STEP 4: Mounting Dog Ear
Tighten the dog-ear brackets by simply turning the screws on the
slowly clockwise. The quick-turn mounting system and frame will
"sandwich" or clamp around the wall to hold the speaker securely in
place. (See Diagram 4)
STEP 1: Cutout Tracing
Trace along the inclusive template. Cut along the traced line using a
drywall saw or rotary drill. A simple, inexpensive drywall saw (about
$10 at your local hardware store) is the best choice for beginners.
Caution: This is the most important part of the entire installation.
If you are not certain whether any obstructions exist behind the
desired mounting area, you should start by cutting a small hole in
the center of your penciled mounting hole with a drywall saw. Use a
piece of sandpaper to sand down the cut out edge for a smoother
contour. (See Diagram 1 )
Run the cable into the cut out location while leaving an extra two
feet to make the connection to the speaker easier. Strip back
approximately ½ inch of the speaker cable insulation and twist
the copper wires tightly for easy insertion.
On the back of the speaker, press down on the gold-plated
compression terminal to reveal the "eye" and insert the speaker
cable through the eye for secure connection. Release the compres-
sion terminal to lock each cable securely. (See Diagram 2)
STEP 3: Tweeter Adjustment
Your in-ceiling speakers come from the factory with the tweeter facing
response. However, you can adjust the tweeter to focus the sound at
your listening location. In order to do this, gently press on the grill (See
Diagram 3). Caution: Do not touch the tweeter dome while adjusting for
your hearing preference. (See Diagram 3) -Pivoting Tweeter Model Only
