Harmonic Technology’s Pro-11 Reference speaker cable is a major improvement from the Pro-11 Plus speaker cable. The cable continues to integrate 11 AWG Single Crystal (OCC) Copper wires, but includes a similar structure to our award-winning Pro-10 Reference speaker cables with the Teflon tape wrapped around PE, PP and PVC insulations. In addition, the Pro-11 Reference leverages more than one-half inch outer construction with 8 subgroups of 20-24 AWG OCC copper wires to create an even richer and full-bodied signature soundstage.
