This is a cautionary tale about the risk of drawing wrong conclusions when being unable to — self‑check — one's own data interpretation. Whereby turning analyzer usage into a video game. And treating the on‑screen data as gospel with blind faith. To paraphrase Jamie Anderson:

White noise is a random signal having equal intensity at all frequencies. And refers to a — statistical model — for signals, as opposed to any specific signal. In discrete time, white noise is a signal whose samples are regarded as a sequence of — serially uncorrelated — random variables with zero mean and finite variance. Where — any — zero‑mean distribution of values (without DC component) is possible.

This article explores reasons for considering frequency shading — as opposed to gain shading — to optimize the tonal uniformity of line arrays.

Figure 1This may come as a shock — coming from the author of the Subwoofer Array Designer — but over the years I have grown an increasing dislike for horizontal subwoofer arrays.
The only thing they really have got going for them, is their left‑to‑right spatial uniformity — provided — they do not fall victim to one honest mistake.
