Next make sure that the clamps are positioned inside the

the frame of the speaker.

5.25" Two Way In-Ceilling

With the grill removed, place the speaker in the ceiling

opening. Make sure that the speaker wire is not hanging

against the speaker where it can vibrate and rattle as the

speaker reproduces your audio program.

Next, one at a time, turn

each of the three 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 ceiling surface.

Tighten all four of the mounting screws in the same

manner until the speaker is properly aligned and held

tight to the ceiling surface.

Painting the Speaker

Two paint shields are included in each AC Series

speaker package. Place the paint shield inside the

frames to protect the speakers. You can now safely

paint the speaker frames 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.

Caution: Do not over tighten!

Removing the AC Series Speaker

Should it ever become necessary to remove the AC

Series speaker from the ceiling, simply remove the

grill and turn the four mounting screws counter-

clockwise until you feel the clamps lock out of position

in their resting flanges. The speaker should easily come

out of the wall for service or replacement.

Grill Removal (if installed)

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 6).

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 a

loss of high frequency content in the audio signal.

To prevent sonic degradation in your AC Series

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.
