Flush-Mount Loudspeaker Placement - Bose FreeSpace 6 Installer's Manual

1.0 System Placement

1.3.2 Flush-mount loudspeaker placement

It is important to take a few minutes before installing the system to determine loudspeaker placement. The placement
of these loudspeakers is dependent upon the following factors:
• Ceiling height
• Listener ear height
• Desired smoothness of coverage
• Ceiling type (see Section 1.4)
Proper loudspeaker placement provides enjoyable sound no matter where you are in the area. Follow these steps to
determine the proper loudspeaker placement locations.
1. Begin by estimating the maximum ear height of the listener. For example, in a retail environment, patrons will most
likely be standing. Maximum ear height in this case will probably be about 6 feet. In a restaurant, patrons will be
seated and ear height may be 4 feet.
Note: The shorter the ear height, the broader the sound beam area. This means that the loudspeakers are placed
farther apart. Conversely, the higher the ear height, the narrower the sound beam area. The loudspeakers are placed
closer together.

2. Create a floor plan sketch of the installation site. Use the following formulas and table to determine loudspeaker
placement.
Use this formula to determine loudspeaker beamwidth height (H).
In this example, the room is 36 feet (11 m) x 36 feet (11 m) with a 10 foot (3 m) ceiling.

ceiling height - ear height = loudspeaker beamwidth height (H)
10 feet (3 m) - 4 feet (1.2 m) = 6 feet (1.8 m)
