Studio monitor Neumann KH 420 G

The KH 420, as a result of using the latest technologies in acoustic, electronic and mechanical design, sets new standards in sound reproduction quality. Computer-optimized drivers, a Mathematically Modeled Dispersion™ (MMD™) waveguide, flexible acoustic control, a variety of input options, and a wide choice of mounting hardware allow the KH 420 to be used in a variety of acoustic environments, with equipment from any source and in a variety of locations.

The KH 420 is designed to be used as a middle or main monitor. It is particularly well suited for use in music, broadcast and post-production recording, mixing and mastering studios. The enclosure can be wall-mounted or wall-mounted thanks to the port located on the front panel, and can be freely mixed into a multi-channel system with a wide range of other loudspeakers - Product Selection Guide.
