the maximum listening area with best possible
imaging while keeping the center loudspeaker from
being too far away. This is a goal; in practice, there
is quite a bit of flexibility in the exact placement. If
possible, the left and right loudspeakers should
about as far apart as the width of the stage or
performance area.
The surround loudspeakers, if used in this
auditorium-type setup, should be high enough
above the audience to allow even coverage, but not
so high that excess delay or interference problems
are created.
Placement Alternatives
The setup shown in Figure 11 may be impractical
due to the design of the auditorium. Often the center
loudspeaker needs to be located more in line with
the left and right as shown in Figure 12. In this
case, the center loudspeaker is typically higher than
the left and right, which is actually beneficial since
the distance from it to the audience area is more
uniform. This arrangement can achieve excellent
results.
Figure 13 shows a more extreme example where a
thrust stage requires the center loudspeaker to be
placed closer to the central audience than the left
and right loudspeakers. Also, the left and right
loudspeakers are used largely for the purpose of
covering a difficult audience-area shape. In this
case the stage configuration and visual aspect of
the design need to be accommodated in the sound
system layout.
Despite the inability for the side loudspeakers to
cover the opposite side of the audience, this
arrangement can produce very good results. A large
percentage of the listeners in the central audience
area can hear excellent stereo sound staging.
Those at the sides will hear a shorter sound stage
but with a full mix. It is far better than using mono
sound.
Left and Right Loudspeakers
The placement of the left and right loudspeakers
defines the width of the front sound staging area.
Their placement can be determined as it would for a
two-loudspeaker stereo system. Generally, the axis
of each loudspeaker should be pointed toward the
center of the listening area, as shown in Figures 10
through 12; this will provide the best overall
coverage and frequency response for the
maximum-size optimum listening area. When
clusters are used, as shown in Figures 11 and 12,
the inner cluster components, each of which covers
the opposite side, can be set to a slightly higher
