Audix
D4
Dynamic · Hypercardioid · 40–18,000 Hz · a rider regular
- Same 128 g machined body as the D2, but with the VLM Type D capsule reaching down to 40 Hz — Audix lists floor toms, bass cabs and small kick drums for it.
- Audix gives maximum SPL as ≥144 dB, with no distortion threshold or test condition attached.
Frequency response
No response curve yet.
MicSense only draws a curve redrawn from a graph the manufacturer publishes — it never estimates one from the microphone’s class. No published graph has been redrawn for the D4 yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for hypercardioid. It illustrates the pattern type — it is not a measurement of this individual model.

Specifications: Audix datasheet · last checked 2 Oct 2026. These are the maker’s published figures for this model. A dash never means zero: “not published by the maker” means the maker’s documents give no figure; “not yet checked” means MicSense has not confirmed one yet. Spotted an error? Tell us.
MicSense notes

| Introduced | — not recorded |
Price tier and “a rider regular” are MicSense’s own judgement, not the maker’s.
What it gets used for
- Toms
- Kick in
- Bass cab
- Horn / brass
- Acoustic instrument
MicSense tags microphones by the job on a live stage, not by studio category — so you can filter for “kick in” or “monitor vocal” instead of working backwards from “large-diaphragm condenser”.
D4 alternatives: closest in published specs
Based on published specifications only — always listen at soundcheck. These are the microphones in the MicSense library whose datasheet figures sit closest to the Audix D4’s for the same live job, with the reasons. It says nothing about how they sound.
Not compared for the Audix D4: response curve not redrawn yet.
-
Audix
D2
- Same job: toms, horn / brass
- Same type: dynamic
- Same hypercardioid pattern
- Same form: end-address
- About the same output — within the datasheets’ tolerance
- Max SPL as high or higher (144 vs 144 dB SPL)
-
beyerdynamic
M 88
- Same job: toms, kick in, bass cab
- Same type: dynamic
- Same hypercardioid pattern
- Handheld instead of end-address — mounts differently
- ≈ 6 dB more output — about 6 dB less gain
Not comparable: max SPL not published by the maker

Audio-Technica
ATM650
- Same job: toms
- Same type: dynamic
- Same hypercardioid pattern
- Same form: end-address
- About the same output — within the datasheets’ tolerance
Not comparable: max SPL not published by the maker
