Shure

KSM313/NE

Ribbon · Figure-8 · 30–15,000 Hz

  • A Roswellite ribbon rather than aluminium — it recovers its shape after the blast of air that would stretch a conventional ribbon permanently.
  • 146 dB SPL from a ribbon, which is why this one gets put in front of a guitar cab instead of near it.
  • Dual-voice: the two sides of the ribbon are voiced differently, so turning it around changes the sound.

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 KSM313/NE yet, so the numbers are in the spec table below.

Polar pattern

Generated from the first-order directivity formula for figure-8. It illustrates the pattern type — it is not a measurement of this individual model.

Price tier and “a rider regular” are MicSense’s own judgement, not the maker’s.

What it gets used for

  • Guitar cab
  • Horn / brass
  • Overhead

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”.

KSM313/NE 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 Shure KSM313/NE’s for the same live job, with the reasons. It says nothing about how they sound.
