The Neumann KH 810 + KH 870
As consumer technology advances at ever
faster rates, professional technology increasingly finds itself trying to keep up. An example
of this is the advent of the Blu-ray and other
high definition formats that have increased the
audio channel count to 7.1 and beyond.
The KH 810/KH 870 are an answer to these new
demands by offering a new 7.1 High Definition
Bass Manager™. This is 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

The latest amplifier technology and acoustical
components have been used to ensure the most
accurate sound reproduction possible. Robust
10” 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.
The KH 810/KH 870 subwoofer are designed to
complement our 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/KH 870 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 our range.
