4. 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.

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 CRS8 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 prefer-
ence, you may find the sound more pleasing by pointing the tweeters in a particu-
lar 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.

Treble Adjustment (CRS8 Two, Three & Four):
The switch labeled TREBLE allows for 6dB of treble (high frequency) 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.

Bass Adjustment (CRS8 Three & Four):
The switch labeled BASS allows for 6dB of bass (low frequency) adjustment. Your speakers were shipped
with the bass set to neutral, resulting in 6Ω 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 4Ω. If you want less bass, roll the switch towards “-” and the bass will play 3dB lower and
increase the impedance to 8Ω. 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 imped-
ance 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 high- er
output mode. If you want to safely operate multiple pairs of speakers, consider purchasing SpeakerCraft S4 or S8
Speaker Selectors.

SPEAKER INSTALLATION
Note: Your CRS8 Series speakers may have come with the optional Jawz
™
speaker wire connector. Before
using Jawz
™
, please follow the instructions included with the connector.
The unique integral four foot mounting system incorporated into each CRS8 speaker allows for a quick
installation by following these easy steps:
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 speak- er
