minimum of 10 feet (3.0 meters) away from the loudspeakers.
Align the speakers to point directly at your listening position.
Slowly open them outward until you get the best soundstage
without losing too much center-stage definition. For most
cases, the left tweeter should point toward your left shoulder
and the right tweeter should point toward your right shoulder.
This setup should give good results in most common situations.
Should they need further adjustment follow these next
guidelines. Moving the speakers closer to the front wall will
mainly increase the bottom-end. Changing the spacing
between each speaker will primarily affect the width, height,
depth and center of acoustic-image. The Sarastro can be placed
fairly close to the side wall without much problems
Should they get closer to the side wall, the boundary
reenforcement will increase the bass. Opening them will
improve your image width and closing them will improve your
image center definition. Conversely, if you wish to broaden
your listening area, tow them inward even more until they are
aligned with your opposite shoulder. Always move the speaker
step by step. For each step, search for a uniform tonal balance,
a good width, height and depth of the acoustic image and a
well-defined center stage. Improvement of a sonic feature
frequently deteriorates another. Try moving the speakers in the
direction that appears to give a better overall improvement. It
is sometime a long process that needs perseverance and
assiduity. But your efforts will be well rewarded.
Room Treatment
The Sarastro gives its best performance in an average-furnished
domestic listening room. It requires a minimum of room
treatment. Before investing in room treatment we strongly
recommend you to take the time to listen and get familiar with
your speakers. The Sarastro has proved to be a standalone
loudspeaker that rarely needs to be acoustically corrected. A
good room placement is usually the most effective approach.
You should always start to position your speakers without any
treatment. If speaker positioning cannot solve standing waves
or reverberation problems read the following.
The principal design factor for internal acoustics of a room, in
addition to shape and size, is the control of sound absorption
and reflection. The total absorption required to give optimum
reverberation is inherent to your room characteristics, i.e.,
which surfaces are absorptive or reflective, the area of these
surfaces and the selection of acoustical materials.
A
flutter echo
is a rapid (usually regular) succession of
reflected pulses resulting from a single pulse. They can be
easily identified by clapping your hands while walking in the
room. They are frequently located at the ceiling corners or at
the center of the ceiling-wall intersections. If flutter echos are
prominent, please consult your dealer to get proper assistance
on that matter.
