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 resonances. Tilt angles should be set so that the loudspeaker’s maximum output (usually on-axis of the loudspeaker centre) is aimed at

8. Horizontal aiming Horizontal angles should be set so that the loudspeaker’s main horizontal coverage is directed towards the main listening area. Avoid excessive 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 AQ6, AQ8, AQ10, AQ12, AQ15 aiming AQ5 placement For the cleanest coverage, AQ5 dual-driver loudspeakers are best kept away from tight

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 results as long as the following simple steps are taken in the system design process: 1) Choose the AQ Series loudspeaker to suit the maximum distance to be covered. The chart below indicates the maximum distance covered by AQ Series loudspeaker pairs: AQ Series lou

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 6m = 5.04m for very smooth coverage. The above calculations will provide very smooth coverage with approximately 3dB mid- band sound pre
