About the AudioQuest Black Lab
Help your subwoofer sound its best
Help your subwoofer sound its best
AudioQuest's Black Lab cable delivers all the deep bass goodness your powered subwoofer is capable of. This cable features two identical conductors, and each conductor is a single, unbroken strand of AudioQuest's high-purity Long-Grain Copper. Solid conductors eliminate electrical and magnetic interference that can make multi-strand conductor cables sound brittle.
High-quality connectors eliminate the weakest link
Black Lab features RCA connectors made of gold-plated copper. The connectors are fastened by cold welding — a solder-less process that uses high pressure and silver paste to minimize signal loss. By contrast, solder tends to impede the signal, and heating the copper conductor can negatively affect its performance.
Product highlights:
- two solid Long-Grain Copper conductors eliminate "strand-interaction" distortion
- air-filled foamed-polyethylene insulation minimizes energy storage and its associated distortion
- 100% coverage metal shield with AQ's Noise Dissipation System to resist RFI interference
- cold-welded gold-plated RCA connectors for reliability and resistance to corrosion
- built-in ground wire with spade lugs to prevent hum
- smooth PVC jacket
- warranty: 5 years
- MFR # BLAB20
What's in the box:
- 65.5625" Mono-RCA subwoofer cable (w/ a male RCA connector and 8" ground wire on each end)

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: 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): AudioQuest's Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment's ground plane.
Symmetrical Coax Geometry: Identical positive (+) and negative (-) conductors prevent the shield being used as an inferior audio conductor.
Cold-Welded Gold-Plated Plugs: This plug design allows for a connection without the use 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: If you hear noticeable hum in your system after connecting your subwoofer, please attach the subwoofer cable's ground leads to your audio gear. Some audio equipment have a ground (GND) connection on the back-panel, if not, attach the ground spade lugs to any screw on the equipment chassis of both the source and the subwoofer. Usually, this wire will not need to be connected.

This is my second AudioQuest subwoofer cable purchase since I now have 2 subwoofers. My old one was a Monster cable which worked fine, but this is a little cheaper and feels like better quality. Also it is non directional, the ground wire is available in case of hum. Not an issue in my case.
