Note: You can adjust the torque applied to the
RotoLock screws to achieve a proper grille fit.
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 422MR 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.
