Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 3. Captioned "Typical on and off-axis response of a 4015A measured at 60 cm (23.6 in)". The product page adds: "On-axis (0°) measured at 60 cm (23.6 in), other directions measured in the far field." Drawn solid from 40 Hz to 20 kHz, dotted outside.

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. 4. Captioned "Typical directional characteristics of a 4015A"; 5 dB per ring, centre -25 dB. Measuring conditions not stated. Approximate reading error up to about 1 dB; some frequencies are identified by reasoning, not by the legend: 250 Hz, 1k Hz.
