The KH 120 II is based on the same concept as its acclaimed predecessor but completely re-engineered for improved performance in all parameters: deeper bass, higher SPL capability and even better resolution. Internal DSP power allows for phase linear crossovers and room adaptive alignment via Neumann’s revolutionary MA 1 Automatic Alignment.
When Neumann released the KH 120 A in 2010, it was the beginning of an ongoing success story. Neumann monitoring has since become the reference of choice in countless studios around the world. The KH 120 II follows the same philosophy as its predecessor and, in fact, all Neumann studio monitors: highest linearity, lowest distortion, no coloration, and perfect adaptability to any acoustic environment. Thanks to improved performance in all parameters and a powerful DSP engine, the KH 120 II enables you to hear your tracks with even greater clarity and work more efficiently. Create mixes that translate optimally to all playback systems. With ease.
The KH 120 II has an exceptionally linear frequency response from 44 Hz to 21 kHz (±3 dB). Not only that: It also linearizes the phase response! Which translates to clear mids with astonishing transparency as well as extreme accuracy in the time domain: precise impulse reproduction and finely resolved reverbs. This is made possible by DSP controlled electronics which allow for sophisticated crossovers avoiding the phase distortion caused by analog filters. The internal DSP also realizes new standards in tonal consistency. The KH 120 II is made to extremely low tolerances of no more than ±0.5 dB! And you can hear it, too: Stereo imaging is razor-sharp.
The KH 120 II is designed for nearfield applications with a recommended listening distance of 1 – 2 meters (3 – 6 ft.). It is thus ideally suited to smaller rooms such as home and project studios as well as mixing and editing suites or as a surround speaker in large multichannel applications. Thanks to its outstanding linearity in a portable format, the KH 120 II is also an excellent choice for creating a professional quality makeshift control room when working on location (e.g. orchestra/choir, live recording, film, broadcast).
Even the best loudspeaker only sounds as good as the acoustic environment allows. Neumann’s Mathematically Modelled Dispersion™ (MMD™) waveguide guarantees a wide sweet spot and minimizes desk reflections. But the KH 120 II goes much further: Its internal DSP allows for room calibration via Neumann’s revolutionary Automatic Monitor Alignment. MA 1 (sold separately) makes sure your DSP powered monitors are optimally adapted to the character of your room and perfectly aligned for your listening position. Even in acoustically treated rooms, this results in a significant improvement.
Tonal compatibility with other KH line studio monitors makes it possible to use the KH 120 II in mixed setups e.g. in immersive setups. For flexible connectivity the KH 120 II features both analog and S/PDIF inputs.
Additionally, the KH 120 II AES67 model variant offers integrated redundant AES67 audio network ports that are fully compliant with broadcast standards such as ST 2110, ST 2022-7 redundancy, and RAVENNA. At the same time, the KH 120 II AES67 is compatible with DANTE®-generated AES67 network streams.
Neumann engineers took great care to develop a patent pending amplifier technology which combines superior audio performance with the energy efficiency of Class D. Although the power amplifiers of the KH 120 II deliver up to 145 W to the 5.25” woofer and 100 W to the 1” tweeter, they only consume 17 W at idle. Auto-standby reduces power consumption to 0.3 W when the KH 120 II has not been used for a while, but can be deactivated.
The KH 120 II is available in two color options, anthracite and white.
