When sound sources are stacked vertically, there are interactions between them that change with movement along the vertical plane. Their positions are as important, if not more so, than the vertical coverage patterns of the individual sources, because as path lengths change, so change the phase relationships between sound sources. Ultimately, these relationships set the shape of the forward lobe and the positions of vertical nulls.
