Frequency response: from the spec sheet (Recording Hacks copy), p. 1. Legend: solid "Switch on brilliance setting", dotted "Dip resulting from bass control". Distance and room not stated. Approximate reading error up to about 1 dB.

Independent measurement: also drawn, from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (Juan Carlos Franco Hernández, Bogdan Bacila, Tim Brookes, Enzo De Sena, University of Surrey) (CC BY 4.0): one unit, measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's curve.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
