AudioQuest Irish Red RCA Male to RCA Male Subwoofer Cable - 6.56 ft. (2m)

AudioQuest Irish Red Subwoofer CableSolid 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: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. 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): 100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment?s ground reference requires AQ?s Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment?s ground plane.

Symmetrical Coax Geometry: Identical + and ? conductors prevent the shield being used as an inferior audio conductor.

Cold-Welded Gold-Plated Plugs: This plug design allows for a connection devoid 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.

Ground: Sometimes there is a hum problem unless the subwoofer and AV receiver (or surround-sound processor) are attached to each other using a separate wire. If your system has a hum problem try attaching the little spade-lug tails to the metal chassis of the subwoofer amplifier and to the chassis of the sending component. Usually this extra wire will not be needed.
