If you are planning to install audio throughout your house, this is the cable you'll need. Impact Acoustics in-wall speaker wire is made from 65 strands of 99.9% high-purity copper so it's very flexible and less likely to kink during installation. This cable is CL2 rated for use inside walls and features a flame-retardant jacket that helps to diminish the potential of fire spreading between floors. In-wall speaker wire features conductors twisted upon each other that makes the cable round and much easier to pull throughout the house than flat or zip-cord style speaker wire. Inner conductors are color-coded for easy identification.
