Neumann KH120A Powered Studio Monitor Speaker

The KH 120 is a two-way bi-amplified monitor with thermally protected class-AB amplifiers (80 W each.) Just like the drivers, its Mathematically Modeled Dispersion™ (MMD™) waveguide is calculated with an optimal level of precision. Sound distributed in a horizontally precise manner ensures flexibility in the listening position; the narrower vertical dispersion reduces the negative effects of nearby reflections – for example from a desk or mixing console. The finely controlled dispersion characteristics optimize reproduction in even the most varied of room configurations.

Features:

• Low-distortion, high-frequency reproduction
• Elliptical Mathematically Modeled Dispersion (MMD) waveguide offers smoother off-axis response
• Long throw bass driver
• Two-color and dimmable Neumann logo displays operation status and activation of the extensive protection system
• Robust metal grille
• Large front panel ports reduce bass compression and make it easier to mount the monitor in tight spaces
• Compact, durable aluminum cabinet minimizes resonances and offers better heat dissipation
• Wide horizontal dispersion and narrow vertical dispersion for greater control at the mixing console
• Powerful analog amplifiers with large headroom
• 4-position bass, low-mid and treble acoustical controls offer more control in diverse acoustical environments
• Wide range input gain and output level controls for easier interfacing with signal sources
