AudioQuest Black Lab - RCA Interconnect Subwoofer Cable
High Performance Subwoofer Interconnect Cable
AudioQuest believes good cable design is all about damage control. In AQ's view, the perfect cable would be one that adds nothing — no noise, no distortion — to the original signal. Even AudioQuest's affordable Evergreen cables embody this philosophy. They bring together some of AQ's most advanced designs and materials, for excellent sound quality from a single joined cable that's relatively thin and lightweight.
Contrary to their name, Black Labs’ heritage actually traces back to Newfoundland in the 1700s, when they were first known as “Saint John’s Dogs.” When this large Newfoundlandbased breed was mixed with smaller water dogs, the result is the dog now known as the Labrador. Labradors (Black or otherwise) are known for their dedication to duty, their highly developed sense of smell and hearing, and their endless capacity for playing “fetch” (they are “retrievers” after all!). These traits combine to make Labradors excellent service dogs for the handicapped as well as wonderful pets.
It's easy to accomplish 100% shield coverage. Preventing captured radio-frequency interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation. Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. Noise-Dissipation "shields the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
SYMMETRICAL COAX GEOMETRY
Identical positive (+) and negative (-) conductors prevent the shield from being used as an inferior audio conductor.
COLD-WELDED, GOLD-PLATED TERMINATIONS
This plug design allows for a connection devoid of solder, which is a common source of distortion. Instead of solder, the process employs a high-pressure technique. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.
SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS
Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
