Installation - McIntosh XR100 Owner's Manual

Installation

Loudspeaker Placement
Loudspeaker placement in a room can greatly affect
performance. The XR100 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 en-
viromental 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 is 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 over all musical balance in the sound
and the bass content does not dominate.
The XR100'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 9.

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 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 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 11.
