    Directivity is an important issue because it affects the frequency balance of sound a listener hears, and also the interaction of the speaker system with the room and its contents.

    Clearly then, sensitivity does not correlate precisely with efficiency, as it also depends on the Directivity of the driver being tested and the acoustic environment in front of the actual loudspeaker.

    Horn loudspeakers use a shaped waveguide in front of or behind the driver to increase the Directivity of the loudspeaker and to transform a small diameter, high pressure condition at the driver cone surface to a large diameter, low pressure condition at the mouth of the horn.

    The Directivity of a dipole is a figure 8 shape with maximum output along a vector that connects the two sources and minimums to the sides when the observing point is equidistant from the two sources, where the sum of the positive and negative waves cancel each other.

    18

    A mathematical expression for the Directivity of a complex shape, based on modeling combinations of point sources, is usually not possible, but in the far field, the Directivity of a loudspeaker with a circular diaphragm is close to that of a flat circular piston, so it can be used as an illustrative simplification for discussion.
