CEMENT SPEAKERS - anyone remember these?

In the late 80s when I went shopping for speakers in San Diego, I visited several of the high-end salons. One of the shops had a set of cement speakers from a company if I remember correctly was called "Ronus". They were very unusual - towers made completely of finished cement which he said you could paint any color you wanted to. Anyone recall these???
dac, was ir rauna*?
Rauna made several models, well-reviewed, but there's a thread on AA suggesting they are coming out soon with a new version of the Rauna Tyr. My neighbor across the street sold an old pair in a garage sale last year. Pretty good speaker for the money.
Rauna, yeah, that could be it. They were pretty sweet sounding.
