Is cast concrete best with box speakers to get the best sound quality?

Mark and Daniel! That was it. They make speakers out of what's essentially formica and CAM process granite.
There're a few speaker manufacturers who use stone or concrete of some sort:

And vintage Gemma speakers from the 80's were made from marble

And I believe there's another one with two last names as the brand - like "__________ & ___________", but all I can think of is Harry & David, which isn't it.
