PROFICIENT C1075s Signature 10 Inch Ceiling LCR Speaker
WARNING: To avoid possible injury, the PCB-C1000 Mounting Bracket must be used with the C1075s speaker for both new construction and retrofit installations. The included mounting bracket was specifically designed to support the weight and size of the C1075s, and to prevent it from coming loose and dropping from the ceiling. Always use the PCB-C1000 Mounting Bracket when installing the C1075s speaker.
INTRODUCTION
Thank you for purchasing the C1075s Ceiling LCR Speaker. The directional woofer and pivoting midrange and tweeter make the C1075s a perfect choice for in-ceiling home cinema speaker setups, from stereo and LCR (left-center- right), to 3.1, 5.1 and 7.1 configurations. The three-way speaker system with 10″ woofer brings you an extraordinarily robust music or cinema experience, while the ±3dB midrange and tweeter adjustments provide ultimate fine-tuning to room size and acoustics, or according to personal preference.

SPEAKER PLACEMENT & SETUP
Before installing your C1075s Ceiling LCR Speaker, you should consider its
placement carefully, taking into account the location of HVAC ducts,
electrical conduit, plumbing lines, and other fixtures. For retrofit
installations, this can best be determined by noting the placement of fixtures
and gaining access to an attic or crawl space for further analysis of the
location of such obstacles.
Prior to the actual installation of the speaker, it will be necessary to run
wiring to the speaker location. After the wire has been properly installed,
you are ready to install the mounting bracket. For new construction, mount the
speaker after the drywall installation is complete.
Placement in Ceiling:
When placing your speaker into the ceiling, it should be located so that
the fixed 15˚ angle woofer is pointed toward the primary listening area. If
the speaker is positioned away from the primary listening area, simply adjust
the pivoting midrange and tweeter so they are pointed toward it.
Note: To avoid possible damage to the pivoting midrange and tweeter, read
the section entitled “SPEAKER ADJUSTMENTS” in this manual prior to performing
the adjustment. In very large rooms with low ceilings, it may be necessary to
place additional speakers throughout the room for better coverage.
MOUNTING BRACKET INSTALLATION – NEW CONSTRUCTION
(See Diagram 1)
The included PCB-C1000 Mounting Bracket is designed for both new construction
& retrofit installations. The PCB-C1000 Mounting Bracket may be installed
prior to drywall application across joists (from 16″ to 24″ on-center) where a
speaker will be located.
For new construction, always use the PCB-C1000 Mounting Bracket when
installing the C1075s speaker.
To install the mounting bracket in new construction:
Find the joists nearest the desired speaker mounting location.
- If you need to align the speaker to some other object or molding in the room, be sure to consider the size of the baffle flange which extends beyond the mounting hole.
- Line up bottom of one of the mounting bars with the bottom of the joist. This will place the screw holes in an “L” position, flush with the side of the joist, and the mounting ring “lip” will be facing downward. Attach the mounting bar to the joist using appropriate wood screws.
- Make sure that the mounting ring is in a perfectly circular shape by opening the bracket until the arms come in contact with the stoppers. Then, line up the bottom of the other mounting bar with the bottom of the same joist. Attach the mounting bar to the joist using appropriate wood screws.
- Stretch both mounting bars to reach the opposite joist, then line up the bottoms of each mounting bar with the bottom of the joist. Attach each mounting bar to the joist using appropriate wood screws.
- To adjust the position of the mounting ring between the joists, grab both sides of the mounting ring, where it connects to the mounting bar, then move the mounting ring into the desired position.
- The protruding lip of the mounting ring will force the drywall installers to hang the drywall with an appropriate hole cut out around the mounting ring lip. After the drywall has been hung and finished, the speakers are then easily installed following the instructions for mounting in “SPEAKER INSTALLATION” on the next page.
CAUTION: Speaker components can get hot while playing music at moderate to high volume levels. There should be nothing at all touching the speaker. Material in proximity to the back of the speaker must have at a minimum 1″ or 26 mm clearance for non-flammable materials and more for flammable materials like plastic vapor barriers.

MOUNTING BRACKET INSTALLATION – RETROFIT (See Diagrams 1, 2 & 3)
The included PCB-C1000 Mounting Bracket is designed for both new construction and retrofit installations. The intelligent folding design facilitates mounting the bracket through a speaker cut-out, therefore the mounting bracket may be installed across 16″ to 24″ on-center joists after drywall is installed. Always use the PCB-C1000 Mounting Bracket when installing the C1075s speaker.
Retrofit Installation – Finished Ceilings
Follow the first set of instructions to prepare the mounting surface for a professional-looking installation. Then, follow the second set of instructions for the mounting bracket installation.
To prepare the mounting surface in a retrofit installation:
- Find the joists nearest the desired speaker mounting location. We highly recommend using a good stud-finder tool for this procedure. If you need to align the speakers to some other object or molding in the room, be sure to consider the size of the baffle which extends beyond the mounting hole. Please allow 11/4″ space from the joist.
- Mark the hole. A template for setting the hole is provided in the box. Position the template in the desired position and pencil an outline on the ceiling.
- Cut the hole.
CAUTION: This is the most important part of the entire installation. If you are not certain whether any obstructions exist behind the desired mounting area, you should start by cutting a small hole in the center of your penciled mounting hole with a drywall saw, cutting at a 45°angle towards the inside of the hole. (See Diagram 3) Cutting the small hole at this angle will make drywall repair much easier, using the piece cut out. Once you have determined that there aren’t any obstructions in your desired mounting location, cut the finished hole at a 90° angle to the ceiling surface.
To install the mounting bracket in a retrofit:
-
Move the mounting bars in opposite directions, so that the mounting ring folds down to its narrowest width. Collapse the mounting bars to their shortest length.
-
With the mounting ring lip facing downward, insert
the mounting bracket into the ceiling cavity through the previously cut hole in the ceiling drywall. -
Make sure that the mounting ring is in a perfectly circular shape by opening the bracket until the arms come in contact with the stoppers, then set it into the ceiling hole. Push one of the mounting bar L-shaped edges until it is flush with the joist, and the bottom of the mounting bar lines up with the bottom of the joist. Attach the mounting bar to the joist using appropriate wood screws.
-
Push the other mounting bar L-shaped edge until it is flush with the same joist, and the bottom of the mounting bar lines up with the bottom of the joist. Attach the mounting bar to the joist using appropriate wood screws.
-
Stretch both mounting bars to reach the opposite joist, then line up the bottoms of each mounting bar with the bottom of the joist. Attach each mounting bar to the joist using appropriate wood screws.
CAUTION: Speaker components can get hot while playing music at moderate to high volume levels. There should be nothing at all touching the speaker. Material in proximity to the back of the speaker must have at a minimum 1″ or 26 mm clearance for non-flammable materials and more for flammable materials like plastic vapor barriers.
SPEAKER INSTALLATION
The unique integral mounting system incorporated into each Ceiling LCR Series speaker allows for a quick installation by following these easy steps:
-
Attach the speaker wire, observing the proper polarity with your amplifier, + to + and – to –. Make sure the appropriate channel of the amplifier is connected to the correct speaker (i.e. left, right or surrounds).
-
Be sure the mounting feet are turned inward to clear the opening, and insert the speaker into the ceiling. Position the speaker into the hole, being sure that the angled baffle is pointed toward the intended direction.
Tighten the screws on the front of the baffle only enough to make the speaker become snug against the ceiling. -
As you tighten the screws, the feet automatically flip into an outward position (See Diagram 4), and begin to tighten from the backside, thereby clamping the drywall between the feet and the speaker.
CAUTION: Overtightening may warp the baffle, crack the ceiling or cause difficulty in aligning the grille. -
Reattach the grille onto the speaker baffle.
SPEAKER ADJUSTMENTS
The Ceiling LCR Series speaker comes from the factory with the midrange and tweeter in line with the 15˚ angle of the woofer. This will result in the optimal directivity of the speaker system. However, depending on your particular primary listening area, room acoustics, ceiling height, or personal preference, you may find the sound more pleasing by pointing the midrange and/or tweeter in a particular direction.
For example, if additional treble is desired in the primary listening area, point the tweeter toward that area; and if less treble is required, point the tweeter away. Push gently at the edge of the tweeter to point it in the desired direction. For optimal directivity of the midrange, point it towards the listening area. If you wish to diffuse the midrange, such as when using a C1075s as a side-fill in a 7.1 setup, point the midrange speaker slightly away from the listening area.
CAUTION: Avoid touching metal dome tweeters or midrange speaker surfaces, as damage may occur. Carefully press on the edge of each pivoting mechanism as indicated. (See Diagram 5)
Tweeter Adjustment:
The switch labeled TREBLE allows for ±3dB of treble adjustment. Your speaker
shipped with the treble switch in the middle position, providing the most
linear frequency response. If you desire more treble, move the switch to the
“+” position, and the tweeter will play 3dB louder. If you desire less treble,
move the switch to the “–” position, and
the tweeter will play 3dB softer.
To return to the neutral setting, move the switch back to the middle position.
(See Diagram 6)
Midrange Adjustment:
The switch labeled MIDRANGE allows for ±3dB of midrange adjustment. Your
speaker shipped with the midrange switch set to the middle position, providing
the most linear frequency response. If you desire more midrange, move the
switch to the “+” position and the midrange will play 3dB louder. If you
desire less midrange, push the switch to the “–” position and the midrange
will play 3dB softer. To return to the neutral setting, move the switch back
to the middle position. (See Diagram 6)
PAINTING THE GRILLE
We recommend painting your grille prior to installation. If you decide to
paint it in the future, it’s best to remove the grille by simply detaching it
from the speaker. Do not paint the grille while it’s installed on the speaker.
Before painting, be sure to remove the cloth material from beneath the grille.
Once painted, place the cloth back to its position beneath the grille.
When painting, be careful not to clog the holes of the grille. The sound of
the speaker will be dramatically reduced if the perforations in the grille are
covered in paint.
Proficient recommends only light spray painting using five parts thinning
agent to one part paint.
