SONANCE SYMPHONY ® T
PAINTING THE SPEAKERS
All Sonance Symphony speakers come from the factory fitted with a plastic ‘paint
plug’ that protects the speaker drivers while the mounting flange is being painted.
Paint the grille separately from the speaker. Before painting, carefully remove the
under-grille cloth. It is held in place with a light tacking glue that makes it easy
to remove. Spray the grilles with thinned paint (5 parts thinner to 1 part paint),
being careful not to plug the holes. Too heavy a coat of paint on the grille will
adversely affect the sound of the speaker.
Once the grilles and flange are painted and dry, replace the under-grille cloth,
remove the paint plug from the mounting flange and install the grille.
SPEAKER ADJUSTMENTS
Pivoting Tweeter
All Symphony T-series speakers (except the S621T) have a pivoting tweeter that
allows you to direct sound towards or away from the listening area, depending on
how the speakers are being used:
• If you’re using the speakers in stereo or as the front left/center/right speakers
in a home theater, pivot the tweeter directly towards the listening area. This will
help the sound from the speakers blend into
a solid soundstage 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 pointing the tweeters towards a
wall or window, away from the listeners.
To Pivot the Tweeter:
Apply light pressure to the plastic ring around
the outside edge of the tweeter dome, as
shown in Figure 9 . Do not touch or apply pressure to the tweeter dome.
Tweeter Level Control
The S625
T
, S624
T
and S623
T
have a tweeter level control switch (see Figure 10 )
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.
