Repositioning woofers near the rotation axis improves low-frequency measurement splicing accuracy

Evidence

Relocating the woofers of tall loudspeakers to be closer to the axis of rotation can yield more precise data at low frequencies, which then can be spliced to the mid-/high-frequency data. Ideally, every distinctive configuration of loudspeaker would need to have a reference curve measured on a tower, or ground-plane equivalent, and I know of one manufacturer that takes the trouble to do this. — Toole, Floyd E, Sound reproduction- the acoustics and…, 169
