3.2 DISTRIBUTED SOUND REINFORCEMENT
Distributed sound reinforcement using P Series enclosures can provide even SPL coverage and
frequency response while reducing audible interference effects. For distributed installation, the
optimum spacing between enclosures will depend on the coverage angle of the individual enclosure
(100 degrees for 108P, 90 degrees for 112P) and the throw distance to the audience listening plane.
In general, the goal is to separate P Series enclosures so that the -6 dB coverage angle of one
enclosure is aligned with the main 0 degree axis of the other enclosure (and vice versa) at the listening
plane of the audience. This is termed centre-to-centre alignment and is illustrated in Figure 15.
