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.
