This Star Quad speaker cable is assembled with four internal conductor wires which are each constructed with 11 AWG, stranded annealed copper conductors.

Annealing is a heat treating process that makes copper wire flexible and it also improves its conductivity -- the ability to send electronic signals through the wire. The internal copper wire conductors used to construct this audio cable are made up of individual thin strands that are bundled together to form one larger copper conductor wire which is then covered with insulation. While standard audio cables typically have two internal conductors, Star Quad cable is constructed with four separate conductors, each made up of bundles of stranded copper wires and insulated. The four-conductor construction of Star Quad cable is used to deliver a strong audio signal with high-quality sound that is free of external noise.
