AudioQuest Greyhound Subwoofer RCA Cable (12m Single)

The AudioQuest Greyhound sits one step above the Black Lab in AudioQuest's subwoofer cable range, introducing solid 0.5% silver-plated conductors in place of the Black Lab's unplated Long-Grain Copper. Above the Greyhound, the Irish Red adds a braided nylon jacket and further refined conductor geometry, while the Husky moves to solid 5% silver conductors. The Greyhound is designed for a single purpose: carrying a low-frequency signal from an AV receiver, integrated amplifier, or preamplifier to a powered subwoofer via a single RCA connection.

Conductor & Dielectric

The Greyhound uses solid 0.5% silver-plated conductors. Silver plating provides the high-conductivity surface properties of silver where they matter most (the signal-carrying skin of the conductor) while retaining the cost-effectiveness of a solid copper core beneath. Because the conductor is solid rather than stranded, strand-interaction distortion is eliminated entirely.

Both conductors are insulated with foamed polyethylene (PE). AudioQuest uses this material because air absorbs next to no energy, and the foaming process introduces air pockets within the polyethylene, reducing dielectric absorption. The result is lower timing errors and less smearing of dynamic contrasts compared to solid plastic dielectrics.

Geometry & Shielding

The cable employs AudioQuest's Hyperlitz Coaxial geometry: eight negative conductors spiral around a single, larger positive conductor. This arrangement creates a large cross-sectional area that minimises the effects of skin effect while maintaining low resistance across the full length of the cable.

A Metal-Layer Noise-Dissipation System (NDS) provides 100% shield coverage, absorbing and reflecting radio-frequency interference before it can reach the signal conductors. Rather than simply draining RF noise to ground (which can modulate the equipment's ground-reference plane), the NDS effectively shields the shield, preventing high-frequency noise from masking low-frequency detail.

Termination

The Greyhound is terminated with cold-welded, gold-plated RCA plugs. AudioQuest uses a high-pressure cold-welding process rather than solder, which they identify as a common source of distortion in cable terminations. The ground shells are stamped rather than machined, a choice made to minimise distortion. Gold plating ensures a corrosion-free, long-lasting connection.

Installation

The Greyhound carries a CL3/FT4 fire rating, making it suitable for permanent in-wall installation where local building codes require fire-rated cabling. It is available in seven lengths from 2m to 20m, covering both short-run and long-run subwoofer installations.
