Multiresolution Line Array

A simpler geometry for the line-array case is parallel strips covering different bands (Fig.10).

Figure 10: Example multiresolution line array implemented using strips of drivers at different sizes.

Of course, the drivers do not have to be circular, and some tweeter geometries are non-circular. Also, circular drivers can drive the base of horns having rectangular exit apertures that tessellate a linear or planar region.
