The Ceiling LCR 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 3) CAUTION:
Avoid touching metal dome tweeters, as damage may occur
(C871 & C661).
The unique integral four-foot mounting system incorporated
into each Ceiling LCR Speaker allows for a quick installation by
following these easy steps:
1. Remove the grille from the speaker baffle.
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, the right
channel is connected to the right speaker, etc.
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 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 speaker become snug against the
ceiling. As you tighten the screws, the feet will automatically
flip into an outward position (See Diagram 2), thereby clamp-
ing the drywall between the feet and the speaker.
CAUTION: Over-tightening may warp the baffle, crack the
ceiling or cause difficulty in aligning the grille.
4. Reattach the grille onto the speaker baffle.

Tweeter Adjustment (C871 & C841 Only):
The switch labeled TREBLE allows for ±3dB of treble adjust-
ment. Your speakers were 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 higher. If you desire less treble,
move the switch to the “–” position, and the tweeter will play
3dB lower. To return to the neutral setting, push the switch
back to the middle position. (See Diagram 4)
Woofer Adjustment (C871 & C841 Only):
The switch labeled BASS allows for ±3dB of bass adjustment.
Your speakers were shipped with the bass set to the middle
position. 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. If you desire less
bass, push the switch to the “–” position and the bass will play
3dB lower. This setting provides a more linear bass frequency
response. To return to the neutral setting, push the switch back
to the middle position. (See Diagram 4)
