Overview

The Neumann KH 120 MKII is a reference-class active nearfield monitor designed for critical listening environments where mix translation and sonic accuracy are non-negotiable. Its sonic signature is neutral to the point of clinical — the MMD waveguide controls horizontal and vertical dispersion with such precision that early room reflections are reduced before the DSP even engages, delivering a focused, detailed image from the first note. The bi-amplified architecture — 80W independent to both the 5.25" polypropylene woofer and 1" tweeter — means neither driver is ever fighting for headroom. In dense mix contexts with layered low-mids and compressed buses, the KH 120 MKII stays composed where lesser monitors smear and compress, letting you hear your gain staging decisions accurately rather than inferring them.

This bundle pairs the stereo KH 120 MKII set with the MA 1 alignment microphone and Neumann's room correction software, transforming the out-of-box experience from "very good monitor in an imperfect room" to a fully calibrated reference system. The Auray isolation pads decouple the cabinets from desk or stand surfaces, eliminating low-frequency energy transfer that muddies the monitoring field. Build quality is characteristically German — the enclosures are inert, the connectors are robust, and the amplifier section runs cool under continuous studio use. For broadcast, film post, mastering, or any session where every engineer in the room needs to agree on what they're hearing, the KH 120 MKII pair is a professional answer to the question of what you should trust.

Pros & Cons

👍 Pros

  • The MMD waveguide produces an exceptionally wide, stable sweet spot — stereo imaging holds together even when you shift position, which matters across long sessions.
  • Bi-amped 80W-per-driver configuration gives the tweeter and woofer independent headroom, so transient peaks in percussive material stay clean and uncompressed.
  • DSP-controlled crossover alignment is time- and phase-accurate at the listening position, making mid-range clarity and vocal placement in a mix unusually precise.
  • The MA 1 alignment mic bundle adds automatic room correction that meaningfully reduces low-frequency standing wave influence — measurably flatter response without expensive acoustic treatment.
  • Balanced XLR and AES67 connectivity mean these drop cleanly into professional signal chains from any interface or digital console.

👎 Cons

  • The 5.25" woofer reaches its limits below 55 Hz — sub-bass mixing decisions require a matched subwoofer, adding cost and setup complexity to the system.
  • At this price point you're buying a pair plus calibration infrastructure; the total investment including isolation pads and room treatment to honor the monitor's resolution is substantial.
  • The DSP calibration workflow via MA 1 mic and Neumann's software has a learning curve — first-time setup requires time and attention to get the compensation filters right.
  • Physical size and weight make these less ideal for traveling producers or mobile rigs where compact monitors are preferable.

Frequently Asked Questions

No phantom power needed — each monitor is self-powered with bi-amplified Class D amplifiers delivering 80W to both the LF and HF drivers. You connect via XLR balanced analog or AES67 network audio; the power comes from the IEC mains connection on the back of each cabinet.
The onboard DSP handles crossover filtering, driver alignment, and room compensation EQ with precision that analog circuitry can't match. You can trim low-end boundary reinforcement when the monitor is shelf- or wall-adjacent, and the included MA 1 alignment mic plus Neumann's software walks you through automatic room correction — meaning what you hear is the signal, not your room's resonances.
The 5.25" woofer reaches down to approximately 52 Hz (±3 dB), which covers most mix-critical bass detail. For sub-60 Hz judgment you'll want a matching KH 750 subwoofer, but for the majority of tracking, editing, and mid-range mix decisions the low end is tight and accurate with excellent transient definition — kick drum attack is clearly separated from body.
They perform best in a treated space, but the DSP room correction and boundary EQ controls make them far more adaptable than passive monitors. The MMD waveguide controls dispersion tightly, reducing early reflections — so even a moderately treated room with proper placement yields a coherent stereo image and a noise floor that reveals detail most nearfields obscure.
Self-noise is exceptionally low — the KH 120 MKII's amplifier section is engineered to stay inaudible even at close working distances. In a quiet treated room at moderate listening levels, you won't hear the monitors themselves; you'll hear the quietest details in your audio that lower-tier monitors simply bury.
