I think the original post was talking about running more than one surround per side, like a larger movie theater. If so, I would probably add another vote for "that's why people buy QSx surrounds, to get the same effect as a large room with lots of surround speakers".

Unless the room is really large I don't *think* multiple direct radiating surrounds would be as effective as a good set of multipole surrounds.
