Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Graph with lines labelled "0°" and "180°"; relative dB (0° is 0 dB in the mids). Distance, room and smoothing not stated. Drawn from the left edge (40 Hz) to the right edge (20 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. Three polar plots, 0° up, each with 1 kHz and two other frequencies; rings labelled 0, -6, -12, -18, -24 dB. Measuring conditions not stated.
