A typical arena gain set-up may be as follows:
Main Longthrow section -12dB to -6dB
Double W8C midfield section -6dB to 0dB
W8C downfills -4dB to 0dB
2.9.3 Adding Longthrow elements to W8C/W8CS clusters
Wavefront Longthrow elements may be added to conventional W8C/CS clusters for
larger venues, to improve overall sound projection to, for example, upper rear seats.
Note that when just a few Wavefront Longthrow elements are used to supplement a
large W8C system, high-mid/high W8CTs may be used without low-mid W8CMs as
low-mid energy is provided by adjacent W8C low-mid sections.

A simplified maximum horizontal coverage calculation is:
27.5º (left ½ W8C/W8CT) + 15º + 15º + 27.5º (right ½ W8C/W8CT) = 85º
A simplified maximum vertical coverage calculation is:
3.75º (top ½ W8CT) + 8º + 20º + 20º + 15º (bottom ½ W8C) = 66.75º
