mounting the Subwoofer Using the Yoke
The yoke can be used to mount the subwoofer either on a vertical surface, like a wall, or from an overhead surface, like
a ceiling or ceiling beams. In either case, the attachment points on the enclosure for securing the yoke are the same. The
yoke is designed to attach to only two sides of the cabinet and cannot be attached to any other surfaces. The yoke features
slots to allow for either maximum rotation of the cabinet, or for minimum separation between the cabinet and the mounting
surface. Consult the following illustrations.
Once the subwoofer is secured in position, the QSC logo can be rotated if desired. If the logo is difficult to rotate the first
time, a tool may be required. A small flat-head screw driver is recommended. Gently work the tool between the logo badge
and the grille to allow rotation. Exercise care to avoid scratching the grille surface.
the yoke must be secured to structure that is capable of supporting the weight of the subwoofer and
must be connected using load rated hardware.
Consult a licensed, professional engineer when any doubt or questions arise regarding a physical
equipment installation.
1 - Remove the screws from the selected attachment points using a #2 phillips-head screw driver or electric driver. Remove
only the two screws that will be used for the attachment of the yoke.
DO NOt REmOVE ANY OtHER SCREWS.
If a
screw hole is left open, it will create an airleak which will cause noise and compromise the performance of the cabinet.
2 - Remove the adhesive backing from the rubber pad and attach the pad to the cabinet by pressing the adhesive coated
side against the cabinet. Make sure not to obstruct the attachment holes. The adhesive will hold the pad in place as you
mount the enclosure to the yoke.
3 - Align the yoke with the attachment points on the subwoofer and place the attachment hardware according to the il-
lustration.
4 - Tighten the hex-head/phillips-head bolts enough to hold the subwoofer in place but loose enough to rotate with minimum
force. Check the alignment of the subwoofer for best desired appearance. As long as the port is not blocked, the alignment
of the subwoofer will not affect performance. Once positioned, tighten the bolts so that the subwoofer will not rotate with
force.

It is recommended that the yoke be attached to the mounting surface prior to attaching the yoke to the subwoofer enclo-
sure. The yoke is designed to allow attachment to the mounting surface with mounting points ranging from 5.5 in (140 mm)
to 6.5 in (165 mm) apart.
