All laminated 4/4 Hard Maple. It is roughly 3 3/4" thick, 24"x28". It's meant to be a base for a 150lbs. subwoofer to sit on. Apparently it isolates the sound and makes it cleaner. I don't know, I just build what they pay for.:dontknow: This is after first coat of Waterlox. Will be spending the next week applying more coats. And now I have posted pictures as promised.
