Black Lab. A subwoofer cable that eliminates distortion from beach interaction with solid copper conductors, the AudioQuest Black Lab subwoofer cable is ready to take on the challenge of your home theater. By using solid long-fiber copper (LGC), the Black Lab delivers a smoother, clearer sound that is superior to other cables that use ordinary oxygen-free highly conductive copper. The conductive material in LGC has fewer oxides, fewer impurities and fewer grain boundaries for definitively better performance.
- SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS Solid copper conductors eliminate distortion. Black Lab's solid Long-Grain Copper provides smoother, brighter sound than cables with ordinary OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding "loss" without any concern for distortion. LGC has fewer oxides in the conductive material, fewer impurities, fewer grain boundaries and certainly better performance.
- FOAMED-POLYETHYLENE INSULATION Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Black Lab uses air-filled Foam-Polyethylene Insulation on both conductors because air absorbs almost no energy and Polyethylene has a low loss and a benign deformation profile.
- METAL-LAYER NOISE-DISSIPATION SYSTEM (NDS) 100% shielding is simple. To prevent captured RF interference from modulating the equipment ground reference, the AQ Noise-Dissipation System is required. The Noise-Dissipation System prevents a significant amount of RFI from reaching the ground plane of the equipment.
- SYMMETRIC COAX GEOMETRY Identical + and - conductors prevent the shield from being used as an inferior audio conductor.
- COLD-WELDED GOLD-PLATED PLUGS This plug design allows for a connection without solder, which is a common source of distortion. Because the connections are stamped rather than machined, the metal can be chosen for low distortion rather than machinability.
- EARTHING Sometimes there is a hum problem unless the subwoofer and the AV receiver (or surround-sound processor) are attached to each other with a separate wire.
