The complete installation should be checked and approved by a qualified structural engineer and a qualified electrical safety consultant before being signed off. 7. Vertical aiming AQ Series loudspeakers should be mounted above head height – high enough to clear peoples’ heads for clean coverage but low enough to avoid over-exciting room resona[...]

8. Horizontal aiming Horizontal angles should be set so that the loudspeaker’s main horizontal coverage is directed towards the main listening area. Avoid exce ssive reflections from nearby side walls. The following example shows AQ Series loudspeakers with 80 - 90 ° horizontal dispersion (all except AQ5) toed in 40 - 45° from the side walls AQ[...]

9. Distributed AQ Series systems AQ Series loudspeakers are ideal for distributed sound systems in places like sports stadium concourses, exhibition centre walkways etc… Distributed systems can provide superb sonic result s as long as the following simple steps are taken in the system design process: 1) Choose the AQ Series loudspeaker to suit th[...]

Example 1: Horizontally distributed AQ5 loudspeakers are required to cover smoothly from a minimum listener distance of 3m . The spacing required is 1.73 x 3m = 5.19m for very smooth coverage. Example 2: Horizontally distributed AQ12 loudspeakers are required to cover smoothly from a minimum listener distance of 6m . The spacing required is 0.84 x [...]
