Powerful Bass Extension for Immersive Systems The KH 810 II is the perfect subwoofer for medium sized rooms, providing bass extension with Neumann precision. It includes a unique and flexible Bass Manager for stereo, surround and immersive systems up to 7.1.4. Analog and digital outputs provide flexible connectivity to up to 11 studio monitors.Next Generation Subwoofer The KH810II improves on its predecessor in acoustic performance and adds new features. Thanks to a novel long-throw 10 woofer with Extremely Linear Force Factor (ELFF) technology and intelligent protection limiters, the KH810II ensures exceptionally low distortion even at maximum SPLs.The KH810II extends low frequency reproduction down to 16 Hz and delivers about twice the output of the KH 750 DSP. This makes the KH 810 II the perfect complement to mid-sized speakers such as the KH 150 and KH 310.The KH810II is DSP-controlled for superior sonic performance and seamless integration via MA1 Automatic Monitor Alignment (sold separately). When combined with analog Neumann studio monitors such as the KH 120 A (discontinued), KH 310, or KH 420, it offers sufficient DSP-power for aligning an entire stereo, surround or even immersive system up to 7.1.4 via MA 1, optimizing not only the frequency response but also the phase. Of course, the KH810 II is also a perfect complement to Neumanns DSP-equipped studio monitors. In surround and immersive systems, analog and DSP-equipped Neumann speakers can be combined and room-aligned using MA 1 with Multichannel Extension (sold separately). The KH 810 II is therefore much more than just a subwoofer: It is the perfect tool for upgrading existing systems and/or extending them for immersive audio.Precision in Every Detail As subwoofers are typically placed on the floor, a robust grille protects the driver from accidental damage. The rigid cabinet features a highly efficient bass reflex system, which is carefully engineered and tuned for the tightest bass reproduction with inaudible port noise.Two analog XLR inputs and outputs are available to connect the subwoofer for stereo operation. For multichannel operation, the KH 810 II offers two Sub D25 connectors for up to 12 analog input channels and another two Sub D25 connectors for up to 11 analog output channels. All inputs and outputs are electronically balanced. Studio monitors can also be connected digitally via AES3 (BNC). For audio networking, this subwoofer is also available as an AES67 variant, the KH 810 II AES67.The KH 810 II excels in music, film scoring, broadcast, and post-production studios for tracking, mixing, and mastering. Thanks to a novel power amp design, the KH 810 II combines superior audio performance with excellent energy efficiency. Its Auto Standby function can be deactivated in the MA 1 app.Main Features:Deep and powerful bass down to 16 HzThe perfect complement to mid-size Neumann KH line studio monitorsDSP-controlled for superior sonics and unparalleled precisionRoom correction via MA 1 Automatic Monitor Alignment (sold separately)Supports automatic alignment also for analog KH-line studio monitors (patented)
