I hope the OP will forgive me, but it seems this thread has already gone in bit of a different direction already. It would seem to me, despite being somewhat contrary to audiophile common sense; that flush to wall/corner mounted drivers (preferably flat, concentric and with 1st order crossovers) coupled with room correction might be most advantageous. Such flush mounting of drivers with room correction would negate the differences and overcorrection of the direct vs the reflected sound, as the time of sounds would be nearly identical.
As the room response would be in someways more predictable, some of the placement induced concerns might be built into the drivers response, further reducing the amount of room correction intrusion into the signal.
