Cutting the hole.
CAUTION:This is the most important part of the entire
installation.
If you are uncertain 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 45º angle
towards the inside of the hole.
(See Diagram 2)
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 90º angle to the ceiling surface.
5.
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
Your CRS 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 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 tweeter dome as
damage WILL occur on metal dome tweeters (CRS THREE & FOUR).
Tweeter Adjustment (CRS TWO, THREE & FOUR):
The switch labeled TREBLE allows for 6dB of tweeter adjustment. Your speakers were shipped with the
treble switch in the neutral position, providing the most linear frequency response. If you desire more
treble, roll the switch to the “+” position, and the tweeter will play 3dB higher. If you want less treble,
roll the switch to the “-” position and the tweeter will play 3dB lower. To return to the
neutral setting, slide the switch to the middle position.
(See Diagram 4)
Woofer Adjustment (CRS THREE & FOUR):
The switch labeled BASS allows for 6dB of bass adjustment. Your speakers were shipped with the bass
set to neutral, resulting in 6
Ω
of impedance. This setting provides the flattest bass frequency response. If
you desire more bass, roll the switch towards “+” and the bass will play 3dB higher and lower the
impedance to 4
Ω
. If you want less bass, roll the switch towards “-” and the bass will play 3dB lower and
increase the impedance to 8
Ω
. This setting provides a more linear bass frequency response. To return to
the neutral setting, slide the switch to the middle position.
(See Diagram 5)
Remember that altering the
impedance affects the number of speakers able to be driven by an amplifier. If multiple pairs of speakers
are to be driven by one amplifier, SpeakerCraft suggests using the lowest output position (switch rolled
towards the “-” position) until it is determined that the amplifier will operate properly with the speakers
switched to a higher output mode. If you want to safely operate multiple pairs of speakers, consider
purchasing SpeakerCraft S4 or S8 Speaker Selectors.
SPEAKER INSTALLATION
The unique integral four foot mounting system incorporated into each CRS 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.
