3. INSTALLATION
Step 1. Loosen one each of the screws on both
sides of the speaker, then remove the
baffle. 
You can remove the baffle by loosening
the screw without taking it out.
Step 2. Install the cabinet on the wall.
The cabinet has knockout holes (ø20.5 mm or ø0.81") for cable routing.
Remove the desired knockout hole depending on the wiring method, and route cables.
2-1. When installing the cabinet on the wall using the hanging holes:
(1) Fix 2 supplied screws (tapping screws 4 x 16)
to the wall leaving about 5 mm (0.2") space
from the wall surface.
(2) Remove the cabinet's knockout, then run the
cables routed from the wall through this hole.
In the case of exposed wiring, fit the supplied
rubber grommet into the knockout hole.
Note: Cut a hole in the grommet's thin
membrane to match the cable size.
(3) Hook the cabinet onto the stick-out screws,
then tighten the screws.
Tip: The shape of cabinet's hanging hole is
so designed to prevent the cabinet from
falling easily even if an outward force is
applied to.
2-2. When installing the cabinet on the wall using other holes:
(1) Remove the cabinet's knockout, then run
the cables routed from the wall through this
hole.
In the case of exposed wiring, fit the supplied
rubber grommet into the knockout hole.
Note: Cut a hole in the grommet's thin
membrane to match the cable size.
(2) Install the cabinet on the wall using the
mounting holes [a], [b] or [c] shown at right. 
Note: Since no mounting screws are
supplied with the speaker, separately
prepare them appropriate for the
construction of wall and its thickness.
2-3. When mounting the cabinet into the wall:
(1) Make a mounting hole of 260 x 175 mm
(10.24" x 6.89") in the wall.
(2) Remove the cabinet's knockout hole, run
the cables through this hole, then install
the cabinet using 4 supplied screws
(tapping screw 4 x 16).
Fit the supplied rubber grommet into the
knockout hole.
Note: Cut a hole in the grommet's thin
membrane to match the cable size.
