By Nigel Redmon • January 5, 2012 The new Neumann KH 810 active subwoofer (larger front and rear views below) Following the debut of the KH 120 two-way active nearfield monitor last fall, Neumann has announced the launch of the KH 810 and KH 870 active subwoofers. Both feature the company’s 7.1 High Definition Bass Management technology, which complements high-definition video with accurate sound reproduction. Bass Management is compatible with all formats, from mono to the latest 7.1 high definition systems such as Blu-ray. Eight electronically balanced analog XLR inputs ensure flexible interconnectivity. Four-mode LFE channel processing provides compatibility across all formats, while 4th order crossovers and flexible acoustic controls allow for convenient system integration. A built-in volume control permits centralized system adjustment of replay levels, independent of the source. The electronics can be located remotely to reduce cabling, and to allow the cabinet to be mounted flush to a wall. The KH 810 can be used either as a subwoofer dedicated to reproducing the LFE channel, or as a means of providing low frequency extension with an increased maximum SPL. With the KH 810, it is now possible to assemble flexible monitoring systems for studios of different sizes, with a smooth, uniform response that ranges from below 20 Hz to above 20 kHz. The self-powered system includes a 10-inch driver, solid cabinet, and carefully designed ports for tight, articulate low frequency reproduction down to 18 Hz. By using sum output, Plane Wave Bass Array (PWBA) techniques can acoustically improve lateral consistency in the listening area and further increase low frequency linearity. The flexibility of the system is further enhanced a range of accessories. The KH 810 ($1,999) and the KH 870 ($3,199) are available from select retailers.
