The following delay line taps would be required for the above system:
t0 = 0ms
t1 = 0.83mS
t2 = 1.66mS
t3 = 2.49mS
t4 = 3.32mS
t5 = 4.15mS
t6 = 4.98mS

It is possible to apply electronic shaping to horizontal arrays. For instance, it is common to use curved main
clusters for smooth mid and high frequency coverage. Ground-based subwoofer arrays should follow the
same curvature to maintain mid-bass crossover coherence but this is often difficult due to flat-fronted stage
structures.
The following illustration shows an example of a flat-fronted horizontal array electronically splayed to
emulate the grey-out example shown.
