where waves entering a grid first will form a large number of point sources to later recombine into a wave front parallel with the grid? As a corollary at a sufficient distance from the flat source the wave front will be the same as the wave front from a distant point source. The transformation depends on a number of factors, as you listed most of them. So you are right even flat speakers like Maggies and Apogees act as virtual line sources, just not as well as Soundlabs.
