The Neumann KH 150 is an active two-way studio monitor that takes the next step forward for Neumanns speaker design. The KH 150 delivers an utterly flat frequency response with a maximum variance of 0.8 dB for staggering consistency so you can trust whatever you hear from it. This speakers DSP helps to create this consistent flat response while also delivering advanced digital crossovers that eliminate phase distortion. The KH 150s Mathematically Modeled Dispersion (MMD) waveguiding prevents reflections from your studios desk and gives it a broad sweet spot that sounds great anywhere in your studio. Adjustable response switches to boost bass treble or mids help you tailor this monitors sound for your ears and its compatibility with Neumanns MA 1 monitor alignment system calibrates its response for your room. Finally the KH 150 also delivers a brand new amplifier design that combines the efficiency of Class D amplification with improved sound quality with 245 W power consumption when in use and 17 W when idle. Innovative DSP The KH 150 takes advantage of modern DSP to help shape and define its sound into one of the most accurate monitors youll ever hear. A flat and linear DSP-tuned frequency response with incredible consistency of no more than ± 0.8 dB variance ensures you will only ever hear the truth of any signal you run through it. Then advanced digital crossover filters prevent phase distortion for an utterly clean and uncoloured sound with broad clear stereo imaging. The final form of DSP present is compatibility with Neumanns MA 1 speaker calibration system that will help adapt the KH 150s tuning for your room creating a perfectly optimised sound. Accurate Sound Acting as a bridge between Neumanns KH 120 and KH 310 monitors the 150 provide deep clear bass with incredible linearity down to 39 Hz thanks to its 6.5″ woofer design and bass reflex enclosure. Paired with its DSP-attenuated tuning and distortion-free projection the KH 150 is excellent for all kinds of precision audio work. From music production mixing film scoring broadcast and voiceover work the accuracy of these studio monitors will adapt to any material you throw at them. Efficient Amplification Neumann have re-approached their amplifier design to combine the incredible efficiency of Class D amplification with custom circuitry that improves sound quality. As a result the KH 150 will draw up to 245 W peak power while drawing 17 W when idle. Plus its auto-standby mode reduces power consumption to 0.3 W when not in use.
