A friend of mine just bought a house and needs help with speaker wire It will be used for ceiling speakers so the wires will be in-wall. I read that it need to be sheild or something. I orginally planed to order from knuconeptz but the sheilded wires that they have cost a lot compared to partexpress. The only difference I see from knu and part. is that knu has over 200 strans while part. only have 19 strans for the same gauge wire. Will that make a difference in sq. All I know is the less strans the harder it is to bend.
