Halo 2 Speaker Cable Halo 2 is a 9 AWG pure silver hybrid speaker cable that draws on many of the design concepts of our reference-grade speaker cable designs. The 12 solid-core conductors per channel feature 'distributed gauge' technology to optimise bandwidth and frequency response. The insulation is our super air-spaced PTFE Teflon dielectric and the conductor groups are arranged in a counter-balanced helical-twist geometry. Two resonance dampers per channel help to reduce mechanically-induced distortions. Halo 2 has a sweet and natural sound with richly detailed voices, solid bass extension and a deep, three dimensional soundstage.
