SF 10C SUB • Installation 8
2. At the location where the subwoofer is to be installed, remove as many ceiling tiles as
necessary to install the subwoofer.
NOTE: The number of tiles to remove depends on the height of the structural
ceiling above the suspended ceiling, given the 10-degree spread from the
subwoofer to the structural ceiling.
At an approximate angle of 10 degrees out from each corner of
where the subwoofer will be installed, mark and drill four holes in the
structural ceiling for the suspension cable anchors.
3. Screw a lag eye bolt (or an appropriate anchor) into each hole.
4. Thread the loose end of the suspension cable through the bolt eyehole,
pass the loose end of the cable through the looped end and tighten.
Allow each cable to hang.
Suspend the main subwoofer enclosure from the ceiling
ATTENTION:
The SF 10C SUB is heavy, approximately 38 pounds (17 kg), and bulky.
ATTENTION : La SF 10C SUB est lourde, et pèse environ 17 kg (38 livres), et est
volumineuse.
• Use at least two people to install the subwoofer; one person to lift the unit into
position
AND to hold it, the second person to fasten the suspension cables.
• Il faut au minimum deux personnes pour installer le caisson de grave ; la première
pour mettre l’unité en place
ET la tenir, et la seconde pour raccorder les câbles de
suspension.
• Consider using a scissor-lift or other lifting apparatus rather than a ladder to work
in the ceiling.
•
Songez à utiliser une nacelle élévatrice ou tout équipement similaire plutôt qu’une
échelle pour travailler au plafond.
• Do not rest the subwoofer on the ceiling grid, even temporarily.
• Ne posez pas le caisson de grave sur la grille de plafond, même temporairement.
TIP: If a scissor-lift is not available, the speaker can be hoisted using the suspension
cables.
1. Remove the grommets from all four corners of the subwoofer frame (see figure 4 on
the next page).
2. Install the included eyebolts into the four holes on the four corners of the subwoofer
frame. Secure the eyebolts in place with the provided locking nuts (
figure 4 ).
3.
With the help of at least one other person, carefully lift the subwoofer enclosure into the
installation location.
4. Holding a cable gripper, pass the loose end of one of the cables down through one hole
of the gripper. Ensure that about 12 to 15 inches (30 to 38 cm) of cable has exited the
gripper (
figure 4 ).
