I looked around my local Home Depot and spotted some decent looking plywoods. Upon curosry inspection, the surfaces looked very clear and I did not see any voids around the perimeter. AS I recall, the 3/4" stock was five or six plys. Would one of these also be a good choice for speaker cabinets, or should I continue to seek out Baltic Birch from a specialty supplier?3/4" x 4' x 8' Baltic Plywood - $49.88/sheet
