AudioQuest FireBird Bass Speaker Cables (pair)

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

Features

ZERO: NO CHARACTERISTIC IMPEDANCE FOR UNCOMPRESSED CURRENT TRANSFER The integrity of any audio transient (instantaneous peak-to-peak voltage swing and current) delivered from a power amplifier to a loudspeaker has always been compromised. Whether the amplifier is a valve or transistor, regardless of class of operation, the amplifier’s source impedance and loudspeaker’s load impedance are never critically matched. The speaker cable’s characteristic impedance is yet another culprit in a highly compromised non-linear electrical circuit. AudioQuest has always stated that all cables cause damage because the output is never as good as the input. However, by eliminating a speaker cable’s characteristic impedance, AQ’s ZERO Technology is an unprecedented step towards reducing that damage. The result is greater dynamic contrast, better audio transient response, and bass slams rendered seemingly without effort because the cable is not electrically restricting (strangling) the music. 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. GROUND-NOISE DISSIPATION (GND) This extremely effective patented common-mode noise-rejection technology is deployed on the ground path in almost all AQ AC Power cables, in addition to in AQ Bass & Midrange model speaker cables. The effectiveness of GND compromises audio above 10,000Hz, preventing the dedicated Bass & Midrange cable from being ideal for Full-Range use. CARBON-BASED LINEARIZED NOISE-DISSIPATION SYSTEM (NDS) 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 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. 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 an extremely wide bandwidths, rather than at selected frequencies only, as is more common. The remaining bad energy is effectively drained away from the sense amplifier circuits via directionally controlled signal and shield conductors.
