AudioQuest’s Flat Series speaker cable is built around a Semi-Solid Concentric design. While this is not as transparent as AudioQuest’s Solid-Core Conductors, Semi-Solid wire is significantly more resolved than conventional stranded bundle wire.
SEMI-SOLID CONCENTRIC PACKED CONDUCTORS: Semi-Solid Concentric Packed Conductors are used in some of AudioQuest’s AC power and speaker cables as a cost-effective, flexible alternative to typical stranded conductors. Semi-Solid Concentric Packed Conductors use fewer, larger strands that do not change position down the length of the cable. While solid conductors are the complete solution to strand distortion, Semi-Solid Concentric Packed Conductors avoid many of the distortion mechanisms of stranded conductors.
LONG-GRAIN COPPER (LGC): LGC allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding "loss” without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. G-2 cables use LGC strands in a Semi-Solid Concentric Packed Conductor arrangement.SPREAD-SPECTRUM TECHNOLOGY (SST): Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any conductor of a particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors.
