PAINTING THE SPEAKERS AND GRILLES

You can paint the speakers and grilles before installing them, which will
eliminate the “paint scar” if the speaker ever needs to be removed for 
service. You can also paint the speakers after installation, but before the
grilles are attached. All QR-Series speakers come from the factory fitted
with a plastic ‘paint plug’. Use the paint plug to protect the speaker 
drivers while the flange is being painted along with the wall.

Sonance always suggests painting 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 speaker flange and install the grille.

PIVOTING THE 522

QR

TWEETER

The 522

QR

has a pivoting tweeter that allows you to direct sound toward

or away from the listening area.

If you’re using the speakers in stereo or as the front L/C/R speakers in a
home theater, you should pivot the tweeter directly towards the listening
area. This can be especially helpful if the speakers are widely-separated
and the music fails to blend into a central sonic image.

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
tweeters towards a wall or window, away from the listeners.

To pivot the tweeter:

Apply light pressure on the oval plastic tweeter mounting ring, as shown
in Illustration 3.

Note: Do not touch or apply pressure to the tweeter dome.
