The Neumann KH 870 Active Studio Subwoofer is compatiblewith all standard consumer formats from mono through to the latest7.1 HD systems thanks to the use of the 7.1 High DefinitionBassManager system.

The Neumann KH 870 subwoofer is designed to complement ourextensive range of monitors, and can be used on its own, ordaisy-chained to make larger systems capable of higher SPL. The KH870 can be used in music, broadcast, and post production studiosfor tracking, mixing, and mastering. The cabinet can be positionednext to a wall or flush mounted into a wall due to the frontmounted port.

Eight channels of analog or an optional 8-channel, 24-bit, 192kHz digital input card ensures flexible interconnectivity formodern studios. Four-mode LFE-channel processing guaranteescompatibility across all formats and industries. Forth-ordercrossovers and flexible acoustical controls allow for seamlesssystem integration. Built-in volume control and a hardware remotecontrol allows for centralized system control independent of thesource, and the electronics can be remote located to reducecabling.

The latest amplifier technology and acoustical components havebeen used to ensure the most accurate sound reproduction possible.Robust drivers, a rock-solid cabinet, and carefully designed portsguarantee a tight, articulate, and distortion-free low frequencyreproduction, even at high replay levels. Using the sum output,Plane Wave Bass Array (PWBA) techniques acoustically improveslateral consistency in the listening area. The Bass extends down to18 Hz.
