The AudioSource AST 220S and AST 220C were
specifically designed for use in a Home Theater system.
Additionally, this speaker system has been optimized to
enhance the total theater experience with flat panel
displays such as Plasma, LCD and DLP Projection and
Rear Projection displays.
The AST 220S is designed to be used as the satellite
speakers; left and right front as well as left and right side
or rear speakers. They are designed to be wall mounted
using the supplied brackets or they can be set up to be
table mounted utilizing the supplied bases. One pair may
be set up to be floor standing using the stands provided.
The AST 220C is the specifically designed for use as the
front center channel speaker and can be mounted to the
wall beneath the display using the mounting bracket
provided or it may be table mounted on any flat surface
using the Isolation Mounting Feet included with the
AST 220C. These feet were custom molded to fit the
bottom edge of the AST 220C and should be placed near
either end in a manner that is aesthetically pleasing to
the user. The molded surface has an adhesive layer that
can be exposed by removing the protective paper layer
once you have determined the placement of the feet for
your intended use.
Placement of the Brackets
The placement of the brackets for the left and right front
loudspeakers should considered from the point of
making the loudspeakers perform correct acoustically
while maintaining an aesthetically pleasing appearance.
The AST 220S has very wide dispersion characteristics
in the horizontal plane. Therefore, the AST 220S
loudspeakers may be mounted in close proximity to your
display or screen area. We recommend that you leave a
minimum of 2 to 3 inches between the edge of the
display or screen area.
Mounting the Wall Brackets
The wall mounting brackets are designed to be attached to
the wall surface using screws. Where no underlying wall
stud is available for proper placement it is highly recom-
mended that an appropriate wall anchor be used.
We do not recommend a particular type since many
different wall surfaces may be encountered. If you are
unsure as to which type of wall anchor to use consult with
your local Hardware or Do-It-Yourself store specialist to
determine the correct anchor for the type of wall surface in
your home.
Note: the weight of an AST 220S or an AST 220C is
7.1 pounds.
The wall mounting bracket has four slots to accept screws
for attaching it to the wall surface. If you are locating the
bracket over a wall stud these slots will fall within the width
of a standard 2x4 or 2x6 wall stud. There is a slot at the
bottom and in the middle of the bracket to allow the
speaker cable to be brought through both the wall and the
bracket to connect to the terminals on the rear of
the AST 220S and the AST 220C loudspeakers.

If you wish to extend the speakers beyond the 2” to 3”
minimum that presents no problem. Please note that the
distance between the right and left speakers should not be
greater than the distance from the speakers to the
listener’s position.
