3. Complete the pre-wiring to the speaker brackets before the drywall goes up. Leave an extra few feet of speaker wire on each end
to make your life easier later. Coil the excess and tack it carefully to an adjacent ceiling joist for easy retrieval during speaker installa-
tion. You can be clever here.
4. During the drywall installation, cut a hole in the drywall so it butts up to the protruding lip of the mounting bracket, as you would
cut out for a ceiling light can. (Once installed, the lip of the speaker frame will extend about ½ inch beyond the perimeter of the
bracket lip to hide minor imperfections in the cutout.) (fig.3).
5. After the ceiling trim work is installed and the painting is complete, but just before the carpet or flooring is installed install the
speaker by first connecting the speaker wire to the spring posts on the back of the speaker assembly, making sure to observe correct
polarity – red (+), black (-).
6. The speaker assembly is then inserted into the hole in the bracket and attaches to the bracket and ceiling drywall via four plastic,
spring-loaded mounting clamps (dog-legs) on the back of the speaker assembly that will swivel out 45˚ and lower to “sandwich” the
drywall (and mounting bracket) when you start to tighten the 4 mounting screws (fig.4). Begin this phase by being sure the dog-legs
are rotated sideways (like the speaker came packed) so that the body of the speaker assembly can slide through the mounting brack-
et. Exercise caution not to damage the drivers themselves.
