I've never used it, but I can tell you that I've seen a lot of plywoods that aren't suitable for speaker building. Most aren't, actually. The thing to watch out for is internal voids between plies that have debris which causes a buzzing sound. Worse yet, loosely attached fibers in an internal void that break off after a few hundred hours of playing time, so the speaker develops a buzz long after it was built. That can be a real disappointment.
It's hard to say whether a wood panel has this kind of defect just by looking at it. It's also hard to learn whether a new product will be good or bad in this respect until you've had a lot of experience with it. In most cases, some panels are fine, so the whole deal is a crap-shoot. The only plywood I've had consistently good luck with is baltic birch. If you try this bamboo product, please report back and let us know how it works out for you.
