A mid-frequency off-axis sag is a common audible attribute of two-way loudspeakers.
Evidence
Loudspeaker 1 has a sagging off-axis output in the mid frequencies, which accentuates a very low-Q spectral hump between 2 and 6 kHz which is likely to be audible. This is a very common attribute of two-way loudspeakers. — Toole, Floyd E, Sound reproduction- the acoustics and…, 536
