Distance

Frequency response: from the spec sheet (Recording Hacks copy), p. 2. Titled "Frequency Response", graph marked "AVERAGE RESPONSE"; relative dB, 0 dB labelled. 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 (Recording Hacks copy), p. 2. Titled "Polar Response", one full-circle plot, legend "1000 Hz", "(5 dB per division)"; the rings are not labelled. Measuring conditions not stated. Approximate reading error up to about 1 dB; the graph's dB scale is not labelled and was assumed.
