The Neumann KH 120 II US is a compact nearfield studio monitor designed for critical listening in editing suites, project studios, broadcast rooms, and mobile production setups. It builds on the established KH monitoring approach with improved low-frequency extension, higher output capability, and tighter consistency, giving engineers a reliable reference in smaller control rooms and secondary mix environments.

Its internal DSP supports phase-linear crossover behavior and room-adaptive alignment when used with Neumann MA 1 software. That makes the KH 120 II US especially useful where placement constraints or room acoustics can compromise monitoring accuracy. Analog XLR and S/PDIF connectivity allow integration into a wide range of professional workflows, from traditional interfaces to digital playback chains.

For users working at a recommended listening distance of 1 to 2 meters, this model is suited to stereo production, editing, overdub rooms, surround duties, and portable control room applications. The front-ported bass reflex design helps with practical placement, while the Mathematically Modelled Dispersion waveguide supports consistent imaging and stable monitoring across the listening area.
