Sennheiser
e 901
Boundary · Cardioid · 20–20,000 Hz · a rider regular
- A half-cardioid boundary condenser that lies on a cushion inside the kick drum — no stand, nothing to kick over.
- 0.5 mV/Pa from a condenser is remarkably quiet, and deliberately so: it lives at 130 dB SPL and above.
Frequency response
No response curve yet.
MicSense only draws a curve traced from a graph the manufacturer actually publishes — it never estimates one from the microphone’s class. Sennheiser publishes figures for the e 901 but no response graph, so the numbers are in the spec table below and the chart stays empty.
Polar pattern
Generated from the first-order directivity formula for cardioid. It illustrates the pattern type — it is not a measurement of this individual model.

What it gets used for
- Kick in
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”.

MicSense lets you put up to four microphones side by side — spec table, overlaid response curves and polar diagrams on one screen. Free with a free Squaresmile account.
