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.

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

wall

” of 0.8 to 2 m from the wall behind

the loudspeaker. When positioning bass managed loudspeakers, avoid a distance “d

wall

”

of 0.8 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 ec-

tions.

Copy the diagram “Installation angles” that can be found at the end of this operating manual.

Place the diagram at the listening position or center of the listening area.

Using a tape measure, place the loudspeakers at the same distance from the center of the

diagram “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 di erences > 1 cm (

") by delaying closer loudspeakers by 30 µs/cm

(76 µs/inch).

If you are using the KH 120 D:

Use the DELAY rotary switches E to compensate for distance di erences (see page 14).

The DELAY rotary switches E allow for corrections with a resolution of 3.44 cm

(13/8"), any small remaining time-of-ﬂ ight adjustment should be made by moving

the loudspeaker cabinet.

KH 120 D

Check the location of the loudspeaker cabinet. This depends on the application:

• 2.0 systems (stereo): ±30°, plus optional subwoofer(s)

• 5.1 systems:

ITU-R BS.775-1: 0°, ±30°, ±110° (±10°), plus optional subwoofer(s)

(center, front left/right, surround left/right)

ANSI/SMPTE 202M: 0°, ±22.5°, arrays to the surround left and to the surround right,

plus optional subwoofer(s)

• 7.1 systems: 0°, ±30°, ±90°, ±150°, plus optional subwoofer(s)

(center, front left/right, side left/right, back left/right)

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.

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.
