Neumann KH 420

3-Way Midfield Monitor

The KH 420 from Neumann is a three-way active monitor designed for use as a mid-field or main monitor, and can be used free-standing or flush mounted into a wall. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing and mastering, and in multi-channel systems can be mixed freely with other loudspeakers in the range.

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.
