The KH 420 is an active studio monitor. The KH 420 represents the result of using the latest techniques in acoustical, electronic and mechanical design to bring a new benchmark in audio reproduction quality.In-house computer optimized drivers, a waveguide featuring Mathematically Modeled Dispersion™ (MMD™), flexible acoustical controls, various input options, and an extensive mounting hardware range allow the KH 420 to be used in diverse acoustical conditions, with any source equipment, and in a wide variety of physical locations.
The KH 420 has been designed for use as a mid-field or main monitor. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing, and mastering. The KH 420 can be used free-standing or flush mounted into a wall, and, in multichannel systems, can be mixed freely with other loudspeakers in the range.

- APPLICATIONS
- No standing wave resonances inside cabinet to reduced inter-modulation distortion in mid-range for a more transparent sound to reduced cabinet resonances
- Latest modeling techniques used to minimize non-linear (inter-modulation) distortion for safe use near magnetic storage media
- Low-distortion high-frequency reproduction, robust against accidental physical damage
- Dedicated driver reproduces important mid-range frequencies, which is especially important for speech and vocals. Light weight dome has better transient response and less breakup modes than cone designs
High power magnet reduces harmonic and inter-modulat
- Linear pistonic motor gives a very low harmonic distortion even at high excursions, so reduced air noise and improved rocking modes
- Reduced compression at high output levels. No coloration from organ pipe resonance
- Smoother off-axis response and more forgiving of diverse acoustical environments. The freedom of movement across the mixing console will be reduces reflections off the mixing console
- Displays operation status and activation of the extensive protection system. The dimmable for low lighting level conditions or behind the screen applications
- Improved heat dissipation leading to increased electronics reliability
- Improved transient response, reliability Assurance of safety
- Allows extraction of the maximum performance from the system without reducing reliability
- Any KH 420 is “pair-matched” to any other KH 420
- More control in diverse acoustical environments. Repeatable acoustical settings after moving loudspeakers
- Easier interfacing with signal sources
- Reduced noise in electrically noisy environments and over-comes ground loops
- For flexible and trouble-free digital inter connectivity (24 bit, 192 kHz, AES3 and S/P-DIF)
- To align audio and video signals
- To compensate for listening distance differences
One version works in any country and robust to poor quality mains supply
- Dual supply improves transient response
- More flexibility in mounting cabinets in more diverse locations and backwards compatibility with previous models. Mechanically compatible with O 410, KH 870 and O 870, easy advanced planning for installations can be used, if required, to protect the driver
- Robust wooden flight case for transport and storage
