If the speaker's radiation pattern is too wide for the audience, there is over-coverage as

shown in Figure 3a. In these situations, sound radiates to areas other than the audience where

it reflects off of surfaces and arrives at the ears of the listeners as reverberation, which causes

degradation in clarity and intelligibility.

Figure 3a. The effect of choosing a speaker with a radiation pattern

wider than the audience is shown. Sound striking surfaces other than

the audience causes unwanted reverberation and reduced musical

clarity and speech intelligibility.

If, on the other hand, the speaker's radiation pattern is too narrow for the audience, as

shown in Figure 3b, people outside the main beam will hear a serious degradation in tonal

balance, level and clarity.
