Neumann KH 805 II – Reference 10" DSP Subwoofer for Studio Monitoring
The Neumann KH 805 II is a next-generation professional subwoofer, designed to deliver extended low-frequency reproduction down to 16 Hz with exceptional accuracy. Powered by DSP, it ensures reliable sound reproduction, perfect alignment via the MA 1 Automatic Monitor Alignment system (sold separately), and optimal integration with KH series monitors. With flexible stereo bass management and increased power, it is the ideal companion for Neumann KH 150 and KH 310 monitors, as well as for surround and immersive systems.
Equipped with a 10’’ long-excursion woofer using Neumann’s proprietary Extremely Linear Force Factor™ (ELFF™) technology, the KH 805 II delivers powerful, precise bass with extremely low distortion, even at high sound pressure levels. Its ultra-rigid cabinet and optimized bass-reflex system eliminate resonances and ensure faithful low-end reproduction. This subwoofer offers about twice the power of the KH 750 DSP, opening new possibilities for mixing, mastering, and post-production.
Featuring balanced analog inputs and outputs, as well as digital AES3/S-PDIF connectivity, the KH 805 II integrates seamlessly into the most demanding studio environments. Compatibility with the MA 1 software enables precise alignment even with analog KH series monitors, optimizing frequency and phase response. Robust, versatile, and highly accurate, it is an indispensable tool for music, broadcast, and post-production studios.
