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 41 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.Primary InformationCable Type : Speaker cable Left Connector Type : Bare wire Right Connector Type : Bare wire Dimensions&MiscellaneousLength : 500 feet Color : White Service&SupportService & Support Type : Limited Lifetime Manufacturer Warranty UNSPSC CodeUNSPSC Code : 26121620
