Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Titled "Frequency response"; relative dB (axis labelled "dBm", +10 to -10). Distance, room and smoothing not stated.

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

Polar pattern

Polar pattern: from the spec sheet, p. 2. Titled "Polar patterns"; two plots, "Lo" (125 Hz to 1 kHz) and "Hi" (2 to 16 kHz), full circles, 0° at the right. Scale "dBSPL" from 0 at the outer circle to -36 at the centre. Measuring conditions not stated. Approximate reading error up to about 1 dB.
