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 par- ticular 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).

The switch labeled TREBLE allows for 3dB of treble adjust- ment. 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 sur- face. 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.

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.
