Neumann KH420 Active 3-Way Studio Monitor

KH 420 Description

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 KH420 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.

Main features of the Neumann KH420 active monitor include:

  • Computer mechanically modeled three-way cabinet design using Low resonance Integral Molding leaving No standing wave resonances inside cabinet and providing reduced intermodulation distortion in the midrange making a more transparent sound.
  • New in-house simulated magnetically shielded drivers using the latest modeling techniques to minimize non-linear (intermodulation) distortion for safer use near magnetic media storage.
  • Alloy fabric dome tweeter with built-in grille providing a high frequency, low-distortion high-frequency reproduction and protection the drivers against accidental damage.
  • Fabric dome midrange driver using a neodymium magnet, reproducing important midrange frequencies, important for vocal and speech sources. The high powered magnet reduces harmoni and intermodulation distortion.
  • Long throw bass driver with Linear Force Factor™ and flow optimized die cast basket gives a very low harmonic distortion even at high usage.
  • High-capacity flow-optimized bass reflex ports with pipe damped which reduces compression at high output levels with no coloration from organ pipe resonance.
  • A smoother off axis and a reduction of reflections is acheived by using hte Elliptical Mathematically Modeled Dispersion waveguide for use in more challenging acoustic enviroments.
  • An improved transient response and headroom is gained with its analogue Class A/B amplifiers and limits overheating.
  • A 4-position bass, low-mid and treble controls and an easy to use parametric equaliser give a freedom of control in any enviroment.
