Neumann's KH 420 provides 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.

Key Features:

No standing wave resonances inside cabinet Reduced intermodulation distortion in midrange for a more transparent sound Reduced cabinet resonances.

Latest modeling techniques used to minimize non-linear (intermodulation) distortion For safe use near magnetic storage media.

Dedicated driver reproduces important midrange 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 intermodulation distortion.
