SPEAKER ADJUSTMENTS
Pivoting Woofer
The Symphony S623SSTR, S621sstr and SRS1 mocels have a pivoting woofer assem-
bly. These pivoting drivers allow you to direct sound toward or away from the
listening area, depending on how the speakers are being used:
• Pivoting the woofer towards the listening position will maximize the speaker’s
clarity and definition.
• If you’re using the speakers as surround channel speakers in a home theater,
you can create a more diffuse, spacious surround effect by aiming the woofers
towards a wall or window,
away from the listeners.
To pivot the woofer, apply
pressure on the outer edge
of the tweeter support brack-
et, as shown in
Figure 7
.Do
not touch or apply pressure
to the woofer cone.
To Pivot the Woofer:
Apply pressure on the outer
edge of the tweeter support
bracket, as shown in
Figure 8
. Do not touch or
apply pressure to the woofer
cone.
Tweeter Level Control
The S623SSTR has a tweeter level
control switch (see
Figure 8
) that lets
you boost or cut the tweeter’s level by
3dB. This allows you to adjust the
speaker’s brightness to better match
your listening room or personal taste.
Once you have installed the speakers,
listen to a variety of music that you
are familiar with. If the music all
tends to sound too bright or dull, use
the Tweeter Level Control to compensate. If some recordings sound dull and some
sound bright the speaker is accurately reproducing differences in the recordings,
and you should leave the control in the middle (0dB) position.
