Frequency response

Angle
Distance

Frequency response: from the near far image. Captioned (on the product page) "Frequency response of the 4088 in near and far field"; the distances are not stated (the main graph gives 2-3 cm for near field). The far-field line is drawn dashed from 100 Hz to where it meets the near-field line (about 900 Hz) and dotted below 100 Hz; above that the two are one line.

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

Polar pattern

Polar pattern: from the polar image. Captioned (on the product page) "Typical directional characteristics of a 4088"; 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: 500 Hz.
