Features: RockvilIe RCSS14-25 14 AWG 2-Conductor SpeakON to SpeakON Pro Speaker Cable. 100% Copper Conductors for Lower Resistance. Black PVC Jacket for Both Durability and Flexibility. Intended for High-Current Applications Only, Not Line-Level Signals. Length: 25 Ft. Gauge: 14 All RockvilIe pro audio cables are made with 100% copper which boosts theefficiency of the cable. There is nothing better than 100% copper. Most of thecheaper cables on the market do not use 100% copper, instead they make theircables with CCA (Copper Clad Aluminum). CCA cables do not perform on the levelthat 100% copper cables perform at. CCA will not conduct signals efficiently. A12 gauge CCA cable will not even perform as well as a 14 gauge 100% pure coppercable, which will in turn, affect the performance and longevity of yourequipment. If you find cables on the market that do not mention the coppercontent, there is a good chance that they are selling you a cheaper cable thatis CCA and not 100% copper. RockvilIe pays an inspe
