Loudspeaker Performance
The Sound Waves from the XRT2.1K Column Loud-
speaker produces a very high performance Cylindri-
cal Wave Front. This produces a stable symmetrical
horizontal sound dispersion image, while minimizing
undesirable floor and ceiling reflections that detract
from a stable sound image. Referring to the illustra-
tion in figure 18, the Loudspeaker on the left side
produces a Cylindrical Wave Front while the Loud-
speaker on the right side produces a conventional
Spherical Wave Front.

Loudspeaker Placement
Loudspeaker placement in a room can greatly affect
performance. The XRT2.1K Loudspeaker is designed
for both Music and Home Theater Systems. The op-
timal 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
intersecting surfaces will reinforce or diminish some
bass frequencies. The bass frequencies that are altered
by placement in a particular location are dependent on
the dimensions of the room. If professional measure-
ment equipment is not available, listen to the Loud-
speaker. Try various locations by listening to music
containing continuous bass and finding a location
where there is an overall musical balance in the sound
and the bass content does not dominate.
The XRT2.1K's Smooth Frequency Response may
be altered by a large object(s) located in the sound
waves path or by locating the Loudspeaker too close
to a side wall. There should be an unobstructed area in
front of the Loudspeaker of at least 30 degrees either
side from the center axis for the best performance.
Refer to figure 19.

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 can still be helpful as a starting
place. Refer to figure 20.
Figure 20
Locating Loudspeakers for use in a Music System
When used in a Music System, the distance between
the Loudspeakers and the listener to the Loudspeak-
ers should form an equilaterial or an acute isosceles
triangle. If the speakers are too far apart relative to the
listener, some imaging can be lost. Refer to figure 21.
