Frequently Asked Questions - Ceiling C500 Proficient

How do I install the Ceiling C500?

Use a template to cut a hole in the ceiling. Run speaker wire from your amplifier, connect to the spring terminals, and secure the speaker with the included mounting clamps. Ensure the ceiling material is at least 1/2 inch thick.

Can I paint the grille to match my ceiling?

Yes, the steel grille is paintable. Remove the grille, clean it, and apply a thin coat of spray paint designed for metal. Let it dry completely before reinstalling.

What impedance does the speaker have?

The Ceiling C500 has an impedance of 8 ohms, which is standard for most home audio receivers.

What is the maximum power this speaker can handle?

It can handle 60 watts RMS and up to 120 watts peak. Pair it with an amplifier delivering 20 to 80 watts per channel for best performance.

Is the speaker suitable for bathrooms or humid areas?

No, the Ceiling C500 is not rated for moisture or outdoor use. It is designed for indoor, climate-controlled environments.

What size hole do I need to cut for installation?

The required cutout diameter is 7.7 inches (195 mm). Use a template provided in the manual or a circle cutter.

Does it come with a grille?

Yes, the speaker includes a white, paintable steel grille that attaches magnetically.

Can I use this speaker for a surround sound system?

Absolutely. It works well as a surround channel or ceiling-mounted height speaker in a home theater setup.

How do I clean the speaker?

Use a dry, soft cloth to dust the grille. Avoid using water or cleaning solvents. For deeper cleaning, remove the grille and vacuum gently.

What is the warranty period?

The Proficient Ceiling C500 comes with a 5-year limited warranty against defects in materials and workmanship.

USER MANUAL Ceiling C500 Proficient

Before installing your speakers, you should consider their placement carefully, taking into account the location of electrical, plumbing and other fixtures. Contact your Dealer for assistance if you are unsure of the best location for your particular listening environment.

Placement In Ceiling: When placing your speakers into the ceiling, they should ideally be located above the primary listening area. If the speakers are positioned far away from the primary listening area, adjust the pivoting tweeters so they are pointed towards it.

Note: To avoid possible damage to the pivoting tweeters, read the section entitled “SPEAKER ADJUSTMENTS” in this manual prior to performing the tweeter adjustment.

In a very large room with high ceilings, it may be necessary to place additional speakers throughout the room. Contact your Proficient Audio Systems Dealer for assistance.

MOUNTING SURFACE PREPARATION

New Construction - Unfinished Ceilings

A Pre-Construction Bracket, available from your Dealer, may be installed prior to drywall application across joists (up to 24" on-center) where a speaker will be located. After the hole is cut and the drywall is installed, the speakers are then easily installed following the instructions for mounting in "Finished Ceilings" below. Note: If the speakers are to be mounted more than 24" on-center, a special "Extra Long Wing" is available from your Dealer.

Finished Ceilings

Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker locations. See your Dealer for more information about cable installation. After the cable has been properly installed, you are ready to mount the speakers. Following the simple steps listed below will result in a professional looking installation:

1. Determine the best area to mount your speakers. This area of the ceiling should be free of obstructions such as electrical conduit, HVAC ducts, or water lines. 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.

2. Find the joists nearest the desired speaker mounting location. We highly recommend using a good stud-finder tool for this procedure. If you are lining up the speakers to some other object or molding in the room, make sure you consider the size of the baffle flange which extends beyond the mounting hole.

3. Mark the hole. A template for setting the hole is provided in the box (along with two paint mask inserts for use when painting). Position the template in the desired position and pencil an outline on the ceiling.

4. Cutting 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 1) 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, start cutting the finished hole at a 90^ angle to the ceiling surface.

1. Add insulation. If the area in the ceiling is not already insulated, add an adequate amount insulation material to loosely cover the back of the speaker. If the insulation material used is faced with foil or paper, position the foil or paper away from the speaker.

SPEAKER ADJUSTMENTS

The Ceiling Series speakers come from the factory with the tweeter facing straight out from the baffle. This will result in the overall smoothest response. 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 tweeters in a particular direction. If additional treble is desired in the primary listening area, point the tweeter towards 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. (See Diagram 2) CAUTION: Avoid touching metal dome tweeters, as damage may occur (C640 and C800).

Diagram 2: Tweeter

Push Tweeter Here

The switch labeled TREBLE allows for 3dB of treble adjustment. Your speakers were shipped with the treble switch in the “-” position, providing the most linear frequency response. If you desire more treble, move the switch to the “+” position, and the tweeter will play 3dB higher. To return to the neutral setting, push the switch back to the “-” position. (See Diagram 3)

Woofer Adjustment (C640 & C800):

The switch labeled BASS allows for 3dB of bass adjustment. Your speakers were shipped with the bass set to “-”. This setting provides the flattest bass frequency response. If you desire more bass, push the switch to the “+” position and the bass will play 3dB higher. To return to the neutral setting, push the switch back to the “-” position. (See Diagram 3)

SPEAKER INSTALLATION

The unique integral four-foot mounting system incorporated into each Ceiling Series speaker allows for a quick installation by following these easy steps:

1. Remove the grille. It may be necessary to push one or two of the mounting screws and its attached foot towards the baffle and against the inside surface of the grille to force the grille out of its retaining groove.
2. Attach the speaker cable (observing the proper polarity with your amplifier, + to + and - to -). Make sure the left channel of the amplifier is connected to the left speaker, and the right channel is connected to the right speaker.
3. Make sure the mounting feet are turned inward to clear the opening, and insert the speaker into the ceiling. Position the speaker into the hole.

Note: The flange of the speaker is designed to flex and conform to any small imperfections in the ceiling's surface. Tighten the four screws on the front of the baffle only enough to make the flange become snug against the ceiling. As you tighten the screws, the feet will automatically flip into an outward position (See Diagram 4), thereby clamping the drywall between the feet and the flange. CAUTION: Over-tightening may warp the baffle, crack the ceiling, cause the flange to distort, and make the grille difficult to install.

1. Push the grille firmly into the slot in the speaker baffle.
   

PAINTING THE SPEAKERS

If you plan to paint your speakers, we recommend that it be done prior to installation. If you plan to paint your speakers sometime in the future, it is best to remove them by simply reversing the steps for “SPEAKER INSTALLATION” above.

If it is necessary to paint the speakers when they are in the ceiling, the paint masks provided in the carton must be installed between the grille and flange while they are being painted with the ceiling.

Before painting your speakers, remove the material under the grilles. Once the speakers have been painted, return the material back into place.

Great care should be taken not to clog the holes of the grille, as this will reduce the sound quality of the speakers.

Proficient Audio Systems recommends only light spray painting using 5 parts thinning agent to 1 part paint.
