vs 75 end-address condensers
More output than 92% of 75 end-address condensers.
Each stripe is one end-address condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 104 end-address condensers
Quieter than 62% of 104 end-address condensers.
Each stripe is one end-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 110 end-address condensers
Takes louder sound than 83% of 110 end-address condensers.
Each stripe is one end-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.

Proximity effect: the bass it gains up close
From the manual, p. 8.
Captioned "Fig. 4. On-axis and diffuse-field responses of DPA 4003, 4006 and 4006-TL with the Free-field Grid DD0251 fitted." Distance and room not stated; relative dB (0 dB line in the mids).
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the manual, p. 9. Approximate
Captioned "Fig. 8 Directional characteristics of DPA 4003, 4006 and 4006-TL with the DD0297 Diffuse-field Grid fitted (normalized)." 5 dB per ring (the "5 dB" marker). Measuring conditions not stated.
Approximate: some frequencies are identified by reasoning, not by the legend: 1k Hz, 5k Hz, 10k Hz, 15k Hz, 20k Hz.
