, you can glue up small strips of hardwoods, which minimizes the problem of expansion/contraction (Sonus Faber) or you make a small speaker out of small staves of hardwood like the very well made Diapson speakers mentioned in this thread.
2. There is no market for hardwood speakers, as audiophiles have been fooled into accepting cheap MDF or now, the new fad for aluminum and other enclosure shells which can be inexpensively CNC built. There is no skill in that type of construction in comparison to the skill of a master furniture maker or luthier, by the way.
3. Audiophiles have no experience with hardwood speakers, so they don't know what they are missing. Not a great place to start a marketing campaign.
My company (disclaimer) is probably the only company in the world making solid hardwood joinery structure loudspeakers. If there are any which I don't know about in current production, I would certainly like to learn about them.
