    I see some conflicting info about the flexibility of this wire (especially the 12AWG). My plan is to run it in-wall, and then thru a brushed wall plate straight to my speakers. I don't intend to do anything fancy, but I might want to be able to angle it a bit from wall to speaker for my fronts. Exactly how rigid is this wire?

    Also, if I trim off the external jacket, does it have a second one inside that wraps around both wires? I saw a review indicating this but it seems strange.

    Jeffrey R on Apr 14, 2017
    BEST ANSWER: The wire has 2 layers of insulation, an exterior wrap and a wrap for each conductor on the interior. The wire is not rigid and is flexible as any stranded cable in my experience. It's slightly more rigid than lamp cord.
