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.
