Frequency response

Angle
Distance

Frequency response: from the manual, p. 14. Capsule on a CMC 6 amplifier ("+ CMC 6"), as printed. Free field, distance and smoothing not stated; the sheet draws a tolerance band (dashed) around the curve.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the catalog, p. 5. Rings every 5 dB, labelled 0 to -30 dB (the centre); 0° at the top. Left half 250 Hz to 2 kHz, right half 4 to 32 kHz; the pattern is taken as symmetric. Amplifier and measuring conditions not stated.
