Custom Round Series In-Ceiling Loudspeakers
Congratulations on your purchase of SpeakerCraft CRS6 Series In-Ceiling Speakers. All CRS6 Series speakers
are equipped with pivoting dome tweeters, which allow you to direct the sound toward, or away from, a
listening area to achieve a desired effect. In addition, each CRS6 model comes equipped with WavePlane ,
SpeakerCraft’s revolutionary tweeter baffle. SpeakerCraft has a wide variety of accessories to compliment
your CRS6 Series speakers. Contact your dealer or SpeakerCraft direct for more details.
Before installing your speakers, you should consider the placement
carefully, taking into account the location of electrical, plumbing
and other fixtures. Contact your dealer for assistance if you are not
sure of the best location in your particular room environment.
Placement In Ceiling: When placing your speakers in the ceiling,
they should ideally be located above the primary listening area.

In a very large room with low ceilings, it may be necessary to place additional speakers throughout the room.
Contact your Authorized SpeakerCraft dealer for assistance.
New Construction - Unfinished Ceilings
A New Construction Bracket, SpeakerCraft P/N BKT90611 (available from your dealer), may be installed prior to drywall
application across joists (up to 24" on-center) where a speaker will be located. Insulation material should be in place prior
to installing drywall. After the hole is cut and the drywall is installed, the speakers are then easily installed following the
instructions for mounting in “Finished Ceilings”. Note: If the speakers are to be mounted more than 24" on-center, a
special “Extra Long Wing”, SpeakerCraft P/N WING90222, 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 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.
impedance to 4ohm. If you want less bass, roll the switch towards “–” and the bass will play 3dB lower
and increase the impedance to 8ohm. This setting provides a more linear bass frequency response. To
return to the neutral setting, slide the switch to the middle position. (See Diagram 6) 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.
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.

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” on page 2. If it is necessary to paint the speakers while they are still in the ceiling, the paint masks provided in
the carton must be installed in place of the grille while the flange is being painted with the ceiling. The grilles can also be painted, however, great care should be taken not to clog the holes, as this will greatly reduce the sound quality of the speakers. SpeakerCraft recommends only light spray painting using 5 parts thinning agent to 1 part paint. Do not paint the grilles while they are attached to the speaker.
If it is necessary to paint the under grille material, follow the same procedure used to paint the grilles.
Push Tweeter
The unique integral four foot mounting system incorporated into each CRS6
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 flange to distort, and make the
grille difficult to install.
If you plan to mount your speakers in a fire-rated ceiling, you should purchase SpeakerCraft 6" Round Sound Enclosures, model #SE1612.
The metal enclosures mount easily between joists, and contain a standard electrical type connector for connections of your speaker cable
directly to the speaker.

SpeakerCraft Inc. warrants to the original retail purchaser only that this SpeakerCraft product will be free from defects in materials and workmanship,
provided the speaker was purchased from a SpeakerCraft Authorized Dealer.
Defective products must be shipped, together with proof of purchase, prepaid insured to the SpeakerCraft Authorized Dealer from whom they were purchased, or to the SpeakerCraft factory at the address listed on this installation instruction manual. Freight collect shipments will be refused. It is preferable
to ship this product in the original shipping container to lessen the chance of transit damage. In any case, the risk or loss or damage in transit is to be

workmanship at any time during this warranty period, SpeakerCraft or the SpeakerCraft Authorized Dealer will, at its option, repair or replace this product
at no additional charge, except as set forth below. If this model is no longer available and can not be repaired effectively, SpeakerCraft, at its sole option
may replace the unit with a current model of equal or greater value. In some cases where a new model is substituted, a modification to the mounting
surface may be required. If mounting surface modification is required, SpeakerCraft assumes no responsibility or liability for such modification. All replaced
parts and product become the property of SpeakerCraft Inc. Products replaced or repaired under this warranty will be returned to the original retail
purchaser, within a reasonable time, freight prepaid.
4. Push the grille firmly into the slot in the speaker baffle.
Your CRS6 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 (CRS6 THREE & FOUR).

Tweeter Adjustment (CRS6 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 5)
All implied warranties on the product are limited to the duration of this expressed Warranty. Some states do not allow limitation on the length of an implied
warranty. If the original retail purchaser resides in such a state, this limitation does not apply.
Woofer Adjustment (CRS6 THREE & FOUR):
The switch labeled BASS allows for 6dB of bass adjustment. Your speakers were shipped with the bass set
to neutral, resulting in 6ohm of impedance. This setting provides the flattest bass frequency response.
If you
