SONANCE SYMPHONY
®
TR & TSQ
• If you’re using the speakers in stereo or as the front left/center/right speakers
in a home theater, pivot the woofer and/or tweeter directly towards the listen-
ing area. This will help the sound from the speakers blend into a solid sound-
stage even if the speakers are widely separated.
• 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
and/or tweeters towards a wall or window, away from the listeners.
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.
To Pivot the
Tweeter:
Apply light pressure to
the plastic ring around
the outside edge of
the tweeter dome, as
shown in Figure 8. Do not touch or apply pressure to the tweeter dome.
Tweeter Level Control
The S625TR, S624TR, S623TR and
S623
TSQ
have a tweeter level control
switch (see
Figure 9
) 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 compen-
sate. If some recordings sound dull and some sound bright the speaker is accu-
rately reproducing differences in the recordings, and you should leave the control
in the middle (0dB) position.
