Specifications

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.

W8S' Wide Horizontal coverage

(standing upright) 40Hz 80Hz 160Hz

3 Wide Wide 98º

4 Wide Wide 69º

8 Wide 69º 33º

16 69º 33º 16º

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.
