Exceptional Midfield Monitor from Neumann

When sonic accuracy and absolute clarity are critical, consider adding Neumann's KH 420 powered monitor to the studio space. This midfield monitor excels in several applications — from music production to mixing and mastering, broadcast, and beyond — with the KH 420 delivering a natural, clear sound across a range of 5–9 feet. Like all of Neumann's offerings, the KH 420 offers professional, optimized performance partly owed to its Mathematically Modeled Dispersion waveguide and narrower vertical dispersion, cutting down on unwanted reflections in the workspace. Music Experience's studio vets thoroughly appreciate the KH 420's tri-channel amplifiers, delivering sound pressures up to 122.4dB for an organic tone across the entire frequency spectrum and unmatched bass response down to 26Hz. And since the KH 420's cabinet leverages Low Resonance Integral Molding materials, unwanted resonances and pesky intermodulation distortion issues are a thing of the past, which is made all the better given Neumann's unique fabric dome reproduces the midrange like never before. Powerful, precise, and premium: Neumann's KH 420 is the midfield studio monitor discerning professionals demand.

What Neumann says...

Powerful Tri-Amplified Midfield Studio Monitor

The Neumann KH 420 delivers high-precision dispersion with tremendous sound level reserves, making it ideal for music production, mixing, mastering, broadcast, and post-production applications. With a working distance of 1.5 to 3 m (5’ to 9’), this midfield monitor provides neutral, clear, and detailed sound in any acoustic environment. Its tri-amplified design, low-resonance cabinet, and Mathematically Modeled Dispersion™ waveguide ensure precision and minimal unwanted reflections.
