My HT is 23 feet long and my gear rack is in the back of the room. I have to run the speaker wire around 30 feet a strand. I will have three speaker wires and 2 subwoofer cables running all the way from the back of the room to the front. The sheetrock is already up and I'm putting acoustic fabric on the walls. It might be tough to get the wire in the walls because of the baseboard heating. I was thinking about using an external molding to hide the wires. Any suggestions would be appreciated.
