Choose a smooth surface on which to hang the speakers. Picture hooks will not properly adhere to rough surfaces such as brick, fabric or textured paint.
Wash the area thoroughly with rubbing alcohol, using a clean rag. The rubbing alcohol will remove grease and dirt that could interfere with adhesion. Allow the area to dry thoroughly before proceeding.
Remove the adhesive backing from one of the picture hooks. Press it on the clean area of the wall firmly but carefully.
Hang the speaker from the hook.
Repeat the entire process for each speaker you need to hang.
