Stacking a PL-LA12 to a PL-SUB18
It is possible to stack a PL-LA12 on a PL-SUB18 directly without the use of an Array Frame. Angles that are achievable on the first box
will be b5° up-tilt to -12.5° down-tilt according to the position of the Straight Link at the front and the slider at the back.
NOTE:
The GLL used for simulation in EASE or EASE Focus from AFMG will only allow the standard configuration, which
is [0 / -12.5°].

NOTE: Remove the side panels from each side of the PL-LA loudspeaker.
1. Attach two Straight Links to the front slots of the PL-SUB18 loudspeaker. Use the central hole of the link as shown in Figure 11. With
the link in this position, the FLY setting will result in a 0°angle. On the 0.5°, the down-tilt angle will be -12.5°.
NOTE: Using the two extreme holes of the link will result in a shift of 5° up : up-tilt of +5° on the FLY position, 0° when in
the 8° position and down-tilt of -7.5° on the 0.5°position.
2. Attach two Y-Links to the middle slots of the PL-SUB18 subwoofer. The nuts should be located inside the PL-LA12 loudspeaker.
3. Place PL-LA12 loudspeaker upside down on top of the PL-SUB18 subwoofer.
4. Bolt the front attachment point of the PL-LA12 loudspeaker (do not torque yet) to the PL-SUB18 subwoofer.
5. Bolt the back attachment point of the PL-LA12 loudspeaker (do not torque yet) to the PL-SUB18 subwoofer.
6. Adjust the angle using the slide bar (remove the blocking screw, adjust the slider, put back the blocking screw on the nut labeled
with the desired angle value).
7. Torque to 11.3 N∙m (100 lbf∙in) with the bolts provided.
8. Attach the side panel.
