Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Untitled graph under "Frequency Response and Polar Pattern". Distance, room, smoothing and typical-vs-individual are not stated. The rated response is 30 - 15,000 Hz ± 3 dB.

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 and the front and rear lobes are drawn alike. Measuring conditions not stated. The back of the ribbon is in reversed phase (cut sheet p. 1). Approximate reading error up to about 3 dB; the graph's dB scale is not labelled and was assumed.
