I found an indication at another forum that a William Schaeffer Audio Design stand-mounted monitor was a rebadged and modified version of a Chinese-made Aurum Cantus speaker. So the same thing might apply to your floor-standing speaker. Perhaps you can find it among the models linked to on the left side of this page:
