AudioQuest Irish Red

AudioQuest's Irish Red cable helps any powered subwoofer sound more realistic by minimizing any loss in the signal as it travels from your receiver to the sub. This cable features two identical solid conductors, and each conductor is a single, unbroken strand of AudioQuest's high-purity Long-Grain Copper, coated with silver. Solid conductors eliminate electrical and magnetic interference that can make multi-strand conductor cables sound brittle.

High-quality connectors eliminate the weakest link

Irish Red 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.

AudioQuest takes a lot of care and pride in every aspect of their cables, including their appearance. Irish Red cables come with a good-looking black-and-red braided covering for the shorter lengths (5 meters and under). Longer lengths use a smooth PVC jacket that's CL3/FT4-rated for in-wall use.

Product Highlights:

  • two silver-plated solid copper conductors for superior sound quality (silver layer is 0.5% of total conductor)
  • 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
  • black-and-red braided covering on lengths of 5 meters or less; 8-meter and longer lengths have a smooth PVC jacket
  • warranty: 5 years
  • Our 60-day money-back guarantee

Great cable!

Written by: Don from Nevada on December 6, 2015

Crutchfield Customer Review (What's this?)

Like everything AudioQuest makes, this is great cable . It won't radically change the sound coming out of your subwoofers, but the sound will be slightly smoother in quality, at least better than what I was getting out of the stock cables that came with my two JBL SUB250 subwoofers.

Pros: Nice looking well made cable.

Cons: Pricey just like everything else AudioQuest sells but then, you get what you're willing to pay for when it comes to electronics.

Nice looking cable. Silly me! I thought I was buying a pair. Only one arrived. I will update review after I buy another one.



AudioQuest subwoofer cable (Irish Red)

Written by: SandyU from Appling GA (near Augusta) on August 4, 2014

Crutchfield Customer Review (What's this?)

Crutchfield's good service, plus AudioQuest's high quality at a reasonable price (for cable). Maye you can go wrong there, but I can't see how. Can you?

Pros: Relatively inexpensive for what it represents Welded, not soldered (longer useful life) AudioQuest: A name and a company you can trust Crutchfield gives the best price on AudioQuest I could find

Cons: Well... You could buy more expensive stuff and maybe get better sound; but have you voiced your system yet? (HINT: Voicing your system will always do more for you than upgrading yours ICs and cables.)

Product Research


Solid 0.5% Silver Conductors: Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high-quality subwoofer cables.

Foamed-Polyethylene Insulation: Irish Red 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.
