I have some speakers I hope to run wires for from not much higher than switch height for my 7.1 system. I'm thinking I might be able to just drill a hole and use a coat hanger to get it started then push it down. I haven't done this work but my stud finder doesn't seem to indicate any blockage and there is a light switch panel in that area so I was thinking it might not be too bad.
The wall is a framed drywall wall against a concrete wall in a finished basement.
Do I need an expensive wire puller or will this approach work.
