Renewing the drivers, amplifier and DSP is just the beginning of the story. As one would expect, the Neumann KH 150 provides an exceptionally flat frequency response from 39Hz to 21kHz (±3 dB), being designed for all applications from broadcast to music production. And although they remain a nearfield model, the KH 150 is able to meet the expectations of contemporary music styles that require a powerful, deep low-end and/or elevated listening levels such as urban music, EDM, and film scoring.
"The KH 150 closes the gap between the KH 120 and the KH 310, but it does far more than that", explains Portfolio Manager Stephan Mauer. "Its internal DSP engine offers many benefits such as a phase linearized crossover and a new level in tonal consistency. The KH 150 is made to extremely low tolerances of no more than ±0.8dB! And you can hear it, too: Stereo imaging is razor-sharp."
Digital electronics also allows the KH 150 to be calibrated via Neumann’s MA 1 Automatic Monitor Alignment (sold separately). "The KH 150 follows the same philosophy as all Neumann studio monitors: highest linearity, lowest distortion, no coloration, and perfect adaptability to any acoustic environment," states Neumann’s CEO Ralf Oehl. "In our pursuit of sonic perfection, we not only optimize every parameter of the loudspeaker itself, we also include the greatest variable: the listening environment. The KH 150’s DSP engine perfectly integrates with Neumann’s game-changing MA 1 Automatic Monitor Alignment for best possible sound in any room."
In addition, the KH 150 is extremely energy efficient. 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 KH 150’s amplifiers deliver up to 145W to the 6.5" woofer and 100W to the 1" tweeter, it goes down to 17W when in idle mode. Auto-standby reduces power consumption to 0.3W when the KH 150 has not been used for a while, but can be deactivated.
Another interesting aspect is the connectivity. The KH 150 offers analog and digital inputs (S/PDIF) and will also be available in an AES67 variant with 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 150 AES67 models will be compatible with Dante-generated AES67 network streams.
The KH 150 (US $1750 / EUR 1650 ) and KH 150 AES67 (US $1999 / EUR 1895) active monitors will be available in September 2022.
