About The AudioQuest ThunderBird BASS Speaker Cable
ThunderBird BASS with RF/ND-Tech is an ideal cable for the Bass and Midrange inputs of a Bi-Wirable or Tri-Wireable loudspeaker when used in combination with ThunderBird ZERO Full-Range cable on the treble input.
Solid Perfect-Surface Copper+ (PSC+) Conductors: Solid conductors prevent strand-interaction, a major source of dynamic distortion. Extreme-purity PSC+ solid copper minimizes distortion caused by grain boundaries, and, when direction-controlled for surface asymmetry, facilitates crucial Radio-Frequency 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," it means 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).
RF/ND-Tech: 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 (range) of radio frequencies possible. The unique circuit topology uses a common-mode phase-cancelling array, providing linear noise dissipation across the entire length of the cable.
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 misbehaviour.
Mythical Creature Cold-Welded Terminations: Mythical Creature 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.
ThunderBird 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-Cancelling 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.
ThunderBird BASS cable is ideal with ThunderBird 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.
Our Take
The AudioQuest ThunderBird BASS Speaker Cable is a specialised solution designed to optimise bass and midrange inputs in bi-wirable or tri-wirable loudspeakers when paired with the ThunderBird ZERO Full-Range cable. Featuring Solid Perfect-Surface Copper+ (PSC+) conductors, it minimises dynamic distortion and grain-boundary interference for unparalleled signal clarity. Its Carbon-Based Linearized Noise-Dissipation System (NDS) ensures consistent noise elimination across wide bandwidths, while ZERO-Tech supports uncompressed current transfer for unimpeded transient responses. Additionally, the 72v Dielectric-Bias System (DBS) with Level-X RF Noise-Trap enhances wide-band noise dissipation. The ThunderBird BASS also employs RF/ND-Tech, a patented RF-cancelling system, making it ideal for frequencies below 10kHz, and it excels in bi-wiring configurations for improved performance and reduced distortion.
