Distributed Aq Series Systems - Martin Audio AQ Series User Manual

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:

Open space projection (throw) vs peak sound pressure level
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.
