Ratio speakers provide room-fi lling sound in any 
multiroom system with amplifi ed keypads. In many 
cases where an external amplifi er would be added for 
conventional speakers, a pair of Ratio speakers powered 
directly by the keypad will suffi ce.

Designed for optimal performance with amplifi ed key-
pad systems, Ratio speakers make it possible to use such 
systems in places where higher-powered systems would 
otherwise be used. This provides an economical alterna-
tive to high-powered multiroom systems.

Following are some general placement guidelines for  
stereo listening and background music applications. 
Other things to consider for speaker placement include:

•  Locations of unobstructed wall or ceiling cavities in 

which to mount the speakers

•  Accessibility for running cables through the walls or 

ceilings to the speaker locations

Speaker placement for stereo music listening is impor-
tant for proper imaging. Imaging is the ability of the 
speaker pair to reproduce sounds so they appear to 
come from between the speakers.

In a stereo music system, we recommend placing the 
left and right speakers about 60 degrees apart when 
viewed from the center listening position. In-wall 
speakers should be centered at ear level.

Speaker placement for background music is less critical 
than for stereo listening. Often the goal is to provide 
even coverage throughout the room, without regard to 
a fi xed listening position. In this case, the speakers can 
be placed so they cover equal portions of the room.

In other cases, the goal is to provide background music 
only in part of a large room or open area, often where 
the seating is located. In this case, the speakers can be 
located to provide coverage in that part of the room.

Placing the speakers near the corners of a room can 
help emphasize bass frequencies. This is fi ne if both 
speak ers in a stereo pair are mounted near corners, but 
avoid placing one speaker in a corner and another in a 
large open area.

The best acoustic performance will result if the speakers 
face the same type of surface and are placed in similar 
positions on the same type of wall or ceiling surface.

The RC61S stereo ceiling speaker is useful for providing 
coverage for a small room from a single point. Usually it 
should be placed near the center of the room.

Ratio indoor speakers are designed to provide reliable 
long-term service as long as they are not installed 
in wet or damp locations such as showers. Also, they 
should not be installed in areas continually subject to 
high humidity, such as unventilated bathrooms and 
porches in humid climates.
