Neumann KH 420 G – 3-Way Midfield Active Studio Monitor (Single, Grey)

Uncompromising Accuracy for Critical Listening

The Neumann KH 420 G is a 3-way active midfield studio monitor built to deliver reference-grade sound in professional studios. Engineered for supreme accuracy, wide dynamic range, and minimal distortion, the KH 420 is ideal for mixing, mastering, and critical post-production work. Its unique sealed cabinet design, precision drivers, and Mathematically Modeled Dispersion™ (MMD™) waveguide ensure consistent and neutral sound reproduction across all frequencies.

Designed to integrate seamlessly into modern studio environments, the KH 420 provides superb imaging and tonal balance, even in acoustically challenging spaces.

Three-Way Monitoring Redefined

The KH 420 features a 10-inch composite sandwich woofer, a 3-inch soft dome midrange driver, and a 1-inch titanium fabric dome tweeter—each powered by its own dedicated Class AB amplifier. This tri-amplified design delivers exceptional clarity and punch, with a frequency response that extends from 26 Hz to 22 kHz.

With phase-linear analog crossovers and advanced cabinet engineering, the KH 420 ensures that transitions between lows, mids, and highs remain coherent and smooth, making it easier to make precise mix decisions.

Made for High-SPL Environments

Built for medium to large control rooms, the KH 420 can deliver up to 122.4 dB SPL with low distortion, making it suitable for immersive audio formats, 5.1/7.1 setups, and LCR midfield monitoring. The rear panel includes extensive acoustic controls for room adaptation, and optional digital input modules (DIM 1) are available for AES and networked environments.
