Neumann KH 810 II: next-generation subwoofer for modern studios

Neumann KH 810 II combines exceptional bass extension with "smart" system management, becoming much more than just a subwoofer. Designed for medium-sized rooms, it is the ideal complement to monitors such as the KH 150 and KH 310, moving the system toward truly full-range monitoring with typical Neumann precision.

Deepest bass and absolute control

The KH 810 II extends the response down to 16 Hz, offering deep but always controlled low-end. The 10" long-throw woofer with ELFF™ (Extremely Linear Force Factor) technology and intelligent protection limiters keep distortion extremely low even at high sound pressure levels, with very little group delay and minimized cabinet resonances.

Integrated Bass Manager: the heart of stereo, surround and immersive systems

The real highlight is the extremely flexible Bass Manager, designed to handle configurations up to 7.1.4. With dedicated routing and I/O you can connect and manage up to 11 monitors, turning the KH 810 II into the perfect hub to upgrade existing setups and take them to multichannel and immersive audio.

DSP and MA 1: System integration and alignment.

Internal DSP enables superior performance and rapid integration via MA 1 Automatic Monitor Alignment. In conjunction with analog Neumann monitors (e.g., KH 120 A, KH 310, KH 420), DSP power can align entire multichannel systems, optimizing frequency response and phase for the listening point. A solution designed for music production, post, broadcast, tracking, mixing and mastering.

Professional construction and studio reliability

The ultra-rigid wood cabinet with self-damping properties, durable finish, built-in rubber feet and protective grille make the KH 810 II ready for everyday studio use. The high-efficiency bass reflex is optimized for maximum accuracy with inaudible port noise, while thermal protectors and limiters (soft clip/excursion) preserve drivers and electronics over time.
