Nothing from a big box retail store is likely to give good results. I've never seen baltic bitch at any of them, and frankly, I've never seen them stock any plywood I would be comfortable using to make loudspeakers. 18mm baltic birch has 13 plies and is very strong. The plywood you often find with 5 to 7 plies is terrible for making speakers. You'd be better off with chip board than that stuff.
