Our take on the AudioQuest Black Lab

by Steve Kindig
AudioQuest

Help your subwoofer sound its best

AudioQuest Black Lab

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

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.

Go Bye-Bye Hum

Written By BUBS, Charlottesville, VA on Monday, June 23, 2014
 
A few months ago I purchased a powered sub-woofer (from Crutchfield). After hooking up to an old sub-woofer cable which ran ~ 35 feet under my living room, I noticed a hum in certain locations of the room. With the advice of my Crutchfield salesperson, I began adjusting the amount of gain and low pass frequency on the new sub-woofer. This seemed to work on and off for a few days. However, since this humming annoyance continued to repeat itself, my salesperson had me examine the old cable and I noticed the end from the receiver differed from the end going to the sub-woofer. This wiring had been installed by someone else and there was a short extension cable at both ends of the sub-woofer cable to meet the distance required! So my salesperson had just the answer with this 39.4 foot Audio Quest Black Lab cable. Since then I have thoroughly enjoyed great bass and freedom from hum! ZILCH! I also think the price for this lengthy cable was very reasonable and I might add even better with some reward points!
Pros:
Not bulky or "stiff" so easy to thread through a small hole to run beneath a floor and be out of view. Allows for a clean and "healthy" bass sound with no hum or interference.
Cons:
None to date.
