CI-150 Installation Guide
Thank you for purchasing the Phase Technology CI-150 high definition in-wall speaker system. Each pair of the CI-150
makes an LCR configuration. There is no need for a separate center channel speaker. This is done by combining the
output of each CI-150’s center channel speaker. By running both lower speakers from the center channel output on your
amplifier the content sounds like it is coming from the center of the TV screen. Because of this, special consideration
must be taken to run two sets of speaker leads to each CI-150. One will be connected to the left (or right) channel on your
amplifier and the other will be used on each CI-150 for the center channel. When you are ready to connect the speaker
leads to your amplifier you will have a set of leads for the left and right channel and TWO sets of leads for the center
channel.
The mounting frame on the CI-150 is made of extruded aluminum and has a uniquely designed self-aligning clamping
system to secure the flange assembly to the drywall. This patented design simplifies installation and reduces unwanted
wall vibration resulting in improved performance and definition.
Getting Started
For an efficient installation you will need the following tools:
Electric screwdriver (drill) with philips bit
Drywall saw or knife
Tape
measure
Bubble
level
Stud-finder
Pencil
3/32” standard screwdriver
When selecting the speaker mounting location, it is prudent to take a few extra minutes to carefully inspect and measure
the wall or ceiling area where you intend to mount the CI-150. An inspection of the room or rooms that back-up to the
wall you have selected for mounting the CI-150, can often alert you to potential obstacles. For example, if the wall you
want to mount into happens to be the common wall for a bathroom or kitchen, there is a good chance you will encounter
water or sewer pipes in the wall that will not be detected by a stud-finder. An electronic stud-finder is a useful tool to
assist you in selecting the speaker placement, however be cautious as they often give false readings. Drilling a ½”
inspection hole will save you time and eliminate the need for elaborate drywall repair. If you are unable to see into the
hole, use a stiff piece of wire or coat hanger with a right angle bend 5” – 6” from one end. Insert the wire into the
inspection hole and spin in all directions. If you do not hit any obstructions, such as wood or pipes, it is usually safe to
proceed. If any obstructions are detected, an alternate location should be selected. You will want to center the speaker
equidistant between studs when possible – if your mounting position places the speaker flange close to a stud, you may
remove the clamp assembly on that side and secure the flange directly to the stud using drywall or wood screws.
Step 1
Place the cutout template against the wall surface and align it using your bubble level. Hold, tape or staple the template in
place and trace around the perimeter of the template with a pencil. Remove the template and begin cutting on the pencil
line.
Step 2
When the cutout is complete, carefully remove the drywall piece from the opening. You now have a large opening to
facilitate pulling your speaker wire. We recommend 16 gauge or heavier wire be used with the CI-150. Contact your
Phase Technology Dealer for a recommendation.
Step 3
Remove the grill from the CI-150 using the pull tabs and unscrew the eight screws that secure the speaker baffle to the
aluminum frame assembly and set aside. Remove the flange assembly from the back box.
Step 4
Next loosen the screws used to tighten the clamp assembly until they are fully extended. To place the flange assembly
into the wall push the clamp assemblies toward the center of the flange opening; the holes in the flange will allow the
mounting screws to tilt toward the center opening enough to insert the flange assembly into the wall. Insert the right side
into the wall cutout and slide the complete assembly to the right. This will enable you to then fit the left side clamp
assembly into the cutout. Center the entire assembly in the opening.
