After carefully unpacking your subwoofer, the carton an

To attach the feet to the subwoofer, lay it on its top with the 
speaker facing up. Remove the feet from their package and 
screw them into the pre-
drilled holes located on the bottom of the 
subwoofer with a screwdriver. Once the feet are tightly secured, 
place the subwoofer upright on its feet. 
If the subwoofer appears to be damaged, do not attempt to 
repair or connect the unit to the amplifier. If you have to return 
the subwoofer first remove the feet, then repack the subwoofer 
and notify your distributor or M&S Systems for replacement or 
repair.
