AudioQuest ThunderBird Zero BiWire Combo Speaker Cables

Building on a solid base of familiar AQ technologies, Garth and Bill specifically focused on addressing one of the most vexing issues plaguing speaker cable design: the mismatch between the amplifier’s source impedance and the speaker’s load impedance. All previous attempts to address this issue chose to move the speaker cable’s characteristic impedance to a value closer to the nominal impedance of the speakers. All such attempts failed because a speaker’s impedance changes with frequency, and the amplifier’s output impedance is something else altogether. By eliminating the ThunderBird Zero speaker cable’s characteristic impedance, current compression and distortion of the signal (current) transient is significantly reduced. The result is dynamic contrast, transient response, and bass slam that are rendered seemingly without effort.
