NARROWER at the bottom and wider at the top than the microphone pair's 60–4000 Hz, and for
reasons that belong to a room rather than to a drum kit: below ~125 Hz a hall's modal field
decorrelates the direct sound from the feed, and the wavelength is long enough that arrival
time is not what the phase there is describing. The ceiling stays where the mic pair's is —
air absorption and box directivity take the coherence away above it.
DECLARED, not tuned: the first rig reading (spec §9, "how the fit behaves at room-scale
delays... is a measurement, not an argument") is what may move it, on evidence.
The band the room fit is taken over.
