In-Ceiling Architectural Loudspeaker
Instruction Manual
LOUDSPEAKER PLACEMENT FOR DISTRIBUTED 
SOUND
 
s  Since distributed sound is general sound throughout an area, place 
the loudspeakers as uniformly as possible for even sound coverage 
throughout the area.
 
s  Place the left and right loudspeakers roughly the same distance 
from the primary listener locations.
 
s  To avoid “hot spots” where the sound is too loud, plan to use more 
loudspeakers, with each set to play at a lower volume.
LOUDSPEAKER PLACEMENT FOR TWO-CHANNEL 
STEREO
Place the left and right loudspeakers the same distance from the 
primary listening area (or as close to the same distance as possible). The 
distance from each speaker to its nearest side wall should also be the 
as close to the same distance as possible.

Ideally, the distance between the left and right loudspeakers should be 
slightly less than their distance from the primary listening area.
LOUDSPEAKER PLACEMENT FOR HOME THEATER
 
s  The front left, center and front right loudspeakers should be 
centered relative to the video display.
 
s  The front left, center, and front right loudspeakers should be closer 
to the video display than to the main listening area. For example, 
if the video display is 10 ft (3m) from the main listening area, the 
loudspeakers should be 6 ft (1.8m) or further from the main listening 
area.
 
s  The front left and front right loudspeakers should be relatively close 
to the sides of the video display. For example, front left and front 
right loudspeakers used with a 50-in (1.2m) video display should 
generally not be more than 80 in (2m) apart.
 
s  The center loudspeaker should be aligned with the center of the 
video display.
 
s  The surround-channel loudspeakers should be as far from the main 
listening area as possible but at least 2 feet (0.6m) from side and 
rear walls.
5.1-Channel Speaker Placement
 
s  In a 5.1-channel system, the surround left and surround right 
loudspeakers should be located directly to the sides of, or up to  
10 degrees behind, the main listening area.

degrees behind, the main listening area.
 
s  In a 7.1-channel system, the surround back left and surround back 
right loudspeakers should be equidistant from the primary listening 
area and generally as far from it as possible but at least 2 ft (0.6m) 
from the side and rear walls.
