Neumann’s Flagship Sub for Immersive-format Systems
Designed for no-compromise immersive-format monitoring setups, the mighty KH 870 II assumes the flagship position at the top of Neumann’s active subwoofer line. Spec’d for up to 7.1.4-channel bass management, the KH 870 II packs dual 10-inch drivers, prodigious power, and high SPL handling into a robust enclosure that’s easy to position optimally, thanks to Neumann’s advanced DSP control features. Ideal for large, world-class music control rooms and post-production mix theaters, the KH 870 II supplies the headroom and precision that top-level projects require.
Note: For studios needing to integrate their monitoring system into an AoIP network, the KH 870 II is also available with a built-in AES67 interface (model KH 870 II AES67). Contact your Sweetwater Sales Engineer for more information.

Max headroom
Today’s motion picture soundtracks and multichannel music mixes place tremendous demands on a monitoring system in terms of dynamic range and low-frequency extension, and subwoofers are the key to handling such program material with unerring accuracy and composure. Designed for maximum headroom, the KH 870 II effortlessly delivers LFE channel information down to 18Hz, mating perfectly with high-performance main monitors such as Neumann’s KH 420 to render uncompressed, full-frequency immersive audio formats such as Dolby Atmos without a hint of stress.


High-performance design
The Neumann KH 870 II powered sub sports a pair of 10-inch drivers along with eight channels of all-analog connectivity to integrate smoothly into modern studios, with 4-mode LFE-channel processing, fourth-order crossovers, and onboard controls to fine-tune your sub's sound to perfection. Neumann's Low Resonance Integral Molding materials make for an inert cabinet with zero resonances and distortion, while the two Neumann-designed long-throw bass drivers and high-capacity reflex ports cut down on compression while offering lightning-fast transient response.
Neumann: the first name in professional microphones and monitors
In 1928, Georg Neumann founded the company that bears his name and introduced the first mass-produced condenser microphone. Ever since, the Neumann badge has stood for unwavering quality. Neumann’s instantly recognizable diamond is more than a corporate logo — it is a quality seal. Every microphone and monitoring system that bears it is a testimony to this proud tradition. As you ponder your future in recording, we’d like to leave you with a Sweetwater tip that, interestingly, has nothing to do with sound. If you have clients coming into your studio, appearances matter — and having no-name microphones set up in your tracking room is probably not the best way to impress them. When your clients see the Neumann badge, they’ll know they’re in a professional studio with serious equipment. The presence of Neumann microphones commands instant respect. They’re classics that tell the world: you’ve arrived.
