The Neumann KH 120-A Studio Monitor combines a 1″ titanium fabric dome tweeter powered by 50 W RMS (80 W peak) of analog amplification with a 5.25″ long throw composite sandwich cone bass driver powered by 50 W RMS 80 W peak) analog amplification with dual front panel bass ports. The two speaker drivers are mounted in an elliptical mathematically modeled dispersion waveguide for smoother off-axis response and a more forgiving sound signature in different acoustical environments.

The front panel OF THE Neumann KH 120-A is made from one piece without discontinuities to reduce diffraction with protective metal grills and the cabinet is made of magnetically shielded aluminum to reduce resonances, improve heat dissipation, and extend the operating lifetime of the unit. The monitor is suitable for professional tracking, mixing, and mastering applications in broadcast, project, and post-production studios.

The system delivers a free field frequency response of 52 to 21,000 Hz with 4-position bass, low-mid, and treble acoustical controls for tailoring the response to different rooms and an input gain control from 0 to -15 dB. The front panel Neumann logo functions as an LED indicator for power and clip/limiting but can also be dimmed for light applications and for use when placed behind screens. A variety of wall, ceiling, truss, subwoofer, stand, and surface mounting options are available through a range of accessories (sold separately).
