LOUDSPEAKER SYSTEMS:
Today’s requirements for audio-
phile listening in the home environ-
ment place a high premium on
stereophonic imaging, and the
S2600 and S3100 systems, like the
Project Everest DD55000 system
before them, provide accurate
stereo soundstage imaging over a
wide listening area. At the same
time, the systems, with their horn
loaded high frequency section, can
deliver high acoustic output with
very low distortion.

PLACEMENT AND ADJUSTMENT:
JBL believes that the most
accurate stereo soundstaging will
normally take place when the
included angle between loudspeak-
ers and the listener is in the range
from 40 to 60 degrees, as shown in
Figure 1. In most listening spaces,
this translates into a loudspeaker-
to-loudspeaker distance of 2 to 3
meters, with the listener located at
a similar distance from the line con-
necting the loudspeakers. This will
normally take place when the
included angle between loudspeak-
ers and the listener is in the range
from 40 to 60 degrees, as shown in
Figure 1. In most listening spaces,
this translates into a loudspeaker-
to-loudspeaker distance of 2 to 3
meters, with the listener located at
a similar distance from the line con-
necting the loudspeakers. This will
result in a nominal listening angle of
about 53 degrees. The listener may
then move closer or farther away to
adjust the angle to taste.
about 53 degrees. The listener may
then move closer or farther away to
adjust the angle to taste.
In the condition we have
described here, place the loud-
speakers so that their baffles are
parallel to the wall behind them.
The exact placement is not critical.
Corner placement works well, since
the controlled radiation from the
systems will cause minimal reflec-
tion from the adjacent wall.

If you choose to operate the
loudspeakers in a larger room with
greater spacing between them, it
may be necessary to angle them in
slightly (perhaps not more than 5 to
10 degrees) to achieve the desired
image stability over a wide listening
range.

Begin the setup procedure by
putting on a recording that has a
strong phantom center image.
(Most solo vocal recordings will sat-
isfy this requirement.) As you are
sitting in the middle, equidistant
from the loudspeakers, you should
hear a strong, unambiguous center
image. Take time here to adjust bal-
ance, if necessary. Then, as you
move slightly to one side, the
image should remain clearly cen-
tered.
