μ-4.1T is a 13 awg High End Bi-Wire speaker cable. This Bi-Wire speaker cable consists of different stranding configurations. The Blue and Black Treble wires uses a rope-lay stranding method. The White and Red Bass wires uses a concentric stranding method.
The 13 AWG α(Alpha) μ-OFC Conductor wire strands are treated with the Furutech's α(Alpha) process - super cryogenic and demagnetization treatment of all metal elements
