SPEAKER PLACEMENT
Before installing your speakers you should consider the placement carefully, taking into account the location electrical,
pluming, and other fixtures. Contact your SpeakerCraft dealer for assistance if you are not sure of the best location in your
particular room environment.
Placement in ceiling: Before mounting your BAS speakers you should consider what affects the room (and the location of the
speaker in that room) will have upon the amount of bass augmentation you wold like to achieve. You many want to consider
the location of the satellites as well since the same principles will apply to the bass from those speaker.
The music we hear as bass is made up of frequencies that have long to very long wavelengths (6ft. to 50ft.). Therefore when
a speaker is placed into a room, its position in the room will affect the amount of bass perceived by the listener. In other
words placing the speaker in some area of a room will result in more bass than in other areas of the same room. The more
surfaces (wall, ceiling, floors) a speaker is placed next too, the more bass you will hear. An in-wall/in-ceiling speaker mounted
in the center of a wall (or ceiling) will gain 3dB of bass if it is moved up the wall (across the ceiling) to where it is adjacent
to the ceiling (wall). You can then gain 3dB additional bass by moving the speaker to the corner, where the intersection of
three surfaces occurs.
The result is that a speaker placed in a corner will have up to 6dB more apparent bass than the same speaker mounted in
the center of a wall or ceiling.
INSTALLATION CONSIDERATIONS
Prior to the actual installation of the speakers, it will be necessary to run cables to the speaker location. See your Authorized
SpeakerCraft dealer for more information on cable installation. After the cable has been installed, you are ready to mount
the speakers.
Preparation for and mounting of the speakers can happen at two different stages. If you are building a new ceiling, follow
the section titled INSTALLATION PREPARATION - NEW CONSTRUCTION. If you are placing the speakers into an existing ceiling,
follow INSTALLATION PREPARATION - FINISHED CEILING. There are different considerations for each application. Please care-
fully follow the recommendations for your application.
INSTALLATION PREPARATION - NEW CONSTRUCTION
When installing the speakers into a newly built ceiling, please follow these instructions carefully:
1. Determine Placement
