SF 10C SUB • Installation 15
NOTE:
For installation in rigid vs. soft material:
• Rigid material — Three locking arm screws use
built-in Opti-Torque indicator rings that snap and
separate from their plastic rings when the screws
are tightened to the correct torque. The indicator
ring falls down the screwdriver shaft. When
this occurs, stop tightening the screw to avoid
overtightening the locking arms to the C-ring (see
the figure at right).
•
Soft material
— Because fiberglass ceilings and
other soft materials are not as rigid as mineral tiles
and other hard materials, the Opti-Torque indicator
should
not
be used as a tightening guide due to the risk of overtightening. See
the
ATTENTION
below.
ATTENTION:
•
To avoid damaging or deforming soft ceiling material, tighten the locking arms
to secure the grille adapter, but short of causing the grille adapter to deform
the flat mounting surface of the ceiling.

• Afin de ne pas endommager ni altérer un plafond souple, serrez les bras de
verrouillage pour sécuriser l’adaptateur en grille, en veillant cependant à ce
que l’unité ne cause l’altération de la surface de montage plane du plafond,
comme illustré ci-dessous.
8.
Affix the metal grille to the magnetic grille adapter.
9. Adjust the position of the subwoofer relative to the installation so that the subwoofer
appears level to the critical eye and is centered over the grille.
Ensure that the port
tube is as close as possible to the installation surface without touching it .
NOTE: Do not allow the port tube or any part of the subwoofer to touch the
installation surface. Undesired audio vibrations can occur.
