I've head them in many, mostly modest systems, though not in some time. The reason I mentioned them was; they were inexpensive speakers, that didn't take up too much space, that could be driven by a cheap receiver, and still fill a large space with nearly full range music without completely embarrassing themselves. Very few others could do that, without costing significantly more (percentage wise). Not my cup of tea, but could work for some others with a large space, on a tight budget, that didn't want overly large boxes dominating the room, and not interested in too much fussing.
