The Youtube channel "Real World Audio" has an interesting bit about real wood "live" speakers and their potential benefits. "Live and Dead Cabinets Both Alter the sound" is the Youtube title.
The standard line is that real wood cabinets generate too much resonance - much more so than plywood or MDF. However, the author argues that real wood speaker cabinets can be very useful for producing the tone of wooden musical instruments if tuned properly.
Some years back I was scouring Ebay for one of those CF series Klipsch speakers designed by a young Ray Delgado, and one of the listings included a photo of the inside where it was clear that the cabinet was made of solid quartersawn white oak - a thing not often seen even in the early 1990"s. The CF series was not generally successful because it "didn't sound like Klipsch." My question is still "what did it sound like?"
