Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Titled "Frequency Response"; relative dB. Distance, anechoic or not, smoothing and typical-vs-individual are 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 Pattern, Measured at 1000 Hz" (as printed, though it shows five frequencies); two plots, 250 Hz to 1 kHz and 2500 to 8300 Hz; 0° at the bottom, 5 dB per ring down to -20 dB. Measuring conditions not stated. Approximate some frequencies are identified by reasoning, not by the legend: 8.3k Hz.
