Neumann KH 420 (Pair)

The Neumann KH 420 is a 3-way active studio monitor and an update on the highly praised Klein and Hummel O410 featuring the latest technique in acoustical, electronic and mechanical design.

The Neumann KH 420 is designed for use as a main monitor in medium sized studios or mid field monitors in large facilities. Designed to be used in music production, broadcast and post-production, the KH 420 monitors are equally at ease during, tracking, mixing or mastering as well as part of a multi-channel setup.

Designed to represent a new benchmark in audio reproduction, the KH 420 monitors feature a new Mathematically Modelled Dispersion (MMD) waveguide, optimised drivers and acoustical controls to provide the best possible sound in most situations. The 10” long-throw bass driver uses Extremely Linear Force Factor (ELFF) technology and a die-cast basket optimised to allow the most power and direct sound reducing unwanted smearing of the bass, while the specifically designed bass reflex port with damped pipes provides additional power and extended Low frequency response. A 3” Mid driver and 1” Tweeter make full use of Neumann’s MMD wave guides with wide horizontal and narrow vertical planes offering a wide and focused sweet spot. The mid driver and tweeter can be rotated to use the studio monitors horizontally or vertically while providing the optimum sound diffraction.

The back of the monitors provide an impressive amount of controls from acoustical controls offering Low, Mid and HF cuts, complemented by a three-band parametric EQ with crossover controls ensures that the monitors fit perfectly in your room. An additional Gain control offers an Output Level control which activates the different stages of the powerful Class AB amplifier. This is complemented by an input gain knob to ensure optimum gain structure.
