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): 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. GROUNDING: 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.
