vs 204 condensers
More output than 20% of 204 condensers.
Each stripe is one condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 258 condensers
Quieter than 8% of 258 condensers.
Each stripe is one condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 277 condensers
Takes louder sound than 45% of 277 condensers.
Each stripe is one condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.

Captioned (on the product page) "Typical on and off-axis response of a 4066", with the note "Dotted line is with high boost grid and solid line with soft boost grid." Only an on-axis line per grid is drawn; distance not stated.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the spec sheet, p. 3. Approximate
Captioned "Typical directional characteristics of a 4066" (2024 print, p. 3); 5 dB per ring, centre -25 dB. Grid and measuring conditions not stated.
Approximate: reading error up to about 1 dB; some frequencies are identified by reasoning, not by the legend: 2k Hz.
