New Construction and Retrofit Installations
Note: A new construction rough-in kit and back box kit are optionally
available from Atlantic Technology. Please refer to the instructions included
in those kits for their use. If the rough in kit has been used please go directly
to Step 2 below.
1
Cut an appropriately sized opening in the ceiling material. Be sure that the
ceiling material can support the weight of the speaker. Also be sure that
the sides of the opening are at least 1 ½ inches away from any beams or
joists within the cavity. If it is not, the rotating clamps will be restricted
in their movement and may not clamp properly.
2
Be sure that all foreign material in the ceiling is kept out of the speaker
assembly, particularly the back of the woofer cone. There is a cloth shield
on the rear of the woofer, but please use care anyway.
3
Mount the white frame in the ceiling. Using the red arrows on the frame
as a guide (see Figure 2), roughly orient the frame towards the listening
area. This will assure that the woofer is aimed correctly at the listener.
Remember: This is not critical. An approximate orientation is fine, since
the 6 LCR’s tweeter—which can be precisely adjusted—carries most of
the directional information.
4
Tighten the mounting screws one at a time. As you tighten the screws,
the clamps on the back of the assembly will turn and lower, grabbing
the back of the ceiling and sandwiching the ceiling between themselves
and the frame’s circular trim ring.
5
Snug all four mounting screws in this manner. Be careful not to overtighten
them.
6
You may now install the grille into the frame by gently pushing it into the
recess and paint the ceiling and the grill/frame assemblies at the same
time to assure a neat, uniform appearance.
7
(If you have painted the grill/frame assembly, remove the grille from
the frame with a pick or awl.) Attach the previously installed audio feed
wires to the speaker terminals. Simply remove 1/2 inch of insulation from
the end of each input wire. Push down on the terminal connector and a
large opening will appear in the shaft of the connector that is capable of
holding up to 10 gauge wire. Insert the bare wire into the opening and
release the terminal. Be sure to observe correct polarity, connecting the
positive (+) leads to the red terminals and the negative (-) leads to the
black terminals. Also be sure that no stray strands of wire touch across
any terminals.
8
Screw the black driver/crossover assembly into the white frame housing
so the woofer points in the direction you selected. The screw bosses are
“keyed” for easy attachment.
9
IMPORTANT: After aiming the tweeter at the listening location, use the
high frequency level adjustment, located on the tweeter assembly, to
increase (+)or decrease (–) the level of high frequency sound produced
by the tweeter. See Figure 6.
