Positioning The Loudspeakers - Neumann.Berlin KH 120 Manuel Utilisateur

Positioning the loudspeakers

Carry out the following steps very accurately, since the more accurate the physical arrange-
ment of the loudspeakers in the room, the more accurate the reproduction will be at the
listening position.
Distances Observe the recommended distances between the loudspeakers and your listening position
(imperial dimensions are approximate):
• Minimum: 0.75 m (2.5')
• Recommended: 1.0–2.0 m (3'–6')
• Maximum: 4.0 m (12')
Avoid positioning the loudspeaker at a distance "d
loudspeaker. When positioning bass managed loudspeakers, avoid a distance "d
to 1 m from a solid wall behind the loudspeaker. Similarly, avoid these distances from solid
side walls or a solid ceiling. Respecting these positioning limitations reduces the chances of
dips in the low frequency response (comb fi ltering) caused by strong refl ections.

at an angle
Using a tape measure, place the loudspeakers at the same distance from the center of the dia-
gram "Installation angles". To ensure good imaging, do this at an accuracy of at least 1 cm (
If the loudspeakers cannot be placed at the same distance from the listening position, com-
pensate for distance diff erences > 1 cm (
(76 µs/inch).
At the same time, check the location of the loudspeaker cabinet. This depends on the appli-
cation:
• 2.0 systems (stereo):
• 5.1 systems:

ANSI/SMPTE 202M:
• 7.1 systems:
The acoustical axis of the KH 120 is located at the midpoint of the bass and tweeter drivers.
Always point the acoustical axis, in the horizontal and vertical planes, towards the listening
position.
x = 9.1 cm
y = 17.0 cm
The acoustical axis is a line perpendicular to the loudspeaker's front panel along which
the microphone was placed when tuning the loudspeaker's crossover during design.
Pointing the acoustical axis, in the horizontal and vertical planes, towards the listening
position or center of the monitoring area will give the best measured and perceived
sound quality.
Position the loudspeaker so that there is a direct line of sight from the listening position to
the bass and tweeter drivers.
