Neumann KH 420

The Neumann KH 420 A is a high-end 3-way active studio monitor designed for reference-grade accuracy in professional mixing, mastering, and broadcast environments. Featuring a 10-inch woofer, 3-inch midrange driver, 1-inch tweeter, and Mathematically Modelled Dispersion™ (MMD™) waveguide, it delivers extremely precise imaging, extended frequency response down to 26 Hz, and powerful, transparent sound reproduction.

The Neumann KH 420 A is a flagship 3-way active studio monitor engineered for the highest level of accuracy and transparency in professional audio production. Designed for demanding recording, mixing, mastering, and broadcast applications, it combines advanced acoustic engineering, powerful amplification, and precise dispersion control to deliver an uncompromised reference listening experience.

At its core, the KH 420 A features a 10-inch woofer, 3-inch dedicated midrange driver, and 1-inch high-frequency tweeter arranged in a carefully optimized 3-way configuration. This design allows each frequency band to be reproduced with exceptional clarity, reducing distortion and intermodulation while ensuring maximum detail and dynamic range across the entire spectrum.

The system incorporates Mathematically Modelled Dispersion™ (MMD™) waveguide technology, which ensures controlled sound radiation and highly stable imaging across a wide listening area. This results in accurate stereo perception even outside the primary sweet spot, making it ideal for large control rooms and professional studio environments.

With a frequency response extending from 26 Hz to 22 kHz (±3 dB), the KH 420 A delivers deep, authoritative bass alongside smooth, highly detailed highs and a natural midrange. Its powerful built-in amplification system (295 W for low frequencies, 130 W for midrange, and 130 W for high frequencies) provides high headroom and consistent performance even at elevated monitoring levels.

Flexible acoustic controls allow precise tuning of the monitor to suit different room acoustics and installation conditions. Combined with robust cabinet construction and extensive mounting options, the KH 420 A can be integrated into a wide range of professional setups, from stereo control rooms to immersive multi-channel systems.
