Figure 7.10: Incorrect loudspeaker placement
Figure 7.11: Incorrect loudspeaker placement
Figure 7.11 shows the loudspeaker vertical position is optimal for the audience area but the
user hasn’t applied an aiming angle. In this case, a large portion of energy is directed at the
ceiling that could result in reduced intelligibility and unwanted room acoustic characteristics.
The shallow angle of attack will also induce refraction issues on a hot dance floor, leading to
reduced HF penetration at mid and far distances, again reducing intelligibility and coherence.
In figure 7.10 the loudspeakers vertical positioning is too low for the audience area. Mid
and high range frequencies are absorbed by the first two rows of people, resulting in poor
coverage and potential acoustic issues from room reflections.
Audience
Stage
Avoid directing the Cyclone loudspeakers straight forward. This will result in a proportion of the
power being directed towards the walls, creating possible reflective issues, as well as causing a
gap in coverage at the centre of the audience area.
