AudioQuest William Tell Zero Full-Range Speaker Cables

$4,999.00$7,499.00

William Tell ZERO speaker cables may be used in one of two ways: either as ideal Full-Range cables, or, in combination with a dedicated BASS cable, in a BiWire cable assembly of unparalleled performance.

Any AudioQuest Cables that are showing in stock at supplier will take 1 -2 weeks to ship. Custom lengths and termination are available, just reach out for a quote!

Price is for a pair of cables.

Solid Perfect-Surface Copper+ (PSC+) Conductors
Solid conductors prevent electrical and magnetic strand-interaction. PSC+ Solid-Copper minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation.

Carbon-Based Linearized Noise-Dissipation System (NDS)
AQ’s comprehensive Linearized Noise-Dissipation System combines multiple shields and a carbon-based linearized resistive network that turns most of this noise into heat. By “linearized,” we mean that the system is equally effective across extremely wide bandwidth, rather than at selected frequencies only, as is more common. The remaining bad energy is effectively drained away from the sensitive amplifier circuits via directionally controlled signal and shield conductors.

ZERO-Tech
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 (dielectric) and the cable’s conductors—enabling uncompressed current transfer. All-important transient current is unrestricted, and RF Noise-Dissipation is linearized (consistent octave to octave).

72v Dielectric-Bias System (DBS) with Level-X RF Noise-Trap
Insulation is also a dielectric that acts like a shunt-filter. Properly biasing the dielectric linearizes the filter, significantly improving the cable’s wide-bandwidth ability to dissipate induced noise. The DBS pack’s Level-X Noise-Trap “pulls” RF Noise out of the cable, further reducing attached audio circuit misbehavior.

Directionality
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 audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, 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.

Folk Hero Cold-Welded Terminations
Folk Hero cables are Cold-Welded to AudioQuest’s extremely pure Red Copper Spades or Bananas. The bare copper is submerged (hung) 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.

William Tell Bi-Wiring
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. With RF/ND-Tech, the advantage of Bi-Wiring is much more dramatic. Because RF/ND-Tech is so effective, BASS model cables are only for 10KHz and below; do not use a BASS cable full-range or on treble.

William Tell BASS cable is ideal with William Tell ZERO or SILVER ZERO. A Bi-Wire COMBO with BASS and ZERO cables joined together at the amplifier is usually most convenient. When Tri-Wiring, use BASS cables on the Midrange and Bass inputs.

Caution: Do not Bi-Wire with two ZERO cables. ZERO cables in-parallel can create a very high-frequency resonant peak (ringing), and resulting poor sound. Only use a ZERO plus a BASS cable (whether or not joined as a COMBO). Second best is a single ZERO with AQ Bi-Wire jumpers.

  • Solid conductors prevent strand-interaction, a major source of dynamic distortion in cables.
  • AudioQuest’s best copper. To the greatest extent presently possible, extreme-purity Perfect-Surface Copper+ (PSC+) conductors minimize distortion caused by grain boundaries.
  • ZERO-Tech eliminates the electrostatic field between the cable’s high and low signal conductors, enabling linear Radio Frequency (RF) Noise-Dissipation, and uncompressed transients.
  • 72v Dielectric-Bias System (DBS) saturates and polarizes insulation, allowing clear, dynamic sound against a quiet “black” background.
  • All conductors controlled for RF-noise directionality.
