To get cabling to the ceiling speakers, I have access to the base of the angled ceiling drywall, in the crawl space behind the side walls of the room. Behind the walls of the angled ceiling is a thick layer of insulation inside clear plastic. The best way to get the this speaker wire from the base of the ceiling to the one inch hole behind the speaker, was to run it form the bottom to the top, not top down. Because the wire hole was only one inch, I didn’t have enough space to get my hand in their and push the cable downward, between the layer of insulation and the drywall. Gravity wasn’t enough to take the cable down the back of the wall by itself. 

I taped a three foot long string to a thin fiberglass push/pull rod, then taped the speaker cable to the string. I pushed the rod up the back of the wall, attaching additional extension rods as needed. Once the rod, string, and wire were close to the hole behind the speaker, I used a lighted steel claw mechanical pickup tool with a Depstech endoscope camera attached, to grab the string and pull it through the wire hole. This endoscope camera saved me a ton of time because the fiberglass rod never went straight up the back of the wall and stopped right next to the speaker wire hole. The camera sent live video to my iPhone as I fished for the string.
