The Straight Wire Pro SC Banana to Banana 8" Speaker Cables are used to connect power (amps, receiver) to speakers. They carry both signal change and power compared to interconnects which only carry signal change. Premium speaker cables should be designed with abundant high quality conductors and insulation to maintain signal integrity and have low enough resistance to not limit current flow. Most premium speaker cables have multiple insulated conductor groups in a non parallel configuration to minimize and control electromagnetic and electrostatic distortions. Length, power and sonic tendencies of related components and the room environment should be considered in the selection process. Termination options include gold plated spades, banana plugs and pins as well as silver solder tinned ends.
