Product Research
Features
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.

This cable reduced about 95% of the subwoofer humm. The only way I can hear a slight humm is if I turn the gain to max, I have a 15 inch Rythmik sub and max is unnecessary. I strongly recommend buying this cable.
