Loudspeaker placement in a room can greatly affect
performance. The XR27 Loudspeaker System 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 in-
tersecting 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
Loudspeakers to an alternate location and repeat the listen-
ing, paying attention to how the bass qualities and re-
sponse 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. Ex-
periment with various Loudspeaker positions to determine
the best sounding location.
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 18.

Room Placement
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 an isosceles triangle. If the speakers are too far apart
relative to the listener, some imaging can be lost. Refer to
figure 19.
