Lay the positioning yoke on the ground so that the hole
closest to the front of the yoke is aligned with the
3
/4”
threaded rigging hole on both sides of the SB-1
.
Place the split washer on the
3
/4” grade rigging bolt and
then place the flat washer on top of split washer so that the
split washer is closest to the bolt head. Hand thread the
bolt-washer assembly through the yoke and into the
3
/4”
hole on both sides of the SB-1.
Use a 1
1
/16 hex-socket wrench to tighten the bolt. Use
approximately 40 to 60 foot pounds of torque to tighten to
the bolts sufficiently so that the SB-1 will not shift on the
yoke as it is lifted off the ground.
When the bolts are tight, stand the SB-1 on its yoke. To
remove the positioning yoke, reverse this process.
The hanging method:
On the top of the SB-1 is a single rigging point which can
be used to hang the SB-1 for easy yoke installation and
removal.
Connect the rigging hardware to the rigging plate.
Hang the SB-1 so that the weight of the speaker is
supported by the rigging hardware.
With the speaker suspended the yoke can be easily
removed or installed on the speaker.
