Neumann KH 810 II

While it is designed to handle complex multichannel setups up to 7.1.4, it works perfectly in a standard 2.1 stereo configuration. Its advanced bass management allows you to integrate it seamlessly with your existing studio monitors regardless of the channel count.

The KH 810 II features integrated DSP, which handles precise room alignment internally. While you can use Neumann's MA 1 alignment microphone system for automated calibration, the subwoofer's onboard processing is designed to handle the heavy lifting of room correction without needing constant external software intervention.

The KH 810 II reaches down to 16 Hz, which is deep enough to reproduce the lowest audible frequencies accurately. Despite its 10-inch driver size, the long-throw engineering and Extremely Linear Force Factor technology allow it to maintain high sound pressure levels with very low distortion, making it suitable for most professional studio spaces.

The unit is highly versatile, offering both analog and digital connectivity. You can connect via standard analog XLR, DB25, or digital AES3 (BNC), and it also supports redundant AES67 audio network connectivity for modern IP-based studio infrastructures.

Weighing in at 56.2 lbs, it is substantial but manageable for most studio floors. It does not require special structural reinforcement, but given its performance, you should ensure it is placed on a stable, vibration-free surface to maintain the accuracy of its low-frequency output.
