Tighten all six of the mounting screws in the same
manner until the speaker is properly aligned and held
tight to the wall surface. Caution: Do not over tighten!
Aiming the Tweeter
Carefully place your fingertips at the plastic edges of
the tweeter housing.
Using gentle pressure, swivel the tweeter to aim the axis
of the tweeter toward the listening area. You can use a
piece of music with a solid center-imaged vocalist to
assist in correctly aiming the tweeter. When the
tweeters are properly aligned, you will hear a coherent
and stable center image from your listening position.
Usually, it is sufficient to aim the tweeter only as it
handles the frequencies that control the direction of
individual sounds in your audio program material.
Next make sure that the clamps are positioned inside the
frame of the speaker.
With the grill removed, place the speaker in the wall
opening. Make sure that the speaker wire is not hanging
against the speaker where it can vibrate and rattle as the
speaker reproduces your music.
Next, one at a time, turn each of the six screws that
operate the clamps counter clockwise a few turns until
you feel the clamp is loose from its resting position.
Now turn the screw clockwise until you feel the clamp
contact the wall surface.
Recommended Speaker Wire Gauges
The resistance of the speaker wire in your installation
can cause your speakers to perform at less than their
optimum quality level. Excess resistance caused by
using an undersized speaker wire can result in loss
of detail and definition in the bass region of your audio
program, as well as loss of dynamic range. Over
extremely long wire runs you may even experience
loss of high frequency content in the audio signal.
50’ or less - 16 Gauge 2-Cond. CL3 Rated
50’ - 150’ - 12 Gauge 2-Cond. CL3 Rated
150’ - 200’ - 10 Gauge 2-Cond. CL3 Rated
To prevent sonic degradation in your
AC515W speaker
installation, total speaker wire resistance should be
kept below 0.5 ohms. The following table lists
recommended speaker wire gauge versus wire run
length.
Painting the Speaker
A paint shield is included in each AC515W speaker
package. Place the paint shield inside the frame to
protect the speaker. You can now safely paint the
speaker frame to match your wall surface if you desire.
When painting the grill caution should be taken to
ensure that paint does not clog or congest the perforated
openings in the grill. This would prevent proper operation
of the grill by restricting the airflow from the individual
drivers in the speaker.
Removing the AC515W Speaker
Should it ever become necessary to remove the AC515W
speaker from the wall, simply remove the grill and turn
the six mounting screws counter-clockwise until you
feel the clamps lock out of position in their resting
flange. The speaker should easily come out of the
wall for service or replacement.
Locate a small hook tool
(available at most auto parts
stores or home improvement
shops, resembling a dentist’s
pick- a bent paper clip or
stiff wire will work as well),
hook the metal mesh of the
grill near a corner or edge
and gently pull it towards you.
Only lift the grill 1/4" (6mm)
at this location. Move the tool
1-2" (25-50mm) and repeat
until the grill can be removed
without damaging it (Figure 7).
