Common tall loudspeakers are not true line sources

Evidence

For a contrast, let us examine the behavior of true line sources. I say “true” because they are rare. Tall loudspeakers are common, but these are multiway systems, not a linear array of full-range transducers. Even truncated line sources behave very differently, and much worse, as will be seen.
