Neumann’s Advanced AES67-Equipped Compact Monitor
The Neumann KH 150 AES67 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. A newly developed 6.5-inch woofer, the result of more than three years of intensive R&D, is housed in a precisely engineered 20-liter bass reflex cabinet, delivering deep, tight bass extension down to 39Hz and a maximum SPL of 118dB. A specially designed 1-inch tweeter provides crystalline high-frequency clarity up to 21kHz. Driven by efficient Class D bi-amplification (145W LF / 100W HF) and enhanced by Neumann’s Mathematically Modeled Dispersion (MMD) waveguide, the KH 150 AES67 delivers exceptional accuracy across a wide sweet spot while minimizing desk reflections.
Network-Ready
In addition to analog and S/PDIF inputs, the KH 150 AES67 features integrated redundant AES67 Audio over IP network ports. These ports are fully compliant with professional broadcast standards including ST 2110, ST 2022-7, Ravenna, and Dante-generated AES67 streams. This makes the KH 150 AES67 an ideal monitoring solution for modern networked studio facilities that demand uncompromising performance in a compact footprint.
A Crowning Technical Achievement
DSP-driven electronics unlock advanced signal processing capabilities, including phase linearity for rock-solid imaging and room-adaptive calibration via Neumann’s MA 1 Automatic Monitor Alignment system. Whether deployed as a stereo pair or combined with other KH series monitors for immersive surround applications, the KH 150 AES67 delivers ruler-flat linearity, vanishingly low distortion, zero coloration, and seamless integration into any acoustic environment. The result is absolute confidence in critical recording and mixing decisions.
Mixes That Translate
Exceptional midrange clarity lies at the heart of the KH 150 AES67’s performance, ensuring accurate balance and reduced listening fatigue. Its remarkably linear phase response yields transparent mids and precise time-domain accuracy, revealing fine details such as low-level reverb tails. DSP-controlled crossovers eliminate phase distortion typical of analog designs, while extremely tight tolerances of less than ±0.8dB ensure tonal consistency. The result is razor-sharp stereo imaging that makes it easier to place vocals, bass, and instruments with confidence across all playback systems.
Room-Ready
The interaction between monitors and room acoustics is critical, especially at higher listening levels. Neumann’s MMD waveguide creates a broad sweet spot while reducing reflective interference from consoles or desks. Beyond physical acoustics, the KH 150 AES67’s internal DSP integrates seamlessly with the optional MA 1 Automatic Monitor Alignment system, allowing precise calibration to your room and listening position for optimal accuracy.
From Rock to Bach — and Beyond
With powerful amplification, advanced protection limiting, robust low-frequency performance, and high SPL capability, the KH 150 AES67 excels in demanding genres such as EDM, rock, metal, and urban music, as well as film scoring and broadcast applications. At the same time, it reveals the nuance and detail required for classical, jazz, ADR, and voice-over work. This versatility underscores Neumann’s long-standing legacy of transducer innovation, making the KH 150 AES67 a truly world-class monitoring solution.
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.
