6 System design
6.1 System design principles
Air 8 loudspeakers can be arrayed as a single pair facing forward to provide a wide stereo image.
Figure 6.1: Air 8 loudspeakers single pair arrangement
For applications requiring wide horizontal coverage, use two Air 8 loudspeakers in pairs, angled at about 40°.
40° 40° 40° 40°
Figure 6.2: Air 8 loudspeaker dual pair arrangement
For permanent installation, it is recommended to fly Air 8 loudspeakers for more even coverage. This also allows co-located low frequency enclosures in a single block, increasing sensitivity and providing more consistent bass coverage.
Air 8 User Guide V1.0

6 System design
6.2 Loudspeaker placement and positioning
When deploying Air 8 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 inefficiently 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 Air 8 loudspeaker.
Figure 6.4a: Vertical dispersion (side view)
Figure 6.4b: Horizontal dispersion (top view)
With optimum vertical positioning and aiming applied the loudspeaker system can be used at maximum efficiency. 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 6.5. 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.
Figure 6.5: Correct loudspeaker placement
Air 8 User Guide V1.0
Page 14
6 System design
A multi-point loudspeaker system in a club/bar environment can be very pleasing for the listener. However, it’s important that the processes applied to previous examples are still implemented. In figure 6.6 you can see the loudspeakers have been positioned and aimed optimally. When deploying a multi-point loudspeaker system, extra consideration must be taken to counter unwanted room effects. Careful positioning and aiming of loudspeakers will minimise room effects, while maintaining even coverage throughout the audience area.
Figure 6.6: Multi point loudspeaker arrangement
In the horizontal plane rotate the Air 8 loudspeakers 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. This will help provide a wider coverage and result in more of the power being used usefully.
Audience
Stage
Figure 6.7: Correct horizontal dispersion
Air 8 User Guide V1.0
Page 15
6 System design
Avoid directing the Air 8 loudspeaker 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.
Audience
Stage
Figure 6.8: Incorrect horizontal dispersion
In figure 6.9 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.
Figure 6.9: Incorrect loudspeaker placement
Figure 6.10 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.

7 Mounting
Tools required
• 4 mm Allen key
7.1 Installation safety
To avoid mechanical hazards, please note the following:
• Safety regulations vary in different regions. Full compliance with those regulations must be your priority
• Rigging must only be undertaken by fully-qualified and experienced riggers who understand local regulations
• This may include consulting a structural engineer before installation of wall brackets
• Remember that all personnel have a duty of care to themselves, to their assistants, to the venue staff and to the public
• Before lifting any part of the system above head height, check the whole rig for loose tools or other items that may fall and cause injury
• Do not use a telephone (even if hands-free) while rigging. Always concentrate fully on the rigging operation
• Do not rig equipment that is worn, damaged, corroded, mishandled or over-stressed in any way
• Use only Void-approved mounting equipment and accessories
