Speaker Placement
Careful consideration should be made when determining the desired location of this speaker. As these are referred to as ceiling
speakers, this is the intended mounting location. However, there is no electronic or physical reason these cannot be mounted
in other locations. Note that careful consideration should be given to appearance in these situations.
Following are some typical guidelines that should be followed when determining the optimum placement for speakers in a given
environment. Note that these are guidelines. Aesthetics, light fixtures, ceiling fans and similar items will also require
consideration, and should be considered equally important to the recommendations below.
Unique Single Point Stereo™ Feature
This speaker incorporates a unique Single Point Stereo™ design, which allows it to be connected to both the left and right
channel of an amplifier, while retaining complete channel isolation. This is perfect when sound is desired in small areas, such as
entryways, small lavatories, hallways and similar areas, where location of two speakers may not be desirable. This speaker will
ensure that both the left and right channels are heard from a single point, without compromising left/right channel isolation in
other listening zones.
Whole House Audio Listening
Given a typical rectangular room, the ideal ceiling placement for these speakers is depicted below. When installing a single
speaker in a given room, the optimum placement is directly in the center. When installing a pair of speakers, bisect the room in
both the long and short dimensions. This will provide an exact center point. Then along the long length, bisect each half.
Where each of these bisected lines cross the center point, is the optimum speaker location.
Since these speakers are mounted in a 15° offset frame, it is also recommended that the location be shifted from the center
line displayed above. With an 8' ceiling, the shift is 8" from center. With a 10' ceiling, the shift is 14.5" from center, and with a
12' ceiling, the shift is 19" from the center line of the ceiling.
It is important to note that more speakers in a given listening area do not necessarily equate to higher sound levels. With more
speakers, the desired listening level for a given area is attained with lower output from each speaker. This creates a much
more pleasant listening environment as the sound source can be uniformly heard through the entire room, regardless of
location and with less interference with sounds such as conversation.
