AKG D112
Large dynamic cardioid for kick drum and bass cabinets (the original egg-shaped D112, successor to the D 12)
Approximate Some readings for this mic are uncertain; see the graphs.
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.

5 of 9; all under Recommended for.
Proximity effect: the bass it gains up close
From the manual (Recording Hacks copy), p. 13. Approximate
Titled "Frequenzkurve"; relative dB. Curves labelled "10 cm", "1 m" and "180°" (at 1 m); room not stated.
Approximate: reading error up to about 1 dB.
That unit is from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (CC BY 4.0), measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's curve.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the manual (Recording Hacks copy), p. 13. Approximate
Titled "Polardiagramm"; two half-plots, 125 Hz to 1 kHz on the left and 2 to 16 kHz on the right, 0° at the bottom, rings every 5 dB from 0 to -30 dB. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
