Figure 13 shows SPL mappings for a distributed system of two XT enclosures with a spacing of 3
meters. Interference now occurs lower in frequency and will tend to be masked by room
reverberation. Compared with the closely spaced (arrayed) system of Fig. 12, there is now improved
intelligibility at higher frequencies. Essentially, the key to successful distributed system design is
reducing the effects of audible interference.
