AudioQuest - AudioQuest - William Tell Bi-wired Zero w/ Bass Speaker Cables (Pair)

AudioQuest's William Tell Bi-Wire speaker cables with RF/ND-Tech is an ideal cable for the Bass and Midrange inputs of either a Bi-Wireable or Tri-Wireable speaker when used in combination with William Tell Zero or William Tell Silver Full-Range cables.

The William Tell Bi-Wire speaker cables are Cold-Welded to AudioQuest’s extremely pure Red Copper Spades or Bananas. The bare copper is submerged in a vat of pure silver instead of being tumbled in a lower-grade solution. AudioQuest speaker breakouts and plug casings are not metal in order not to induce RF Noise into the conductors.

“Together with the various designs and method of assembly, they ultimately offer an unexpectedly good price-performance ratio. Taking into account a (very important) optimal system synergy, these cables can push the boundaries of what was once dreamed into real life."

Though a cable’s ground leads are integral to a component’s signal transmission, they also act as an antenna. Thus, they are subject to induced Radio-Frequency (RF) noise. RF noise is a parasitic signal that is typically coupled directly into a system’s most sensitive audio/video circuits. AudioQuest’s RF-on-ground Noise-Dissipation (RF/ND-Tech) greatly reduces resulting distortion and signal masking, yielding unprecedented levels of Noise-Dissipation across the widest bandwidth of radio frequencies possible. Their unique circuit topology uses a common-mode phase-cancelling array, providing linear noise dissipation across the entire length of the cable.

The only complete way to eliminate characteristic-impedance mismatches between a cable and the attached source and load is for the cable not to have any fixed characteristic-impedance value. Zero-Tech accomplishes this by eliminating interaction between the insulation and the cable’s conductors—enabling uncompressed current transfer. All-important transient current is unrestricted, and RF Noise-Dissipation is linearized.

All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest William Tell speaker cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. In AudioQuest's William Tell Bi-Wire speaker cables, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance.

Today’s environment is saturated with radio-frequency noise that is extremely difficult to filter or reject. The frequencies of this noise from satellites, cellular towers, and Bluetooth, etc., are so extremely narrow that a conventional shield, or a series or shunt filter, is wholly inadequate. Much of the low-level signal that carries the harmonics and spatial cues that define high-resolution audio is masked by induced radio-frequency noise. AudioQuest's comprehensive Linearized Noise-Dissipation System combines multiple shields and a carbon-based linearized resistive network that turns most of this noise into heat. 

When possible, running separate cables to the treble and bass halves of a speaker significantly reduces distortion. Bi-Wiring keeps the large magnetic fields associated with bass energy out of the treble cable, allowing the delicate upper frequencies to travel a less magnetically disturbed path, like taking the waves out of the water when you swim. AudioQuest’s RF/ND-Tech (patented RF-Canceling Ground-Noise Dissipation) attracts RF energy away from the amplifier’s output. When properly implemented, Bi-Wiring has always been a cost-effective way to get better performance for the same or less money.
