Three-Way Active Studio Monitor

Overview

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 KH 420 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.
