AST-Base Mounting Instructions
Assembling the Base to the AST 220S
To attach the “Base” to the AST 220S, use a Phillips head
screwdriver to remove the four screws from the bottom end
cap of the AST 220S speaker.
Place the open end of the speaker into the base. Replace
the four screws into the AST 220S. Start all for screws
before fully tightening.
Note: If the screws do not
seem to align properly with
the four channels of the
aluminum extrusion of the
AST 220S, loosen the four
Pan Head screws that retain
the steel plate to the bottom
of the “Base”. (Do not remove
these screws.) Re-align the
base of the extrusion and
tighten all screws. Be careful
not to overtighten the screws
and possibly strip the channel
to the point the screws will
not grip snugly.
