It combines precise frequency response with powerful amplification, delivering an uncolored and accurate representation of every detail. Equipped with a 10" woofer, 3" midrange driver and 1" tweeter, it covers a wide frequency range from 26 Hz to 22 kHz (±3 dB).
Key Features
- Active 3-way design with Class AB tri-amplification
- Wide frequency range: 26 Hz – 22 kHz
- MMD™ waveguide for consistent dispersion
- Analog acoustic controls and parametric EQ
- LRIM™ cabinet for resonance reduction
- Maximum SPL above 120 dB
Professional Sound Accuracy
Developed as a tool for critical listening, the KH 420 ensures that every nuance of the audio material is reproduced faithfully. Its three-way system with dedicated amplifiers for each driver provides outstanding dynamics and minimal distortion. The MMD™ waveguide delivers wide horizontal dispersion for a stable stereo image and controlled vertical dispersion to reduce unwanted reflections, resulting in neutral sound across different room acoustics.
Applications
The KH 420 is ideal for medium to large control rooms that require powerful yet transparent monitoring. It can be used as a midfield monitor at listening distances of 1.5 to 3 meters or as a main monitor in professional studios. Perfect for mixing, mastering and immersive audio production, it offers absolute control and reliability.
