AUDIOQUEST Black Lab Subwoofer Cable

Connect amplifiers, receivers, soundbars, and AVRs to a variety of subwoofers with the AudioQuest Black Lab RCA Subwoofer Cable. Crafted with Solid Long-Grain Copper (LGC) conductors to minimize distortion, Foamed-Polyethylene insulation to preserve dynamic contrasts, and a Metal-Layer Noise-Dissipation system to efficiently dissipate high-frequency noise, this cable ensures a cleaner, more natural sound with powerful, clear bass and crystal-clear dialogue.

Solid Long-Grain Copper (LGC) Conductors
Solid Long-Grain Copper (LGC) offers a smoother, clearer sound compared to traditional Oxygen-Free High-Conductivity (OFHC) copper cables. By using solid conductors, strand interaction—the primary cause of distortion—is eliminated. The surface quality of the conductor is crucial, acting as a rail-guide for both electric fields within the conductor and magnetic fields outside. LGC has fewer oxides, fewer impurities, and less grain boundary interference, delivering superior performance and minimizing distortion for a purer, more accurate audio experience.

Metal-Layer Noise-Dissipation
Achieving 100% shield coverage is simple, but preventing captured radio-frequency interference (RFI) from affecting the ground reference is where AudioQuest’s Noise-Dissipation technology excels. Traditional shield systems absorb and drain noise/RF energy to the component ground, distorting the critical ground plane and, in turn, distorting the signal. AudioQuest's Noise-Dissipation technology "shields the shield," using alternating layers of metal and other materials to absorb and reflect most of the noise/RF energy before it reaches the ground, preserving signal integrity and enhancing audio clarity.

Foamed-Polyethylene Insulation
Any solid material next to a conductor can impact the signal, as it becomes part of an imperfect circuit that absorbs and releases energy, causing distortion. Foamed-Polyethylene (Foamed-PE) insulation, with its high air content, offers a solution. Since air absorbs very little energy and Polyethylene has a low-loss, benign distortion profile, this insulation minimizes the out-of-focus effects typical of other materials, ensuring the signal remains clearer and more precise, preserving the full dynamic range.

Symmetrical Coax Geometry
The use of identical positive (+) and negative (-) conductors ensures that the shield is not relied upon as an inferior audio conductor. This symmetrical design minimizes distortion, maintaining the integrity of the signal path and delivering a balanced, high-quality audio performance by preventing the shield from interfering with the signal transmission.

Cold-Welded, Gold-Plated Terminations
This advanced plug design eliminates the use of solder, which is a typical source of distortion in audio connections. Instead, a high-pressure technique is employed to form the connection, preserving the integrity of the signal. The ground shells are stamped rather than machined, allowing for the selection of metals specifically chosen for their low-distortion properties, ensuring optimal signal transfer without introducing unwanted interference. The gold plating further enhances conductivity and durability.
