Advanced Compact Monitor from Neumann
The Neumann KH 150 is a bi-amplified studio monitor with reference-grade performance that belies its compact size, making it ideal for both nearfield and midfield use in small-to-mid-sized control rooms. Its newly developed 6.5-inch woofer, born from more than three years of intensive research and development, is housed in a precisely engineered 20-liter bass reflex cabinet. This design delivers deep, tight bass extension down to 39Hz and a powerful maximum SPL of 118dB, while a specially designed 1-inch tweeter provides pristine clarity up to 21kHz. Driven by energy-efficient Class D bi-amplification — 145 watts for the woofer and 100 watts for the tweeter — and enhanced by Neumann’s Mathematically Modeled Dispersion (MMD) waveguide, the KH 150 offers exceptional accuracy across a wide sweet spot while minimizing desk reflections.
A Crowning Technical Achievement
DSP-driven electronics unlock advanced modern features such as phase-linear performance for rock-solid imaging and room-adaptive calibration via Neumann’s cutting-edge MA 1 Automatic Monitor Alignment system. Whether used as a stereo pair or integrated into immersive surround setups with other KH series monitors, the KH 150 delivers exactly what is in your mix. Staying true to Neumann’s monitoring philosophy — ruler-flat linearity, vanishingly low distortion, zero coloration, and seamless room integration — the KH 150 gives you the confidence to hear every detail and make mix decisions that translate reliably beyond your studio.
Mixes That Translate
Midrange clarity is the heart of every mix, and the KH 150 excels where it matters most. Inferior monitors can lead to long hours of guesswork, listening fatigue, and mixes that fail to translate. The KH 150 removes that uncertainty, allowing you to work faster, more confidently, and more creatively. Its exceptionally linear phase response delivers astonishing transparency in the midrange and remarkable accuracy in the time domain, revealing subtle details such as low-level reverb tails. Thanks to DSP-controlled crossovers that avoid the phase distortion of analog filters and extremely tight tolerances of less than ±0.8dB, the KH 150 produces razor-sharp stereo imaging and precise placement of vocals, bass, and instruments.
Room-ready Performance
Even the best monitors are only as accurate as the room they are in. Neumann’s MMD waveguide creates a wide, consistent listening area while reducing desk reflections, but the KH 150 goes further. Its internal DSP integrates seamlessly with the optional MA 1 Automatic Monitor Alignment system to adapt the monitor precisely to your room acoustics and listening position. Even in acoustically treated spaces, this calibration delivers a noticeable and meaningful improvement in accuracy and consistency.
From Rock to Bach — and Beyond
With powerful amplification, advanced protection limiters, extended low-frequency performance, and high SPL capability, the KH 150 is perfectly suited for EDM, rock, metal, urban music, and film scoring, as well as any application requiring deep bass and elevated listening levels. Crucially, clarity and coherence are maintained even at high volumes. At the same time, the KH 150 shines when reproducing the fine nuances of classical music, acoustic jazz, broadcast content, ADR, and voice-over work. Versatile, revealing, and uncompromising, the Neumann KH 150 continues the company’s legacy of world-class transducer innovation that began in 1928.
What Neumann says...
DSP-Powered Precision with Deep Bass Performance
- DSP-powered, bi-amplified studio monitor with deep bass response and outstanding resolution
- Linear frequency and phase response
- DSP engine for improved performance and automatic room alignment
- Deep low end down to 39 Hz with high SPL capability
- Analog and S/PDIF connectivity
The KH 150 is a powerful bi-amplified studio monitor delivering true reference-class performance. Its 6.5-inch woofer, housed in a carefully engineered bass reflex cabinet, produces stunning low-end extension and high SPL capability without sacrificing clarity. DSP-controlled electronics ensure linear phase response and enable room-adaptive calibration via Neumann’s revolutionary MA 1 Automatic Monitor Alignment system.
What You Hear Is What You Get
The KH 150 follows the core philosophy shared by all Neumann studio monitors: highest linearity, lowest distortion, zero coloration, and perfect adaptability to any acoustic environment. It reveals every nuance in your tracks, removing guesswork from the mixing process and allowing faster, more confident, and more creative decisions.
One Bigger
What sets the KH 150 apart from its smaller siblings is its deeper bass extension down to 39 Hz, approaching the performance of the larger KH 310. This is achieved through a newly developed 6.5-inch high-precision woofer and optimized bass reflex design. With powerful amplifiers (145 W LF / 100 W HF) and advanced protection limiters, the KH 150 maintains exceptional clarity even at elevated listening levels, making it ideal for EDM, urban music, film scoring, and other bass-intensive applications—while remaining equally capable for rock, classical, broadcast, and voice-over work.
Exceptional Linearity and Imaging
The KH 150 delivers an exceptionally linear frequency response from 39 Hz to 21 kHz (±3 dB) and also linearizes the phase response. This results in transparent mids, precise impulse reproduction, and finely resolved reverbs. DSP-controlled crossovers avoid the phase distortion inherent in analog filters, while extremely tight production tolerances of no more than ±0.8 dB ensure razor-sharp stereo imaging.
Ready for Your Room
Even the best loudspeaker is only as accurate as the room allows. Neumann’s Mathematically Modelled Dispersion™ (MMD™) waveguide provides a wide sweet spot and minimizes desk reflections. Going further, the KH 150’s internal DSP enables room calibration via Neumann’s MA 1 Automatic Monitor Alignment system (sold separately), ensuring optimal adaptation to your room and precise calibration for your listening position.
Flexible Integration
Tonal compatibility with other KH line studio monitors allows the KH 150 to be seamlessly integrated into mixed, surround, or immersive monitoring setups. For flexible system design, the monitor features both analog and digital inputs.
AES67 – Audio over IP
The KH 150 AES67 variant includes integrated redundant AES67 Audio over IP network ports, fully compliant with broadcast standards such as ST 2110, ST 2022-7 redundancy, and RAVENNA. It is also compatible with DANTE®-generated AES67 network streams, making it ideal for modern networked studio and broadcast environments.
Energy Efficient
Neumann’s patent-pending Class D amplifier technology combines superior audio performance with exceptional energy efficiency. Despite delivering up to 145 W to the woofer and 100 W to the tweeter, the KH 150 consumes only 17 W at idle. An auto-standby function further reduces power consumption to just 0.3 W when not in use and can be disabled if desired.
Mounting Options and Finish
Most KH 120 mounting accessories are compatible with the KH 150, with updates made to accommodate its larger size and weight. The KH 150 is available in anthracite or white finishes, allowing it to blend seamlessly into a wide range of studio environments.
