A Major (and Majorly Affordable) Upgrade from Stock Subwoofer Cables: AudioQuest Black Lab Reduces Timing Smears, Enhances Clarity, and Includes Noise Dissipation System While Black Lab happens to be AudioQuest's most affordable subwoofer cable, it'll trounce the performance of your stock or box-store coaxial interconnect.

The cutting-edge design significantly reduces timing smears that rob your subwoofer of the startling low-frequency impact it was made to produce. In addition, its air-filled polyethylene insulation improves focus to a degree that makes lesser cables sound fuzzy by comparison.

Built to work within today's electronically noisy environments, Black Lab holds annoying radio-frequency signals and equipment-generated electromagnetic interference at bay with AudioQuest's proprietary metal-layer Noise Dissipation System (NDS).

In addition, solid, long-grain (LGC) conductors remove strand interaction, resulting in greater sonic clarity and a more musical presentation.

Add to all that technological innovation Black Lab's low-distortion cold-welded plugs and a handy grounding tail to eliminate all-too-common hum problems, and you have a budget-friendly cable custom-designed to unleash your subwoofer's true potential. 100% Music Direct Guaranteed.

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.
