AudioQuest Black Lab 2m RCA Subwoofer Interconnect – Solid Long-Grain Copper, Foamed-Polyethylene Insulation, Noise-Dissipation System

SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS: Experience superior sound with our subwoofer interconnect cable, featuring Long-Grain Copper conductors that reduce strand-interaction distortion, outperforming regular OFHC (Oxygen-Free High-Conductivity) copper cables. OFHC focuses on minimizing energy loss without addressing the issue of sound clarity. Our LGC conductors have fewer oxides, less impurities, and fewer grain boundaries, ensuring a more precise audio transmission.

FOAMED-POLYETHYLENE INSULATION: The materials near a conductor play a significant role in the overall performance of the cable. Wire insulation and circuit boards can store and distort the energy they receive. Our Foamed-Polyethylene Insulation minimizes energy absorption and distortion, providing a more accurate representation of your music. The polyethylene used is known for its benign effect on sound, and the air within the insulation absorbs virtually no energy, reducing the ‘out-of-focus’ sound often present with different insulation materials.

METAL-LAYER NOISE-DISSIPATION SYSTEM (NDS): Achieving comprehensive shield coverage is straightforward; the key challenge is stopping it from causing issues. Our Noise-Dissipation System is engineered to prevent captured RF Interference from modulating your device’s ground plane, thus protecting your audio equipment from unwanted noise.

SYMMETRICAL COAX GEOMETRY: By making the positive and negative conductors identical, we prevent the shield from acting as an unintended audio path, thus maintaining the integrity of your sound.

COLD-WELDED GOLD-PLATED PLUGS: The connection method used in our plugs avoids a significant potential flaw: solder-induced issues. The stamped ground shells allow us to select metals based on their sonic properties, not just their ease of machining, further reducing potential sound degradation.

GROUNDING: In some configurations, a separate grounding wire between the subwoofer and AV receiver (or surround-sound processor) is required to eliminate hum. If you experience this problem, attaching the provided grounding tails to the metal parts of the respective devices usually rectifies it, though often this step is unnecessary.
