Neumann KH 810 II AES67 Reference Quality DSP-Controlled Subwoofer with Multichannel Bass Management & AoIP Interface

Next Generation Subwoofer

The KH 810 II AES67 advances its predecessor with enhanced acoustic precision and additional capabilities. Featuring an innovative 10” long-throw woofer equipped with Extremely Linear Force Factor (ELFF™) technology and smart protection limiters, it delivers remarkably low distortion even at peak sound pressure levels.

The KH 810 II AES67 expands low-frequency response down to 16 Hz and provides nearly double the output capacity of the KH 750 DSP. This makes it an ideal partner for mid-sized monitors like the KH 150 and KH 310.

The KH 810 II AES67 features DSP control for exceptional audio performance and integrates seamlessly with the MA 1 Automatic Monitor Alignment system (sold separately). When paired with analog Neumann monitors like the KH 120 A (now discontinued), KH 310, or KH 420, it provides sufficient DSP processing to calibrate entire stereo, surround, or immersive setups up to 7.1.4 channels using MA 1, optimizing both frequency response and phase coherence. It also complements Neumann’s latest DSP-equipped monitors perfectly. For surround and immersive configurations, both analog and DSP models can be combined and room-aligned via MA 1 with the Multichannel Extension (sold separately). This makes the KH 810 II AES67 far more than a subwoofer—it is an essential tool for upgrading or expanding existing systems with immersive audio capabilities..

Equipped with redundant AES67 connectivity, this subwoofer offers a comprehensive solution for integrating your entire speaker system into an Audio over IP network. The KH 810 II AES67 can receive up to 12 channels of network audio, delivering playback through the subwoofer and supporting up to 11 studio monitors connected via its analog and digital outputs.

Precision in Every Detail

Since subwoofers are usually positioned on the floor, the driver is safeguarded by a sturdy grille to prevent accidental damage. The solid cabinet incorporates a precisely engineered bass reflex system designed to deliver tight, accurate bass with port noise that remains inaudible.

The subwoofer provides two analog XLR inputs and outputs for stereo connectivity. For multichannel setups, the KH 810 II AES67 includes two Sub D25 connectors for analog connections and seven AES3 digital outputs (BNC) capable of supporting up to 11 studio monitors. All analog inputs and outputs are electronically balanced, while the AES3 BNC outputs are compatible with Neumann monitors featuring S/P-DIF inputs when used with a BNC to RCA adapter cable.

Equipped with two network ports, the KH 810 II AES67 provides redundant AES67 audio-over-IP connectivity supporting up to 12 input channels. It functions as a hub, receiving multichannel audio and distributing it throughout the system via analog or AES3 (BNC) outputs to up to 11 additional speakers, incorporating its internal bass management.

The KH 810 II AES67 is ideal for music, film scoring, broadcast, and post-production environments, supporting tasks from tracking to mixing and mastering. Featuring an innovative power amplifier design, it delivers exceptional audio quality alongside high energy efficiency. The Auto Standby function can be disabled via the MA 1 app for greater control.
