This is the 8M (26' 3") Husky Subwoofer Cable with Braided jacket and RCA plugs SOLID 5% SILVER CONDUCTORS: Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications POLYETHYLENE AIR-TUBE INSULATION: All of Husky's conductors use PE Air-Tube Insulation because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. PE Air-Tube Insulation causes much less of the out-of-focus effect common to other materials. DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): The DBS battery packs will last for years. A test button and LED allow for the occasional battery check. CARBON-BASED 4-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. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment's ground plane. TRIPLE-BALANCED GEOMETRY: The 100% coverage shield is never used as an inferior conductor. COLD-WELDED HANGING-SILVER DIRECTLY OVER PURE RED COPPER SYSTEM: This plug design enables a perfect heat-free connection between cable and plug. The connection between the plug and conductors is made using AQ's Cold-Welded System, which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Welded System refers to a combination of high pressure at the point of contact and the use of silver-impregnated paste. 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.
