Hi Piobob
What type of walls
soild or stud.
if they are the same as the RSFX than no, not unless you recess them in the wall using the template provided, you could then use a eyelet with a screwed thread in the recess with the cable passing through the eye part, then connect the bannana plugs ( then if you remove the speaker and the speaker cable drops it will not drop to the bottom of the stud wall.
