Mirror Image Technology In-Wall Loudspeakers
Congratulations on your purchase of SpeakerCraft “Mirror Image Technology” In-Wall Speakers. Your
speakers are equipped with pivoting dome tweeters, which allow you to direct the sound toward or
away from a listening area, and “Mirror Image Technology” in which the tweeters are mounted in an
asymmetrical offset position to their baffles. This design minimizes diffraction and reflection effects for
better stereo imaging than speakers with conventional center positioned tweeters. SpeakerCraft has a
wide variety of accessories to compliment your Mirror Image Technology In-Wall Speakers. Contact your
dealer or SpeakerCraft direct for more details.
SPEAKER PLACEMENT
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.
SpeakerCraft offers a variety of accessories to make your installation of these speakers and other SpeakerCraft products easy,
economical, and professional. Contact your authorized SpeakerCraft Dealer for more information.

Placement In Wall: When installing your speakers into the wall, ideal
sound will be achieved when the tweeters are placed at ear level or slightly
higher and the usual listening area is no closer to the wall than the distance between the speakers themselves. (See Diagram 1) The MT6 series is
designed with the tweeter below the woofer to facilitate optimum imaging.
If the speakers are positioned far away from the primary listening area, adjust
the pivoting tweeters so they are pointed toward the primary listening area.
Note: To avoid possible damage to the pivoting tweeters, read the section entitled
“SPEAKER ADJUSTMENTS” in this manual prior to performing the tweeter adjustment.

Ideal Placement
MOUNTING SURFACE PREPARATION
New Construction - Unfinished Walls
A New Construction Bracket, SpeakerCraft P/N BKT90601 (available from your dealer), may be installed prior to drywall
application across studs (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 Walls”. Note: If the speakers are to be mounted more than 24" on-center,
a special “Extra Long Wing”, SpeakerCraft P/N WING90226, is available from your dealer.
Finished Walls
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 wall 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 studs 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 on all four sides.
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 wall.

Wall Cut Out
5. Add insulation. If the area in the wall is not already insulated, add an adequate amount of
insulation material to fill the wall cavity. If the insulation material used is faced with foil or
paper, position the foil or paper away from the speaker.

Woofer Adjustment (MT6 THREE & FOUR):
The 3 vertical buttons with the center button labeled “B” allow 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 desire more bass, push the button with the up arrow
and the bass will play 3dB higher and lower the impedance to 4ohm. If you want less bass, push the
button with the down arrow 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, push the
“B“ button. (See Diagram 4) 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 (the down arrow) 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.
6. Adjust the BASS (MT6 THREE & FOUR) and TREBLE (MT6 TWO, THREE & FOUR) switches to the
desired position.

7. Push the grille firmly into the slot in the speaker baffle.
PAINTING THE SPEAKERS
Diagram 3:
Tweeter
If you plan to paint your speakers, we recommend that it be done prior to installation. If you decide to paint your speakers sometime in
the future, it is best to remove them by simply reversing the steps for Speaker Installation listed above. When painting the speakers, the
paint masks provided in the carton must be installed in place of the grille. 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 material under grille, follow the same procedure used to paint the grilles.
SPECIAL FIRE WALL INSTALLATION
If you plan to mount your speakers in a fire-rated wall, you should purchase SpeakerCraft 6” Rectangle Sound Enclosures, model #SE1612.
This metal enclosure mounts easily between studs, and contains a standard electrical connector for connecting your speaker cable directly
to the speaker.
LIMITED LIFETIME WARRANTY
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.

Note: Your MT6 Series speakers may have come with the optional Jawz speaker wire connector. Before using Jawz , please follow the
instructions included with the connector.

4. Position the speaker into the hole and start tightening the six screws evenly. This will cause the
mounting bars to properly sandwich the drywall between the self-adjusting mounting bar feet and
the speaker flange. Make sure the speaker is positioned correctly before final tightening of the six
mounting screws. Note: The flange of the speaker is designed to flex and conform to any small
imperfections in the wall’s surface. The tension on the screws should not be tightened so that the
flange bows out. If this occurs, back off the tension on the screws until the bowing is eliminated.
5. Adjust the pivoting tweeter to the desired position.
SPEAKER ADJUSTMENTS
Tweeter Adjustment (MT6 TWO, THREE & FOUR):
The 3 vertical buttons with the center button labeled “T” allow for 6dB of TREBLE adjustment. Your
speakers were shipped with the treble set to neutral. This setting provides the most linear frequency
response. If you desire more treble, push the button with the up arrow and the treble will play 3dB
higher. If you want less treble, push the button with the down arrow and the tweeter will play 3dB
lower. To return to the neutral setting, push the “T” button. (See Diagram 4)
Page 3
3. Slide the ends of the two mounting bars at the tweeter end of the speaker behind the drywall so
the drywall is now between the mounting bars and the back of the speaker baffle. This should be
enough room for the other ends of the mounting bars to clear the other end of the drywall hole
and slide behind the drywall as well. (See Diagram 5)
4. Cutting the hole. CAUTION: This is the most important part of the entire installation.
If you are not certain 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. Cut 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 as the piece cut
out can be installed neatly back into the hole. Once you have determined there aren’t
any obstructions in your desired mounting location, start cutting the finished hole at a
90º angle to the wall surface.
The Mirror Image Technology 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.
When used in a home theater surround sound environment as side or rear channel speakers, the best
result will be obtained by pointing the tweeters toward an adjacent wall. 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
(MT6 THREE & FOUR).

The unique integral mounting bar system incorporated into your MT6 Series speaker allows for a quick installation by following the easy
steps below:
1. Remove the grille by pushing the two mounting bars, located at the rear of the speaker, towards the front of the speaker. The long
screws attached to the mounting bars will force the grille off the 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, and the right channel is connected to the right speaker.
