A directivity map is a plot of the radiated directivity pattern of a loudspeaker. It shows frequency on the x-axis
(horizontal) and the off-axis radiation angle on the y-axis (vertical). The SPL is denoted as color variation. It is normal-
ized to the on-axis response. A horizontal slice through the map will yield the normalized off-axis response. A vertical
slice through the map will yield the values for a conventional polar plot.
