Installation
Figure 15
13. Attach the Column Base to the Loudspeaker Column
using the four supplied machine bolts and washers. Re-
fer to figure 12.
14. Orient the Loudspeaker Grille
with the extended wood trim
pointed towards the Column Base
and line it up even with top/sides
of the Column. Align the Grille
fastening pins to the Column
Grommets (there are six pins on
each side). Carefully push down
to secure the Grille to the Column. Refer to figure 13.
Optional Feet
15. Two sets of optional feet (fourteen Tiptoes and fourteen
Glides) are supplied with the XRT30 Loudspeaker Sys-
tem. Refer to figure 16. To
prevent crushing carpet use
the Tiptoe Spikes; to protect
non-carpeted flooring use the
Chrome Glides. Both the
Glides and Tiptoes have a
threaded shaft and locking nut
that screw into the tapped
holes in the bottom of the
XRT30’s base rails. The feet can be independently ad-
justed to compensate for uneven flooring. The second
set of optional feet are for the Bass Section Cabinet.
16. Stand the Column upright.

Loudspeaker placement in a room can greatly affect
performance. The XRT30 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 enviromental 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 dependant 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 until the lo-
cations that sound best are found.
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 17.
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.
