One of the best bookshelf speakers I've ever heard was constructed of bamboo plywood but, because it was a while ago, I don't remember the manufacturer. It may have been Canalis but that's just a guess. I don't know if the sound quality of those speakers had much or anything to do with the bamboo construction but I'm preparing to build enclosures for single full range drivers to be used in a small listening area and, because I don't like working with MDF, I'm trying to decide whether to try plain hardwood, birch plywood or bamboo plywood. I've done a little shopping and have found that the several choices in 3/4 inch "carbonized" bamboo plywood are not sold in many of the local outlets and that it is very much more expensive than other wood.
This thread has been helpful in that regard but I would appreciate comments regarding the use of bamboo. I admit that I'm leaning toward bamboo partly because it's different and looks neat.
