Page 15: Loudspeaker Placement And Positioning
6 System design 6.2 Loudspeaker placement and positioning When deploying ArcM 12, 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. - Page 16 Figure 6.8: Multi point loudspeaker arrangement In the horizontal plane rotate the ArcM 12 toward the audience area at an angle such that the centre line of the dispersion from each loudspeaker meets about two thirds of the way towards the rear of the audience area.
- Page 17 6 System design Avoid directing the ArcM 12 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.
