Again, a flexible side wall may absorb sound at certain low frequencies. Boundaries
should always be treated with caution.
Spacing
It is possible to space out W8S' to provide a larger frontal area with fewer units but
care must be taken to avoid irregular coverage at higher, mid-bass frequencies.
The following formula gives the pressure ratio (wrt the on-axis pressure) for
any off-axis angle of a regularly spaced linear array:
Far field polar patterns can be quite complicated - even for a simple pair of
subwoofers driven in unison.
