Undersized arrays
The illustration at the top of the following page shows a small, typically-curved array being
deployed to cover 100 m.
Figure A.8: Flown and curved 6-cabinet (1.71 m) Arcline 8 array – too short for 100 m - showing coverage level vs distance
(red = 315 Hz oct, blue = 3.15 kHz oct)
Equalising the high-mid/HF to match the low-mid would defeat the object of using a line
array, of course.
Adequately-sized arrays
Figure A.10 shows a 24-cabinet array that is more suitable for 100 m coverage:
Flying and curving the array can move the coverage peak out a few more metres but the array
still acts like a point source.
Any attempt to apply low-mid equalisation to the cabinets covering the front 30 m would be
futile as such equalisation simply makes the array act even more like an LF point source
Figure A.9: 6-cabinet (1.71m) Arcline 8 array with futile attempt at bottom cabinet low-mid equalisation
(red = 315 Hz oct, blue = 3.15 kHz oct)
