Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. "12" or more on axis" (about 30 cm), as printed. Anechoic or not, smoothing and typical-vs-individual are not stated. No dB labels on the graph: scaled from its 10 dB bar and set to 0 dB at 1 kHz.

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. Full circle, 0° up; values fold left and right halves. Measuring conditions not stated.
