INCRECABLE iSOUND DUO Twisted Pairs 4N OFHC 12' (foot) High End Speaker Cables

Also available in 8/10/12 foot lengths

Proudly manufactured in USA

From the manufacturer:
Minimize inductance by grouping the conductors as multiple twisted-pairs. The pairs are connected so that the current in first conductor of each pair runs in the opposite direction from the current in the second conductor. The magnetic field coupling between the twisted-pairs reduces the inductance, making it lower than the self-inductance of the wires themselves. Twisted pair cabling is a type of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from Unshielded Twisted Pair (UTP) cables, and crosstalk between neighboring pairs. Twisting the wires in a cable improves the cable's ability to reject external noise. It also reduces the cable inductance and may be the most effective way to keep the individual wires from vibrating with respect to each other.
