Caution: The XRT2K when assembled weight is 452 pounds
(205.0kg). It requires four or more persons to safely
handle the Loudspeaker System.
1. Loudspeaker Cables of adequate size are important to ensure
that there will be no significant power loss or heating. Cable
size is specified in Gauge numbers or AWG (American Wire
Gauge). The smaller the Gauge number, the larger the wire
size:

If the Loudspeaker Cables are 100 feet (76.2m) or less, use
at least 10 Gauge (AWG) wire size or larger.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the XRT2K
Loudspeaker.
3. The XRT2K’s built-in speaker protection incorporates five
automatic resetting solid-state devices in the crossover
networks. One protects the tweeters, one for the midranges
and three for the woofers. The protection allows a certain
amount of overdrive but extended periods will trigger
protection. If an obvious lack of high, mid or low frequencies
is noticed, the Protection Device may have activated. These
devices will automatically reset when the volume level is
reduced significantly and kept low until the output of the
affected Loudspeaker Element returns to normal.
4. When the XRT2K Loudspeaker System is driven by more than
one amplifier, the output levels of the different amplifiers
connected to the Loudspeaker System must be adjusted to
achieve a proper balance between the low, midrange and
high frequencies reproduced. This adjustment is best
achieved through the use of audio test equipment operated
by a qualified installer.

Introduction
For the first time, the new McIntosh XRT2K Loudspeaker
System is capable of reproducing the full dynamic range of
a symphony orchestra including pipe organ without audible
distortion. McIntoshAcoustic Engineers have refined the

woofer design also utilizes an aluminum shorting ring, cop-
per capped pole piece, three inch diameter voice coil and
two cone centering devices. This results in lower distortion
due to more linear magnetic flux in the voice coil gap. A
good example of this low distortion is incredible smoothness
and effortless clarity in the reproduction of the human voice.

The Loudspeaker Elements and Crossover Components of
the XRT2K are all chosen for use with powerful amplifiers
up to 2,000 watts.
Superior Imaging
•
Locating the Column of Tweeters between the two Columns
of Midranges generates a symmetrical horizontal polar
response for superior imaging.
Versatile Operation and Placement
•
Figure 7
In additional to the regular connections, the XRT2K Loud-
speaker System provides separate connections for Bi-Am-
plification and Tri-Amplification hookups, as well as Bi-
Wiring and Tri-Wiring.
Order designs keep the speakers operating within their opti-
mum frequency range while offering the best blending of
each speaker. All network inductors are air core designs; so
they will not add distortion. All network capacitors are film
type for extra reliability. All the Capacitors and Inductors
are chosen for high current capacity. Each section of the
network utilizes it own self resetting high current PTC type
fuses to provide an extra measure of protection.
• Extruded and Machined Side Panels and Column
The sides of the XRT2K Low Frequency enclosures and the
Midrange/Tweeter Column enclosure are machined from
extruded thick aluminum panels to be non-parallel and are
given a High Gloss Black Piano Type Finish.

Room Placement
Room Placement
Loudspeaker placement in a room can greatly affect
performance. The XRT2K Loudspeaker is designed for both
Music and Home Theater Systems. The optimal method for
selecting speaker locations includes the use of a real time
spectrum analyzer operated by an experienced system
installer.An uncompromising installation would take into
consideration the floor, wall and ceiling coverings, the type
and placement of furniture and can even include the
architectural design of the room and its construction
materials. In those instances where placement in the room is
fixed an environmental equalizer may be needed to restore
proper musical balance.
Placement near a wall, corner, floor, ceiling or any inter-
secting surfaces will reinforce some bass frequencies.
Which bass frequencies are boosted by placement in a par-
ticular location is dependent on the dimensions of the room.
Test the various Loudspeaker locations by playing music
with continuous bass, setting up the speakers and listening
to them from the main listening spot. Move the Loudspeak-
ers to an alternate location and repeat the listening, paying
attention to how the bass qualities and response levels
change. Do not assume the loudest bass is best; rather listen
for booming (a lack of articulation), as well as a balance
over the whole spectrum, to assure the bass will not drown
out the other parts of the music. Experiment with various
Loudspeaker positions until the locations that sound best are
found.
Figure 9
The XRT2K Midrange/High Frequency Column’s
Smooth Frequency Response may be altered by large ob-
ject(s) located in the sound waves path or by locating the
column too close to a side wall. There should be an unob-
structed area in front of the column of at least 60 degrees
either side from the center axis for the best performance.
Refer to figure 9.
Figure 10
Locating Loudspeakers for use in Home Theater
In a Home Theater application, the placement of Left and
Right Front Loudspeakers can be limited by such
considerations as the size and location of the video monitor.
The locating suggestions in the “for use in a Music System”
section below can still be helpful as a starting place. Refer
to figure 10.
Locating Loudspeakers for use in a Music System
When used in a Music System the distance between the
Loudspeakers and the listener to the Loudspeakers should
form a equilateral to an acute isosceles triangle. If the
speakers are too far apart relative to the listener, some
imaging can be lost. Refer to figure 11.

1. Prepare two 14 inch (35.6cm) Jumper Wires for
connecting the Low Frequency Column, Lower
and Upper Sections together by choosing one of
the methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from
the cable ends, refer to figures 12, 13 & 14.
If the cable
is stranded,
carefully
twist the
strands to-
gether as tightly as possible.
Note: If desired, the twisted ends can be
tinned with solder to keep the strands
together or attach spade lugs.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared
section of the cable end into the terminal
side access hole, and tighten the terminal
cap until the cable is firmly clamped into
the terminal so the wires cannot slip out.
Refer to figures 15, 16 & 17.
