Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 1. "Polar pattern and frequency response"; axis labelled "dBV" but 0 near 1 kHz, so relative. 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. 1. Each frequency is drawn on one side only (125 to 1000 Hz left, 2000 to 16000 Hz right); the pattern is taken as symmetric. Rings every 5 dB, 0 to 25. Measuring conditions not stated.
