CI-110 II Installation Guide
Thank you for purchasing the Phase Technology CI-110 II high definition in-wall speaker system. The mounting frame of
extruded aluminum has a uniquely designed self-aligning clamping system to secure the flange assembly to the drywall.
This patent pending 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-110 II. An inspection of the room or rooms that back-up to the
wall you have selected for mounting the CI-110 II, 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 to 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
The CI-110 II uses the same cutout template as the CI-110 and CI100. The cutout opening is 20 1/2” X 8 7/8”. 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-110 II. Contact your
Phase Technology Dealer for a recommendation.
Step 3
We recommend a piece of fiberglass insulation for maximum performance. It is available from your local home center.
Be careful not to overstuff the cutout – one piece the length of the opening will be adequate.
Step 4
Carefully remove the speaker baffle from the aluminum frame assembly and set aside. Remove the flange assembly from
the packing carton. The flange assembly must make a good seal to insure maximum performance. You will find two L-
shaped foam gasket pieces in the bottom of the carton. Peel the removable tape from the gasket and stick the adhesive
side to the backside of the flange. Upon installation of the flange assembly gasket will contact the front wall surface to
form an airtight seal.
Step 5
When you remove the flange assembly from the packing carton, you will notice the screws used to retain the clamp
assembly 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
