Neumann KH 350 Three Way DSP-Powered Midfield Monitor (Each)

About: Neumann KH 350 Three Way DSP-Powered Midfield Monitor (Each)

The KH 350 is a high performance three way monitor combining deep low frequency extension and tightly controlled dispersion with advanced DSP integration. Optimized for medium-sized rooms and immersive environments, it delivers full range accuracy, refined midrange detail, and seamless room alignment via MA 1 (optional).

• Designed for both nearfield and midfield applications
• Powerful low frequency extension down to 30 Hz (±3 dB)
• Uniform dispersion pattern across the entire spectrum
• DSP engine for improved performance and MA 1 room correction

The KH 350 expands Neumann’s portfolio into true midfield monitoring, delivering the power, low frequency authority and control required for listening distances ranging from 1.2 to 3 m (4 to 10 ft) and immersive production environments. As it shares Neumann’s consistent tonal DNA, the KH 350 may be combined with other KH-Line monitors in immersive setups.

The KH 350 impresses with deep and powerful low-end response, enormous headroom, and exceptional linearity across the entire musical spectrum (32 Hz – 20 kHz ±1.25 dB).

Neumann’s Mathematically Modeled Dispersion (MMD) waveguide shapes the sound radiation to deliver precise and consistent dispersion throughout the room. This ensures stable imaging and greatly reduces unwanted reflections, supporting accurate monitoring even at longer listening distances while remaining fully capable in nearfield setups.

Built on Neumann’s advanced DSP engine, the KH 350 supports MA 1 Automatic Monitor Alignment, offering highly accurate frequency and phase optimization. Analog and digital AES3id inputs (BNC) integrate seamlessly with Neumann’s KH subwoofers and monitor control solutions, enabling flexible system scalability from stereo to immersive environments. 

Industry leading tight manufacturing tolerances ensure consistent unit to unit matching and predictable performance across multi monitor installations: perfect translation to all playback systems for music production, mixing, and mastering in stereo or immersive formats, as well as film scores, broadcast, and post production workflows. 

Controlled Directivity for Accurate Monitoring From Nearfield to Midfield 

The advanced waveguide geometry guarantees stable imaging at recommended distances of 1.2 – 3.0 m (4 – 10 ft), while remaining fully capable in closer nearfield setups where higher LF authority and directivity control are crucial.

Deep and Powerful Low Frequency Extension for Full Range Authority 

The bass reflex design provides powerful headroom and extension down to 30 Hz (±3 dB), delivering a reliable full range reference with excellent translation.

High Resolution Midrange Performance for Detailed, Confident Decision Making

The KH 350 combines Neumann’s proven mid/tweeter platform with its MMD waveguide, delivering controlled midrange directivity and precise vocal definition optimized for its size class, longer listening distances, and immersive setups.

MA 1 Ready for Perfectly Aligned Stereo and Multichannel Setups

The integrated DSP platform enables precise MA 1 alignment, improving frequency and phase response in any room and ensuring consistent accuracy from stereo nearfields to complex immersive installations.

• Reliable full range reference with excellent translation
• Precise directivity for nearfield and midfield distances
• Deep LF extension (30 Hz ±3 dB) with impressive headroom
• DSP engine for improved performance and MA 1 room correction
• Ideal for immersive LCR and larger multichannel systems
• Seamless integration with network enabled KH subwoofers
