Installation
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
Chrome Glides. Both the
Glides and Tiptoes have a
threaded shaft and locking nut Tiptoes Glides 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.
Room Placement
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. Refer to figure
18.
