FireBird BASS Speaker Cable

FireBird BASS with RF/ND-Tech is an ideal cable for the Bass and Midrange inputs of a BiWirable or TriWireable loudspeaker when used in combination with FireBird ZERO Full-Range cable on the treble input.

FEATURES

FIREBIRD CONDUCTORS: SOLID PERFECT-SURFACE SILVER (PSS) AND SOLID PERFECT-SURFACE COPPER+ (PSC+)

Solid conductors prevent electrical strand-to-strand interaction, major sources of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the fields within a conductor, and for the magnetic fields that extend outside the conductor. The astonishingly smooth and pure surface of all AudioQuest’s Perfect-Surface metals nearly eliminates harshness and greatly increases clarity compared to lesser materials. The careful choice of the sizes of the PSS and PSC+ conductors ensures that FireBird’s performance is close to using all PSS Silver, but at a much lower cost.

RF/ND-TECH (PATENTED RADIO-FREQUENCY GROUND-NOISE DISSIPATION) MINIMIZES CIRCUIT MISBEHAVIOR BY CANCELLING INDUCED RF NOISE

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. Our unique circuit topology uses a common-mode phase-cancelling array, providing linear noise dissipation across the entire length of the cable (US Patent # 8,988,168).

ZERO-TECH (NO DEFINED CHARACTERISTIC-IMPEDANCE) FOR UNCOMPRESSED CURRENT TRANSFER AND LINEAR NOISE-DISSIPATION

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)

Insulation is also a dielectric that can act like a shunt-filter. Biasing minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced RF noise.

FIREBIRD 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. FireBird BASS cable is ideal with FireBird 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.
