Polycarbonate is very sensitive to chemicals. Most polycarbonate parts are painted or "hard coated" like automotive headlights. You have to even be careful with the paint - solvents swell into polycarbonate, cause the plastic to crack, then the solvent evaporates out to leave an ugly bond. Be careful of the adhesives you use. Polyurethane adhesives tend to work well - especially 2k polyurethanes but check the adhesive manufacturers recommendation.
For acrylic, there are "solvent free" or foam safe epoxies that will not cause hazing on acrylics.
A speaker enclosure is supposed to be inert so it does not vibrate or resonate. Your plexiglas is so thin that it will vibrate and resonate which will color the sounds and sound odd.

I'm guessing try amplitude will be quite low - like a little museum display intended to just be heard by 1-3 people looking at the collectibles. It won't sound too bad. On the other hand, I would likely pull some narrow-format speakers from a flat-screen TV and tuck them on the bottom edge so they are not so visible.

Point taken. Please understand, however, that in this case, a low-fidelity recording from a low-fidelity recording of a 1940s radio broadcast (which I processed with whatever noise reduction filters (Audacity) that I could find need only be intelligible, which it is - that is not a problem. In fact, the remaining hisses and clicks are rather charming

Yep. It sounds *very* good, for what it is, using either of the speakers that I showed in the pics. I have played for a number of folks and all like it and some give me the usual...oh you should sell that.... None, however, say...hey make me one and I will make two enclosures for you....Nooooooooooo can't say that (and I am just kidding, it is not an offer).
