AudioQuest 20.0M IRISH RED SUBWOOFER cable

Solid .5% Silver-Plated Copper Conductors: A superbly cost-effective way to maximize a video or digital cable, harsh and horrible for full-range audio, but like turning up the “sharpness” for a subwoofer, enhancing articulation and intelligibility.

Metal-layer noise-dissipation

It's easy to accomplish 100% shield coverage. Preventing captured radio-frequency interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation. Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. Noise-Dissipation "shields the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.

Symmetrical coax geometry

Identical positive (+) and negative (-) conductors prevent the shield from being used as an inferior audio conductor.

Cold-welded, gold-plated terminations

This plug design allows for a connection devoid of solder, which is a common source of distortion. Instead of solder, the process employs a high-pressure technique. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.

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. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
