Neumann KM 184

A ruthlessly clear, unyielding small-diaphragm condenser — brilliant on everything except what it won’t let you shape.

The KM 184 is a fixed-cardioid small-diaphragm condenser microphone built for clarity, durability, and extreme SPL handling — not for shaping or adapting.

Chapters & takeaways4
  1. 1:04
    What it is

    It’s a fixed-cardioid small-diaphragm condenser — no patterns, no pads, no compromises.

  2. 2:39
    How loud it goes

    It handles 138 dB SPL — loud enough for jet-powered ski boats at six inches.

  3. 4:12
    What it feels like to use

    It’s durable, clean, and responsive — and makes an unbeatable matched pair.

  4. 6:06
    What it withholds

    It trades flexibility for fidelity — no controls, just clarity and headroom.

Worth your time?

Yes. Use the whole thing.

The written brief1 min read

What it is and what it was built for

The KM 184 is a fixed-cardioid small-diaphragm condenser microphone built for studio and location recording of acoustic instruments and high-SPL sources.

How it works, in terms a player would use

It is a small-diaphragm condenser microphone. It captures sound with high clarity and directionality. It handles loud sources without distortion up to 138 dB SPL.

What it does better than anything else

It delivers unmatched clarity and directional precision in a compact, rugged package. Its 138 dB SPL rating lets it capture aggressive transients — like percussion, brass, or guitar cabinets — without clipping.

What it does badly

It does not offer pattern switching, pad switches, or low-cut filters. It gives no control over its frequency response or sensitivity beyond placement and preamp gain.

What people made with it

Users have recorded acoustic guitars, strings, piano, woodwinds, and percussion with it. One user placed it six inches from a jet-powered ski boat.

Who should use it, and who should not

Studio engineers and location recordists who value transparency, durability, and headroom should use it. Those needing versatility in pattern, filtering, or attenuation should look elsewhere.

Is it worth your time

Yes — if you need a durable, clean, responsive small-diaphragm condenser for acoustic sources or high-SPL applications. No — if you need extended low-end response, variable polar patterns, or built-in attenuation.

Neumann KM 84NeumannThe Neumann KM 84 is a studio-only small diaphragm condenser microphone. It delivers clean, crisp, accurate recordings of acoustic instruments—no low-end filtering needed. Its presence peak adds clarity; its rapid top-end roll-off removes air. Proximity effect forces tight mic placement. Phantom power is required. It is fragile and unsuited for live or field work.

Neumann U 89NeumannThe Neumann U 89 is a 1980 large-diaphragm condenser microphone built for versatility: five polar patterns via rotary switch, two fixed low-cut filters (80 Hz and 160 Hz), an attenuator, 140 dB SPL handling, and a neutral, less vivid tonal character than the U 87. It excels at distance capture and fits where bulkier mics cannot. It does not offer colouration, warmth or extended sub-bass response. No recordings or users are named in the source material.

Neumann TLM 170NeumannThe Neumann TLM 170 is a discontinued large-diaphragm condenser microphone built solely for studio recording. It offers five polar patterns, a -10 dB pad, and a low-cut switch. It ships with a swivel mount and supports U87-style suspension. It fails in live performance. No recordings, artists or sessions are documented in the source material.

Neumann U 87Neumann · 1967The Neumann U 87 is a large-diaphragm condenser microphone introduced in 1967 as the solid-state successor to the U 67. It features a 25.4 mm diaphragm and three selectable polar patterns — cardioid, omnidirectional, and figure-8. It can be powered by 48V phantom power or two internal 22.5V batteries. The original used the K 87 capsule, a modified version of the K 67. The 1986 U 87A reverted to the standard K 67 capsule and eliminated the dual-battery requirement.
