Paul Klipsch used false corners in his living room. I built a pair and they worked quite well
Of course it wuill work, as the false corners will provide the necessary mouth to the folded horn for them to perform properly (of course room modes will be different so it won't sound exactly the same as in the room corners but it will work - imaging can be better too).
Tiger, ever notice that any sound science gets quickly refuted on these forums...
