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 loudspeaker Open space projection (throw)
vs peak spl for a
loudspeaker pair
97dB 103dB 109dB
AQ5 11.2m 5.6m 2.8m
AQ6 10m 5m 2.5m
AQ8 18m 9m 4.5m
AQ10 36m 18m 9m
AQ12 40m 20m 10m
AQ15 56m 28m 14m

2) Choose the loudspeaker-to-loudspeaker spacing for smooth coverage. This spacing will
depend on the distance to the nearest listener. Loudspeakers spaced too far apart may
leave coverage gaps.
The following chart will help you to work out loudspeaker-to-loudspeaker spacing for very
smooth coverage as a function of the minimum listener distance.
