The AudioQuest Black Lab Sub Cable has been designed specifically for subwoofers and features a unique grouding cable to minimise hum.

Unique grounding cable

In most cases this won't be needed but if you suffer excessive hum from your subwoofer, then the Black Lab should be able to help. By connecting the ground cable to the metal chassis of your sub and the ground on your amp, earth hum problems should be solved.

Solid-core conductors for low distortion
For many years Audioquest has advocated solid-core rather than multi-strand cables. Electrical and magnetic interaction between strands in conventional cables can cause distortion, giving an unnatural edge to the sound and picture. Using Long-Grain Copper, the Audioquest Black Lab gives a cleaner, clearer sound than regular cables using OFHC (Oxygen-Free High-Conductivity) copper, thanks to fewer impurities.

Air-filled foamed-polyethylene insulation
Wire insulation can cause an imperfect signal by absorbing energy and then releasing it as distortion. The Black Lab uses air-filled Foamed-Polyethylene as air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. The result is reduced distortion for an even purer sound quality.

Cold-welded, gold-plated plugs
By using a high pressure weld rather than solder, there's less chance of a faulty connection between cable and plug. Not only does this lead to a more reliable connection in the long term but it also ensures low resistance and, hence, low distortion connection for the entire life of the cable.

Treat your subwoofer to a cable that's designed to get the best from it - the AudioQuest Black Lab.

Rated 4 out of 5 by from Good Quality Cable Bought this to resolve a “hum” issue with my subwoofer to my new AV receiver when connected via trigger cable. Unfortunately it didn’t solve the issue. Nevertheless, a good quality cable if a tad expensive, and usual excellent service from Richer Sounds.

Rated 5 out of 5 by from Amazing customer service Bought speaker cable and a sub cable. Didn’t know what to buy. Advice provided during lockdown was top class along with the customer service received on the agents day off!!!

Rated 3 out of 5 by from It works but expensive for this connection. This high tech phone to phone 3m connection is unlikely to have any noticeable improvement over any similar low tech one. The fidelity of the frequency range is uncompromised by using a basic shielded coax connection and employing linear oxygen free copper will be impossible to demonstrate any change.

Rated 5 out of 5 by from Perfect surround cable. Having had a quick look online for a suitable cable for my surround system and specifically my sub woofer, I decided to go for the AudioQuest Black Lab Sub 3m based on existing reviews. My original cable was unfortunately too short for the new setup. I checked various suppliers and found Richer Sounds to be the best in terms of price including delivery and were a name I knew I could trust having bought from them previously. The cable turned up in a matter of days and was a simple connect to amp and then sub woofer. The cable comes with an additional spur cable to reduce hum and was easy to connect via screws on each device. The sub woofer is now producing a great range of bass without feedback and was worth every penny.

Rated 5 out of 5 by from Just taken in a Black Lab! Having just upgraded my subwoofer to a Bowers and Wilkins, I thought it only fair to upgrade the audio cable. Having a 5.1 set up and listening to a lot of cds in good old-fashioned stereo I must say I'm very impressed with the Black Lab "GOOD BOY!"

Rated 5 out of 5 by from Superb sound quality when paired with Rel T Zero I bought this cable together with a Rel T Zero subwoofer from Richer Sounds Brighton at the beginning of the month. The sound of this pairing with my Ruark Audio MR1 MK2 speakers was astounding! The service from Damien (manager of the Brighton store) was world class. Highly recommend the technology and the store. It doesn't get any better!

Rated 5 out of 5 by from Great upgrade This is my second black lab cable as I have one on an another system, it proved to be a great upgrade from the standard cable that came with the sub, when I got my second sub it seemed only sensible to get another black lab. Well worth the little extra for great reward.

Rated 5 out of 5 by from Eliminated an annoying hum from my sub Having tried other possible solutions to an annoying hum my sub-woofer had developed without any success I was beginning to be at my wits end. Then I tried this as a last resort before trying out buying a new sub-woofer. Delighted to report it has cured the problem - I can enjoy my music once again!

Rated 5 out of 5 by from The very best Sub Cable. I had to buy a better Sub to go with my new Amplifier. Whilst in Richer Sounds I was advised, and rightly so, about Audioquest's Black Sub Cable. I am glad I took the advice. Easy to connect and, Out and IN, from Amp to Sub. This Sub cable enhances those rumbles and really low sounds a treat. To me a whole new sound experience.
