Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 1. "Frequency Response", "12" or more on axis" (about 30 cm). No dB labels: scaled from the "10 dB" bar and set to 0 dB at 1 kHz. 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. "Polar Pattern", full circle, 0° up; "SCALE IS 5 DECIBELS PER DIVISION". Measuring conditions not stated.
