Neumann KH 805 II

The Neumann KH 805 II is a premium DSP-controlled active studio subwoofer designed for precise, distortion-free low-frequency reproduction down to 16 Hz. Featuring a newly developed 10-inch ELFF™ long-throw driver, advanced DSP processing, integrated 2.0/2.1 bass management, and MA 1 Automatic Monitor Alignment compatibility, it delivers exceptional bass accuracy and seamless integration into professional stereo monitoring systems.

The Neumann KH 805 II is a next-generation active studio subwoofer engineered to provide reference-quality low-frequency monitoring for professional recording, mixing, mastering, and broadcast environments. Combining advanced DSP technology with a newly developed 10-inch long-throw woofer, the KH 805 II extends low-frequency performance down to an impressive 16 Hz while maintaining the accuracy, clarity, and low distortion expected from a Neumann monitoring system.

At the core of the KH 805 II is Neumann's innovative ELFF™ (Extremely Linear Force Factor) driver technology. Designed to maintain exceptional linearity even at high excursion levels, the 10-inch woofer delivers powerful bass response with minimal harmonic distortion and outstanding transient accuracy. The result is a precise and controlled low-frequency foundation that reveals critical mix details without coloration.

The integrated DSP engine transforms the KH 805 II into the central hub of a modern stereo monitoring system. Optimized for 2.0 and 2.1 configurations, its advanced bass management system provides seamless crossover integration between the subwoofer and connected monitors. Full compatibility with Neumann's MA 1 Automatic Monitor Alignment software enables automatic room correction, phase alignment, and acoustic optimization for superior monitoring accuracy in any environment.

One of the KH 805 II's most valuable features is its ability to bring modern DSP-based room correction to existing analog monitoring systems. Connected analog Neumann monitors can benefit from advanced digital crossover optimization and room alignment, effectively upgrading traditional setups to contemporary monitoring standards without replacing existing speakers.

The subwoofer's ultra-rigid wooden enclosure is specifically engineered to suppress resonance and standing waves while minimizing group delay. Combined with front-facing ports and extensive internal damping, the cabinet contributes to the subwoofer's tight, accurate, and highly controlled bass response.

Professional connectivity includes balanced XLR analog inputs and outputs, as well as AES3 digital audio connectivity via BNC connectors, making the KH 805 II suitable for both traditional and modern studio infrastructures.
