For instance, a 4 high ground-stack of W8S' will act like the top half of an 8 high
stack.
(Important: see safety note above)
Note that flexible floors may actually absorb sound at some frequencies so the
situation isn’t always so simple in practice.
Horizontal - 6dB coverage
The following table gives the approximate horizontal coverage angles of typical W8S
arrays - ignoring boundary effects.

With W8S' standing upright, flat fronted cluster coverage patterns will be confined to
one main lobe whose mid-bass crossover width is inversely proportional to the size of
the cluster as long as horizontal gaps are less than 500mm.
♦
Use wide arrays for long shots. Useful for long, narrow venues
♦
Use narrow arrays for short, wide shots
Horizontal Boundary effects
A solid wall near an array will act as a reflector. This will cause a horizontal array to
perform as if it were twice as wide, giving a useful low frequency boost accompanied
by a narrower, more complex polar response.
