Semi-Solid Concentric Perfect-Surface Copper (PSC) and Long-Grain Copper (LGC) Conductors
In a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction is compounded as each strand changes position within the bundle. In an AQ Semi-Solid Concentric cable, strands within the bundle maintain their fixed relationships, significantly reducing distortion. A carefully finessed blend of Perfect-Surface Copper (PSC) and Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. 

Double Spiral-Pair Geometry
A typical speaker cable with parallel conductors has fairly high inductance, smearing energy across time, which results in sound that is dull and unfocused. In Rocket 11/22, the two conductors in each half of the cable are twisted around one another, providing lower inductance, greater clarity, and superior bass-to-treble frequency extension
