3.0 Designing an EVA Array (cont’)
3.42 A Five-Module Array Example
Figure 9 shows another, five-module array in an 80-ft-deep venue with the front row five ft from the ar-
ray and whose floor begins to rise about halfway back. The three frequencies not only track very well but
nearly all of the venue is within ±3 dB front to back. This desirable situation is helped by not only the 3-dB
attenuation of the top module but also by the array being longer than the three-module examples above
(4.4 ft versus 7.3 ft).

front-to-back, but also fall mostly within the desired ±3 dB
