Room Acoustics and Loudspeaker
Placement
of the Loudspeaker of at least 30 degrees either side
from the center axis for the best performance. Refer to
figure 20.
Locating Loudspeakers for use in Home Theater
In a Home Theater application, the placement of Left,
Center 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 help-
ful as a starting place. Refer to figure 21.
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 22.
Room Acoustics and Loudspeaker Placement
Loudspeaker Placement
Loudspeaker placement in a room can greatly affect
performance. The LCR80 Loudspeaker System is de-
signed for 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.
Sometimes Loudspeaker placement in a room is
limited to locations with unacceptable perfomance.
McIntosh now offers a solution with several Electronic
Products offering the ability to precisely measure
and correct for room induced acoustical problems,
thus restoring proper musical balance. Contact your
McIntosh Dealer for more information about this new
exciting advance in sound reproduction technology.
If a McIntosh product with room correction is not
part of your system nor professional measurement of
your system performance been performed, listen to
the Loudspeaker. Try various locations by listening to
music containing continuous bass and find a location
where there is an over all musical balance in the sound
and the bass content does not dominate. Placement
near a wall, corner, floor, ceiling or any intersect-
ing 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.
The LCR80’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
