In these examples “wide” means that there are no coverage nulls within the forward 180º at mid-bass crossover frequencies. Wide coverage arrays have significant output beyond 180º making them more prone to room colouration.

“Narrow” means that coverage will drop significantly before 180º coverage is reached at the mid-bass crossover frequency.

General rules:

The larger the array the more directional it becomes

A larger, directional system will be less affected by the room

We get a 6dB far field sound pressure boost every time we double the number of cabinets.

Stacking safety!

Stacked WLX or WLXGS subwoofers should always be blocked, strapped and anchored from above by a qualified rigger.
