system corresponding to the “works” case shown in Figure 23)
Figure 22 shows SPL mappings for a distributed system of two MTD enclosures with a spacing of 3
meters. Interference now occurs lower in frequency and tends to be masked by room reverberation.
Compared with the closely spaced (arrayed) system of Fig. 21, there is now improved intelligibility at
higher frequencies. Essentially, the key to successful distributed system design is reducing the effects
of audible interference.
