Installing the SI 3 Speakers
The Extron SI 3 speakers can be mounted on a surface, such as a
wall or post, or mounted in a bookcase, or on a shelf, and can be
used with any Extron product supporting audio.
N If the speakers are to be placed on a horizontal surface such
as a desk or shelf, attach the back cover to enhance the
speaker appearance.
