Frequency response

Angle
Distance

Frequency response: from the spec sheet 2011 rh, p. 2. Titled "FREQUENCY / POLARS"; "dBm", 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 2011 rh, p. 2. Two full-circle plots ("Lo": 125 Hz to 1 kHz; "Hi": 2 to 16 kHz), "dBSPL" from 0 to -36 dB, each frequency drawn at its own level. Measuring conditions not stated. Approximate reading error up to about 1 dB.
