    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: I used this wire to run 12 pair of speakers in my house. Never had any problem with flexibility. However, I ran it to banana plug wall plates so that I could plug my speakers into the wall, which I recommend so that you don't have wires hanging out if you move your speakers, but primarily to give you flexibility in wire length - and gauge - to your speakers. Some of my speakers won't take 12 gauge and sometimes I must run 4 ohm speakers in series. I would never run CL2 wire straight through the wall because it limits you too much. This is where you want to consider your "flexibility." Never even considered doing that. Want to rearrange your speakers and place them farther apart and you're stuck. Overall, this is the best wire I have ever found. Each wire within the outer covering is fully insulated. Don't understand any comment about a second overall covering. Do understand the comment about using it for his motorcycle! Above all, use banana plug wall plates!!! Do not run the wire - any wire - directly through the wall to your speakers.
