You might want to try "Partsexpress": Go to their site, find "Speaker Building" at the top of the page, and look at "Laminates" to the right in "Parts and acc." They have quite a variety of vinyl laminates that may be quite close to Axiom finishes.

They sell it in 2ft by 10ft rolls for about $15.

They also have a pretty good forum that may be able to answer some questions about whether this approach may be appropriatefor your application.
