    Neumann KH 870 G – Studio subwoofer per sistemi 7.1

    MORE POWER. SAME PRECISION.

    The KH 870 is an answer to the demands by offering a 7.1 High Definition Bass Manager™. The flexibility of this bypassable 7.1 bass manager means it is also compatible with all standard consumer formats from mono through to the latest 7.1 HD systems.

    Eight channels of analog ensures flexible interconnectivity for modern studios. Four-mode LFE-channel processing guarantees compatibility across all formats and industries. Forth-order crossovers and flexible acoustical controls allow for seamless system integration. Built-in volume control and a hardware remote control allows for centralized system control independent of the source, and the electronics can be remote located to reduce cabling. From Mono to 3D, there are uses for the KH 870 in many different system configurations.

    IMPROVING LATERAL CONSISTENCY

    The latest amplifier technology and acoustical components have been used to ensure the most accurate sound reproduction possible. Robust drivers, a rock-solid cabinet, and carefully designed ports guarantee a tight, articulate, and distortion-free low frequency reproduction, even at high replay levels. Using the sum output, Plane Wave Bass Array™ (PWBA™) techniques acoustically improves lateral consistency in the listening area. The bass extends down to 18 Hz.

    FLEXIBLE MOUNTING OPTIONS

    The KH 870 subwoofer is designed to complement Neumann’s extensive range of monitors, and can be used on its own, or daisy-chained to make larger systems capable of higher SPL. The KH 810 can be used in music, broadcast, and post production studios for tracking, mixing, and mastering. The cabinet can be positioned next to a wall or flush mounted into a wall due to the front mounted port, and can be mixed freely in multichannel systems with other loudspeakers from Neumann’s range.
