I can’t see a way that the doors are available, as there is no way to readily replace them. One of mine had gotten stuck a few years back, and I tried to figure out how to access the mechanism. That simply didn’t appear possible without going in a direction which would have caused more damage than it would have cured. I did finally discover that brute force was the answer, at least in my case.

It will probably be your best bet to source a used one and, if needed, add the speaker kit to it.
