You can buy special bendy plywood in various thicknesses.

I've also found a plywood manufacturer where you can specify what your ply is made of including sound deadening layers which is usually used for boat building.
Never even dared to ask for prices or minimum order size though.

If I'm not mistaken, 10 tons applied to a 4' x 8' sheet is a bit over 4 psi.

A friend who works at a supplier for custom marine panels brought me some leftovers, enough for two modest baffles.

That looks fantastic for our application- make a frame for the interior box and let the outside panels float (so no connection to each other, you'd see the cork layer)

That's the plan, badman- driver mounted to the outside layer of ply, and the cork layer doubles as decorative.

If you can, I'd try to mount it to the inside and shape the wood in front- the idea being the excitation excites the inner panel and has to pass through the CLD to emit panel resonance into the room.
