Position the base of each speaker equi-
distant from your ideal listening loca-
tion. Y ou can use a tape measure,
string, or thread to gauge the distance
from your chair to each speaker. Use
the center of the back or seat of your
chair as one reference point and the
inner edge of each speaker as the other.
You can have an assistant at your chair
hold one end of the tape or string while
you check the distance to each speaker.
Equidistant inner corners
If you don't have an assistant, you can use a pin to hold the end of the string
by sticking the pin in the center or back of your chair and tying the string or
thread to it. The anchor point must be solid and stable to get accurate
measurements!
Next, adjust each speaker so it is point-
ed directly at your chair. Although you
can do this by obtaining identical mea-
surements to both lower corners of
each speaker, an easier and more
precise way to do this is to observe the
reflection of a flashlight in the ESL
diaphragms. Hold the flashlight just
above your head while you search for
its reflection.
Center your reflection
Get your reflection in both speakers centered from side-to-side while
sitting in your listening chair. To avoid altering the previous measure-
ment, pivot the speakers on their inner corners — the one you used as the
reference point.
When your reflection is centered side-to-side in both speakers, check to see
that it is at the same height in both speakers. It doesn't have to be centered
from top to bottom, but the reflection of your ears should be at least a foot
from the bottom edge of the ESL. If not, the rear foot of the speaker can
be screwed in or out to adjust the vertical angle of the speaker.
the speakers should now be correctly positioned, but it is a good idea to
double-check by measuring from your chair to your reflection in each
speaker's electrostatic cell.
Sanders' speakers are deliberately made
to be directional so that the sound
quality is the most realistic possible. It
is three-dimens
ional and has a
“holographic” quality.
Wide-dispersion speakers send most of
their sound away from you into the
room where it reflects off room surfaces
before reaching you. You are actually
listening to the room more than the
speakers. B ecause t
hese reflections
travel varying dis
tances before they
reach you, they are delayed by varying
amounts. When the speaker produces
a transient sound (and music is mostly
transient in nature), you hear the sound
from many directions and at slightly
differ
ent times. T his “smears” the
transient and produces “muddy” sound
and a poor image.
Sanders' speakers direct the sound
directly to you instead of throughout the
room. You hear the speaker instead of
the room
. T his is why Sanders'
speakers sou
nd more clear than even
very good conventional speakers.
Sound clarity and image quality is a
function of timing and distance. So to
get the best performance, you will need
to get your speakers precisely posi-
tioned. T his requires that you have
b
oth speakers an equal distance from
you and that they are pointed directly at
you. To avoid reflections from the wall
behind you, it is best that your listening
chair be well-away from the wall or that
the wall has an absorbent surface in the
area directly behind your head.
This may seem like extra effort that is
unique to Sanders' speakers, but this is
not true. All speak
ers perform best
when they are accurately posi
tioned.
Because wide-dispersion speakers
confuse the sound from the speakers
with the sound from the room, they are
incapable of producing high-quality
images. T herefore, errors in position-
ing are not as obvious as with Sanders'
speakers.
