@perceval . , weird that they would block...
They are only 3/8 inch thick, but I think @xrk971 has used 1/2 inch foam boards with paper skins before to good effect.
I wouldn't use it for a long term build, but a quick prototype?
And now you got me thinking... what if you laminate 2 together to get 3/4 inch board that a "constraining layer" of cork? That might be a stiff and non-resonant board...
Interested in any thoughts...

He used the gator boards for very small and curvy designs, like the Nautilus shaped one, and the Karlsonators, with smaller 3" drivers.
For bigger projects involving woofers, at least 1" of XPS foam. Plus, it will be a lot cheaper than that board, limited at 20"x30"
XPS I got here was 36"x 72"x 1" for about $6.

Looks like cork board used for making bulletin boards to pin stuff. Not sure if stiff enough (if there is paper under the cork then it should be). But combine this with paper faced foam core and it would look quite nice and have damping abilities.

@xrk971 ,
yeah - that was my initial guess. I'm gonna try to do a quick build with it. I am also interested in gluing two together to see if it acts as constraining layer dampening with significant improvement.
I'd kinda like to to have the cork on the outside for appearance and handling.
wrt cost: yeah, I agree with @perceval , big sheets of XPS are cheaper. But if it's a nicer build of a small speaker, might be worth the extra cost.

Sometimes I've read where the jokes on you and those protos sound better than the final box material. God's humor; just because one wouldnt think so.Get a quick fair estimate of what the final build will sound?
Oh, I did a cork laminate once on a pair of OB panels. They still ring some, but not as bad as plywood.
