Neumann KH 870 II AES67 Dual 10" Powered Subwoofer With DSP & AoIP Interface

Need bass management built for today’s networked studios? The Neumann KH 870 II AES67 dual 10" powered subwoofer with DSP and AoIP interface pushes the boundaries of modern studio bass management. With its dual 10" long-throw woofers featuring Extremely Linear Force Factor (ELFF) technology, this sub delivers clean, deep extension down to 16Hz. Advanced DSP control ensures precision and flexibility for stereo, surround, and immersive setups up to 7.1.4. Engineers working in music, post-production, or broadcast can use the KH 870 II AES67 to connect up to 11 monitors via analog, AES3, or redundant AES67 audio over IP, integrating full bass management and room correction. The cabinet’s rigid build and acoustic isolation make it suitable for studios where reliability and sonic accuracy matter.

Advanced Neumann DSP Delivers Precise Bass Management

Think of DSP as the system’s brain for low-end accuracy. Digital signal processing in this subwoofer shapes low-frequency response and aligns phase across large monitor arrays. The DSP manages crossover, delay, and output calibration for up to 11 connected monitors. Use the MA 1 Automatic Monitor Alignment software (sold separately) to integrate analog and DSP-equipped speakers for full system room correction. Precise DSP means engineers can trust the bass to translate across systems and formats, from stereo mixes to immersive audio.

Neumann Dual ELFF Drivers Deliver Clean Low End

Dual 10" drivers provide more headroom and authority for large monitoring spaces. Each woofer uses Extremely Linear Force Factor (ELFF) technology to move air with minimal distortion, even at high volumes. Damping of breakup modes and an optimized basket design keep harmonic distortion low, supporting accurate low-frequency playback down to 16Hz. The rigid grille protects the drivers from impact, while the bass reflex cabinet design eliminates unwanted port noise—ensuring every detail of the mix is audible.

Flexible Neumann Connectivity for Multichannel and AoIP

Modern studios need versatile hookups that cover every format. Multiple connection options make the KH 870 II AES67 subwoofer easy to integrate. Two analog XLR inputs and outputs support stereo operation, while Sub D25 connectors and seven AES3 digital outputs (BNC) cover multichannel setups. AES67 network ports provide redundant audio over IP links, compliant with broadcast standards like ST 2110 and Dante-generated AES67 streams. The unit acts as a hub, distributing up to 12 network channels and routing audio to all attached monitors.

Neumann User-Focused Controls Streamline Setup

Fast setup is essential in demanding studio workflows. Accessible switches on the sub let engineers select operational modes and calibration sources—either manual or via network software. The system’s ground lift, high common-mode rejection, and symmetrical signal flow reduce electrical noise in complex studio environments. Control functions and status indicators make configuration fast and accurate, minimizing setup time and errors in busy production workflows.

Neumann Cabinet Construction Minimizes Resonance

Cabinet design matters when chasing clean, focused bass. The subwoofer’s ultra-stiff wooden cabinet resists vibrations and includes built-in rubber feet for acoustic isolation. Its painted finish and robust grille protect the drivers from physical damage, especially in studios with high traffic. Internal damping and tuned bass reflex engineering eliminate standing waves and port noise, keeping bass tight and focused. Every structural detail supports reliable performance over long sessions.

Engineer Experience With Neumann KH 870 II AES67

Confidence in the low end is critical for modern mixing. Studio professionals building immersive systems or managing complex bass setups will use this dual-driver subwoofer to achieve accurate, low-distortion bass. With easy integration, robust hardware, and DSP control, users can expand existing monitor arrays or upgrade to networked audio without workflow headaches. The KH 870 II AES67 delivers precision and flexibility, letting engineers create mixes that translate reliably in every listening space.
