KH 150
Studio Monitor
From Neumann:
The KH 150 is a powerful bi-amplified studio monitor with reference-class performance. Its 6.5” woofer in a bass reflex cabinet provides stunning low end and high SPL capability with undiminished clarity. DSP controlled electronics ensure linear phase response and allow for room-adaptive calibration via Neumann’s revolutionary MA 1 Automatic Monitor Alignment.
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. It allows you to hear every nuance of your tracks. Mixing becomes so much faster and easier, once the guesswork is over. And more creative, too: Sounds genius, but can I get away with that? Is that vocal bright or sibilant? Is it too much bass? The KH 150 will tell you. Honestly.
What differentiates the KH 150 from its smaller siblings is its deeper bass response down to 39 Hz. That’s almost as low as the larger KH 310, thanks to the KH 150’s novel 6.5” high-precision woofer in a carefully designed bass reflex cabinet. The KH 150 is thus ideally suited to urban music, EDM, film scoring, and all styles that require extended low end and/or elevated listening levels. Thanks to powerful amplifiers (145 W/100 W) and sophisticated protection limiters, no clarity is lost even at high SPLs. But, being a true universalist, the KH 150 works just as well for everything from rock to classical music, broadcast applications and voice-over work.
