Ceiling Speaker Spacing And Coverage
Note that increasing volume results in the speaker being louder in its covered area, but does not increase the area covered by the
speaker.
The design goal of speaker placement is to allow people to hear just about the same volume from anywhere in the room. The goal is
accomplished with a symmetrical layout of the ceiling speakers which achieves edge-to-edge area coverage, as shown in Figure 9.

Typical Ceiling Speaker Layout
B. SA-B4 Surface Wall Mount Speakers:
Surface wall mounted speakers are used where it is not practical to mount ceiling speakers. Forward sound projection and spacing are
important, and Table 3 provides a guide line.
