Unicon, I would not argue that our ears just don’t care as much about amplitude as they do about phase; I have been pitching it myself. However, I think you do properly interpret the need of the “exact parallel sound from drivers”. The parallelness of the axis is necessary not because it create the “parallel sound” but because drivers have dimensions. Because the diameter of the drivers the arrival between the side and the middle of the cone is different. If the driver is faced to microphone/listener with peripherals of the cone equidistant from the sweat spot then it is not the problem. Then you moved 2m back - the peripherals of the cone will be also equally distant from you. Now pretend that you have 2-5 drivers and unless you would like to locate them in the curve looking directly at you (that has a lot of own problems) then you would want to introduce a permanent off-axis error. The off-axis angle is not a big deal but what is important in my view in context of multi-way system is that the off-axis would be constant for all driver and do not wary with distance.
