The coverage patterns for a distributed wall mount system are similar to ceiling mount designs,
except only a single row is used in the pattern. Because of the typically larger potential speaker-
to-listener distance, only edge-to-edge and tighter spacing patterns should be used to provide
adequate intelligibility.
Care must be taken not to overextend the penetration into the room that can be expected from a
wall mount speaker. Rooms greater than 20 feet wide should not be treated with a single wall of
speakers. When designing a system where the opposite wall is greater than 15 feet away from the
speaker, minimum overlap or full overlap patterns should be selected. See the figure below for
typical wall mount speaker coverage pattern examples:
