Thank you for purchasing Phase Technology CI custom
installation speakers. This eighth generation of high
performance in-wall models features the same superb
sonic performance as our acclaimed PC-Series cabinet
speakers in addition to great exibility and easy installa­tion, thanks to Phase Tech’s patented QuickMount™
tool-free clamping system. The most striking change to the
series VIII is a new look with the o-axis tweeter design.
This feature maximizes the speaker’s clarity and imaging by
creating an asymmetrical loading or diraction pattern,
reducing the amount of diraction normally caused by a
ange-to-wall junction. The net result is the best sonic

realism you can buy in an in-wall. All CI-Series speakers include
self-resetting solid-state PTC protection circuits. This unique
system is able to detect when the speaker is being over-driven
and lowers the speaker volume until the problem is corrected.
The PTC device then resets itself for normal operation. Other
features include liquid-cooled tweeters for greater power
handling, moisture-resistant materials in all of the critical
speaker components, galvanized steel speaker grilles and
stainless steel hardware for improved corrosion resistance, IR
knockout mounts and tweeter level controls.

1. Choose the appropriate mounting
location for each speaker.

2. Remove the speaker and ange/grille
assemblies from their boxes. Using the
supplied cutout template, carefully mark
the area to be cut out. Using a drywall
knife or saw, cut the hole in the drywall
and prepare the speaker wires for
connection to the speaker terminals. Use
a level to insure that the ange is square.

3. Remove the grille from the
mounting ange by pressing it from
behind. Attach the provided white
gasket material to the outside, rear
edge of the ange. Insert the
mounting ange into the hole with
the end marked “TOP” facing up.
Loosen the ange clamping screws
one turn (counter clockwise) to
release the clamp. Next tighten all 4
ange clamp screws evenly to secure
the ange to the wall. It is best to
tighten each screw with the same
amount of force (torque).
CAUTION: Do not over tighten.

7. Tighten down the four QM clamps
by pressing them down ush with the
bae’s surface.

6. Insert the bae into the mounting
ange, aligning QM clamps with the
four QM posts. Also make sure that the
tweeter is placed at the end of the
ange marked “TOP”.

4. Use the provided tool to fully open
the four Quick Mount™ (QM) clamps. If
the tool is not available a small screw
driver can be used.

NOTE – When deciding upon a location
consider the following:

• Be certain your speaker wires can be run to
or are accessible from these locations.

• Make certain the wall or ceiling material is
sturdy enough to support the weight and
vibration of the speakers.

• It is recommended that our pre­construction rough in brackets (part number
RB-18) be used whenever possible in new
construction.

• Be certain the area behind the speaker is
free of obstacles such as wall studs, electrical
wiring, pipes, etc.

• Each speaker should be positioned
properly relative to the listening area for good
coverage.

• Audio performance and room-to-room
isolation will be improved if there is some
berglass insulation placed loosely behind the
speaker.

8. Using some familiar source material,
listen to the tweeter’s balance with the
level control in each of its three
positions to nd your favorite.

9. Carefully install grille by pressing it
into the gap between the ange and
the bae and enjoy your new Phase
Technology CI speakers.

5. Connect the speaker wires to the
spring loaded input terminals on rear
of speaker, making sure no loose
strands are exposed.
