Active subwoofer with a unique bypassable 2.1/0.1 bass management and four LFE routing modes. It is the perfect complement for the KH 80 DSP, KH120 and KH 310 speakers.

The Neumann KH 870 is an active subwoofer with two 10 inch woofers, 7.1 high-definition bass manager and provides the perfect complement to the Neumann range of studio monitors.

The Neumann KH 870 includes eight analogue channels to allow for connection of up to 7 satellites and four LFE modes to ensure compatibility across all surround formats up to 7.1. It features fourth-order crossovers and flexible acoustical controls to ensure perfect integration to any system.

The two drivers are powered by two powerful amplifier and use high-quality components to provide a tight and articulate sound with distortion-free low-frequency reproduction all the way down to 18Hz even at high replay levels. The Sum output provides Plane Wave Bass Array techniques to improve lateral consistency within the sweet spot. 

The KH 870 is the ideal complement to Neumann’s range of studio monitors including the KH 120, KH 310 and KH 420 and can be daisy-chained to larger multi-channel systems with higher SPL.
