AudioQuest BLACKLAB12M 39.4 Feet Black Lab Subwoofer Cable
Features
- Solid Long-Grain Copper (LGC) Conductors
Solid conductors eliminate strand-interaction distortion. Black Lab's solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding "loss" without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively 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 Foamed-Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials. - Metal-Layer Noise Dissipation System (NDS)
100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment's ground reference requires AQ's Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment's ground plane. - Symmetrical Coax Geometry
Identical + and – conductors prevent the shield being used as an inferior audio conductor - Cold-Welded Gold-Plated Plugs
This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of machinability - Grounding
Sometimes there is a hum problem unless the subwoofer and AV receiver (or surround-sound processor) are attached to each other using a separate wire. If your system has a hum problem, try attaching the little spade-lug tails to the metal chassis of the subwoofer amplifier and to the chassis of the sending component. Usually, this extra wire will not be needed - 12 Meter (39.4 Feet)

Frequently Asked Questions
-
The cable uses Solid Long-Grain Copper (LGC) conductors, which provide smoother and clearer sound compared to regular Oxygen-Free High-Conductivity copper (OFHC). LGC has fewer oxides, less impurities, and better performance, reducing distortion.
-
Foamed-Polyethylene insulation is used, which is air-filled and absorbs very little energy, minimizing signal loss and distortion. This low-loss insulation helps maintain a clear and focused audio signal.
-
The cable incorporates a Metal-Layer Noise Dissipation System (NDS) that prevents radio frequency interference (RFI) from modulating the ground reference, significantly reducing unwanted noise and hum in audio systems.
-
Cold-welded gold-plated plugs create distortion-free connections without solder, which can introduce distortion. The gold plating ensures excellent conductivity and resistance to corrosion, providing reliable long-term connections.
-
The cable is 39.4 feet (12 meters) long and features a black and white finish, making it visually distinct and easy to manage within audio setups.
