The Audio Quest Greyhound Subwoofer Cable is designed specifically for custom-installation projects boasting a thin & discreet design. This makes it incredibly convenient for running behind walls in ceiling voids & other tight spaces. The Hyperlitz Coax Geometry of the cable is ingeniously structured with eight negative conductors spiralling around a larger positive conductor resulting in a larger cross-sectional area while maintaining a slim overall cable diameter. For installers this cable is a dream come true. In addition to this the conductor material itself is made out of 0.5% Silver increasing its efficiency which results in a more direct sound & impactful that is really noticable on subwoofers.
