Looking to power your studio with bass that feels as big as your ideas? The Neumann KH 870 II dual 10" powered subwoofer with DSP brings precision bass and advanced control to larger studios and immersive audio setups. This subwoofer uses two custom 10" drivers powered by the ELFF (Extremely Linear Force Factor) system for deep, punchy bass down to 16Hz. DSP management ensures each note stays accurate, no matter how loud you push the system. With flexible connectivity, the KH 870 II supports up to 7.1.4 multichannel configurations—connecting to both analog and digital studio monitors. For tracking, mixing, and mastering in music, film, or broadcast, this unit delivers reference-grade performance and easy integration. Its tough cabinet and smart design keep bass tight and clean, even at high volume.
Neumann DSP-Controlled Bass Management Extends Output
Think of DSP as the KH 870 II’s control center for the low end. DSP control lets the KH 870 II manage low frequencies with greater accuracy. The built-in Bass Manager balances output across stereo, surround, and immersive systems up to 7.1.4. By using Neumann’s MA 1 Automatic Monitor Alignment (sold separately), the subwoofer and connected monitors can be tuned for room acoustics. This tight alignment produces clear, powerful bass that never overwhelms the mix, giving engineers full confidence when mixing for film or music.
Neumann Dual ELFF Drivers Reduce Distortion
Two long-throw 10" woofers, designed in-house, use ELFF technology for linear movement and low distortion. The drivers’ resonance-optimized baskets and robust grilles help them handle high output without warping or breaking up. Tight control and low harmonic distortion at high SPL mean mixes sound clear and accurate, even during intense tracking or playback sessions.
Flexible Neumann Connectivity Supports Large Setups
Modern studios demand flexible connection paths. Connections on the KH 870 II include stereo XLR inputs and outputs, plus Sub D25 ports for up to 12 analog channels in and 11 out. Digital AES3 (BNC) outputs make it easy to link the subwoofer to digital studio gear. Audio networking with the AES67 variant supports advanced control and remote alignment. The unit’s layout streamlines setup for studios with multiple monitors, letting users daisy chain for subwoofer arrays or connect to networked systems for large-scale production.
Neumann Cabinet Construction Preserves Sound Integrity
The cabinet uses ultra-stiff wood with an acoustic isolation finish and built-in rubber feet. Internal damping keeps standing wave resonance at bay, while the bass reflex system reduces group delay for tighter output. The design prevents accidental damage and minimizes vibration transfer, so bass stays clean and defined even in demanding studio environments.
Engineer Experience With Neumann KH 870 II
Engineers working on music, film, or post-production can count on this subwoofer for reliable bass extension. The KH 870 II supports complex surround and immersive mixes, letting users focus on sound—not setup headaches. Every feature helps users deliver mixes that translate, offering clean low end and accurate response for confident decisions in the studio.
