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 care-
ful 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
The Merlot 422
MR
speaker has a pivoting tweeter that allows you
to direct sound towards or away from the listening area, depend-
ing on how the speakers are being used: 
• If you’re using the speakers in stereo or as the front left/cen-
ter/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 sur-
round effect by pivoting the
tweeters towards a wall or
window, away from the lis-
teners.
To Pivot the Tweeter:
Apply light pressure to the
plastic ring around the outside
edge of the tweeter dome, as
shown in 
Figure 7. Take care
not to touch or apply pressure
to the tweeter dome itself.
