i use flat cable for my surrounds, but it's not tape wire. I accidentally bought some Acoustic Research self adhesive tape wire, and it was really awful to work with and tried to pull the tape off the walls. I got the flat cable instead (16 gauge), along with some double sided foam tape, and that looks pretty darn good, if I say so myself. It also doesn't pull paint off the wall.

I am the Doctor, and THIS... is my SPOON!
