7.2 Loudspeaker placement and positioning
When deploying Cyclone loudspeakers, it is important to
consider the speakers’ vertical position to maximise coverage
in the vertical axis. Horizontal loudspeaker dispersion figures
dictate the coverage of the loudspeaker, left to right, to the
-3 dB points. The same can be said for the vertical dispersion
figure, but when applied to a listening area, this figure dictates
the audience area coverage front to back.
Vertical dispersion is often overlooked or not assessed
properly, resulting in ineciently deployed loudspeaker
systems that require more fill loudspeakers than are necessary
to achieve required coverage. Following are some basic
guidelines when considering the vertical position of your
Cyclone loudspeaker.
With optimum vertical positioning and aiming applied the
loudspeaker system can be used at maximum eciency. With
a point source loudspeaker in this configuration the speaker
is placed 2m-4m from the ground, aimed half way to two thirds of the way back from the
audience area, as shown in figure 7.6. The applied aiming reduces unwanted reflections from
the ceiling and directs the highest energy concentration to the audience area requiring it most.
This is the most desirable position for the loudspeakers in this example.
