Unpacking Your Mythos XTR-50 Speakers
Please Inspect For Shipping Damage
Each loudspeaker leaves our plant in perfect condition. Any visible or concealed
damage most likely occurred in handling after it left our plant and should be reported
at once to your Definitive dealer or the delivery company that delivered your loud-
speaker. Please unpack your speaker carefully. Save all cartons and packing materials in
case you move or need to ship your speaker. Record the serial number found on the
back of the Mythos XTR-50 on this manual.
VERY IMPORTANT: Accessories
Various parts and accessories that you will need to use your Mythos XTR-50 are in
the carton but are easy to overlook. Open both ends of the shipping carton. Carefully
examine the contents of the shipping carton and packing material to find the plastic
bags with accessories.

OWNER’S MANUAL
Mythos XTR-50 Loudspeakers
Thank You
Thank you for choosing the Definitive Technology Mythos XTR-50 Loudspeaker
System. Our engineers spent many years developing this product. In order to ensure
that you experience the finest performance possible, we encourage you to take a
moment to fully read this owner’s manual and familiarize yourself with the proper
installation and set-up procedures for your Mythos XTR-50 speakers.
Definitive Technology
Connecting the Mythos XTR-50
The wire connection method used on the Mythos XTR-50 is
different than most speakers so please read these instructions!
(NOTE: if you are using the table stands, you should pass the wire through
the wire channels before attaching the green speaker wire connector.)
1. In the accessories plastic bag you will find a small green plastic
connector as shown in Figure 1.
2. Strip 1⁄2 inch (12 mm) of insulation from each conductor of the
speaker wire to expose the bare metal and twist each of the
individual conductors into single un-frayed strands.
3. Use a small jewelers screwdriver to loosen the screws on the
connector just enough to allow the wire ends to fit in
the holes. [Figure 1]
4. Slip the wire ends into the holes and tighten the screws until the
wire is firmly attached to the connector. (NOTE: if you are using
the table stands, you should pass the wire through the wire
channels before attaching the wire connector.)
Note that one of the terminals is marked
with “+” and the other is marked with “-“.
Make certain that you connect the wire
from the red (+) terminal of your amplifier
or receiver to the “+” terminal on your
speaker and the wire from the black (-)
terminal of your amplifier or r
eceiver to the
“-“ terminal on your speaker. Most speaker
wire has some indicator (such as color-
coding, ribbing or writing) on one of the
two conductors to help you maintain
consistency. It is essential to connect both
speakers to the amplifier in the same way
(in phase). If you experience a lack of bass
or poor surround effect, it is likely that one
or more of the channels is connected in
incorrect polarity and needs to be rewired.
Pay closer attention to connect
positive to positive and negative to
negative on all channels.
5. Gently push the male
connector with the wire into
the female receptacle on the
speaker. The connector is
designed so that it can
only go in one way with the
correct orientation of positive
and negative pins. [Figure 2]
6. Connect a single RCA cable from the “SUB OUT” of your receiver
to the LFE input of the subwoofer (not included). [Figure 3] This
connecting method bypasses the subwoofer’s internal “crossover”
or low pass filter and relies on the crossover filter built into
your receiver.
7. See page 4 for instructions on Speaker Set Up in your
surround receiver.

Wall Mounting the Mythos XTR-50
• We recommend that wall-mounting of speakers be performed by
professional installers or by those skilled in the use of power tools
and the knowledge of building codes and structural issues.
• We recommend that you determine a suitable location for your
speaker installation, and that you complete all wiring (especially
“hidden” in-wall wiring) before mounting the brackets to your walls.
• Mythos wall-mount brackets are not suitable for ceiling mounting.
The Mythos XTR-50 loudspeaker comes with a wall-mounting
bracket that can make mounting easier but in most cases the
bracket is not necessary to wall-mount the speaker. The supplied
bracket may be necessary when mounting the speaker to a full-
motion or tilting TV wall-mount. You may choose to use the
supplied wall-mount bracket if you want the speaker to protrude a
bit more from the wall (total depth without the bracket is 1.5 inches
[38mm] and 1.6 inches [40mm] with the bracket). The bracket is
padded with foam that may be useful for damping rattles or
vibrations between speaker and wall surface.
Follow these directions for wall mounting the speaker without
using the bracket.
1. Two cardboard mounting templates are supplied, one for
horizontal speaker orientation and the other for vertical. Be sure
to use the correct template. Hold the cardboard template in the
intended location. Make sure the speaker clears the ceiling,
adjacent walls, corners, beams, lighting fixtures and door/window
frames. Leave at least 1" (25 mm) above or to the side of the speaker
location to allow the speaker to slide onto the screws.
2. Make sure the center of the template is centered with the TV
screen’s center points.
3. When mounting the speaker horizontally, use a bubble level to
make sure the template is level.
4.
When mounting the speaker vertically, use a plumb line to find
perfect vertical. If the TV is off-level or off-plumb, the speaker will
look better if it is off-level or plumb in exactly the same way as the TV.
5. Use push pins to secure the template to the wall.
6. Make pencil marks in the holes labeled “Pilot Hole (for mounting
without bracket)”; remove the template.
If you intend to place the Mythos XTR-50 on a TV or shelf
in a horizontal orientation, see page 3.

7. Pre-drill the pilot-hole locations for mounting screws (not included).
Use screws rated to hold securely in the wall material and have
screw heads (flat or panhead are acceptable) at least 0.33 inch
(8.5mm) in diameter.
8. It is best if at least one screw hits a wall stud.
If there is no stud behind the pilot-hole
location, install wall anchors (not included)
to secure the bracket screws. [Figure 5] Follow
the wall anchor manufacturer’s directions.
Each wall anchor should be rated to hold at
least one half of the product net weight
[see specifications on page 1].
9. For masonry walls, use a masonry drill bit to
pre-drill holes, and use masonry anchors and
screws (not included).
10. Drive in the screws until the head is approxi-
mately 0.12 inch (3mm) away from the wall.
If the screws are driven too close to the wall,
you will not be able to slip the speaker onto
the screw heads. If the screws are not close
enough to the wall, the speaker will be loose
and may rattle when played.
11. Push the speaker connector into the female receptacle on the back
of the speaker (see page 2).
12. Line up the speaker so that the screws enter the center part of the
+ shaped channels; slide the speaker down so that the screw heads
hold the speaker in place. [Figure 4]
13. Gently pull on the speaker to make sure the screws are firmly
holding the speaker.
14. If the speaker is not held tightly to the wall, drive the screws in a
little deeper and try again.
Follow these directions for installing the speaker with the wall-
mounting bracket.
1. The supplied cardboard mounting template is double-sided; one
side is for horizontal orientation and the other is for vertical
mounting. Be sure to face the correct side toward you. Hold the
cardboard template in the intended location. Make sure
the speaker clears the ceiling, adjacent walls, corners, beams,
lighting fixtures and door/window frames. Leave at least 1" (25 mm)
above or to the side of the speaker location to allow the speaker to
slide onto the screws.
2. Make sure the center of the
template is centered with the TV
screen’s center points.
3. When mounting the speaker
horizontally, use a bubble level to
make sure the template is level.
4.
When mounting the speaker vertically, use a plumb line to find
perfect vertical. If the TV is off-level or off-plumb, the speaker will
look better if it is off-level or plumb in exactly the same way as the TV.
5. Use push pins to secure the template to the wall.
6. Make pencil marks in the holes labeled “Pilot Hole”;
remove the template.
7. Pre-drill the pilot-hole locations for mounting screws (not included).
Use flat head screws rated to hold securely in the wall material and
have screws heads between 0.25 inch (6.4mm) and 0.33 inch
(8.4mm) in diameter.
8. It is best if at least one screw hits a wall stud. If
there is no stud behind the pilot-hole location,
install wall anchors (not included) to secure the
bracket screws. [Figure 5] Follow the wall anchor
manufacturer’s directions. Each wall anchor should
be rated to hold at least one half of the product net
weight [see specifications on page 1].
9. For masonry walls, use a masonry drill bit to
pre-drill holes, and use masonry anchors and
screws (not included).
10. Secure the bracket to the wall with screws driven
into the pilot holes or wall anchors. Bracket should
be tight to the wall, and screw heads should be
flush with the bracket.
11. Attach the supplied male connector to the speaker
wire and plug the connector into the receptacle on
the speaker (see page 2).
12. Line up the speaker so that the mounting heads enter the center
part of the + shaped channels; slide the speaker down so that the
mounting heads hold the speaker in place. [Figure 6]
13. Gently pull on the speaker to make sure the screws are firmly
holding the speaker.
Mounting the Mythos XTR-50 to an
articulating TV bracket
If you have a Plasma or LCD TV that is attached to the wall via a
swing-out articulating bracket such as those offered by Chief and
Sanus, consult the TV bracket manufacturer’s user manual for
specific speaker mounting instructions.
Shelf/Table Mounting
If you are going to use the Mythos XTR-50 in horizontal mode on a
shelf or table, first attach the two supplied
rubber pads to the bottom edge of the speaker.
[Figure 7] Assemble the L-brackets to the
threaded holes in the back of the speaker using
the 1/4 20 x 12mm long screws provided.
[Figure 8] Thread the foot screws into “L”
brackets and adjust to tilt the speaker up or down to aim
the speaker toward seated listener ear height.
If you are going to vertically mount the speaker on
a shelf or table, do not attach the wall mount
bracket to the speaker. Follow these steps:
1. Assemble the shelf stand using [Figure 9] as a guide.
2. Pass the speaker wire through the wire channel
and attach the male speaker connector to the
speaker wire as shown on Page 2.
3. Assemble the provided screw and square-neck nut onto the lower
hole in the back of stand leaving a 3mm gap between the nut
flange and the stand. [Figure 10]
4. Line up the center of the + shaped channel with the square-neck
nut on the stand and push the speaker in and down on the nut.
5. Thread the provided 1/4 20 screw through the top hole in the
stand into the threaded hole in the speaker and tighten the screw.
