Professional studios demand precision at every frequency, and the KH870 subwoofer rises to meet those exacting standards with its sophisticated 7.1 High Definition Bass Manager™. This bypassable bass management system provides remarkable flexibility, supporting everything from mono recordings through to cutting-edge 7.1 HD formats. Eight analogue channels ensure seamless interconnectivity in modern studio environments, while four-mode LFE-channel processing maintains compatibility across all professional formats and industry standards.
The KH870's technical specifications reflect Neumann's commitment to accuracy and control. Fourth-order crossovers work alongside flexible acoustical controls to integrate smoothly into existing systems, whilst built-in volume control and hardware remote functionality provide centralised system management independent of your source equipment. The electronics can be remotely located to minimise cabling complexity, making the KH870 adaptable to configurations ranging from mono setups through to immersive 3D audio environments.
Advanced amplifier technology combines with premium acoustical components to reproduce low frequencies with exceptional fidelity. Robust drivers housed in a rock-solid cabinet work with carefully engineered ports to produce tight, articulate bass reproduction without distortion, even at demanding playback levels. The innovative Plane Wave Bass Array™ (PWBA™) sum output technique improves lateral consistency throughout the listening area, whilst frequency response extends down to an impressive 18 Hz.
Designed to complement Neumann's comprehensive monitor range, the KH870 functions superbly as a standalone unit or can be daisy-chained for larger systems requiring higher SPL capabilities. Its front-mounted port design allows flexible placement options, including wall-adjacent positioning or flush wall mounting. The subwoofer suits music production, broadcast, and post-production facilities for tracking, mixing, and mastering applications, integrating seamlessly with other Neumann loudspeakers in multichannel configurations.
