High-end speaker cable with ZERO technology and dedicated BiWire separation
Signal transfer without compromise
The AudioQuest ThunderBird ZERO BiWire COMBO is a speaker cable designed for the highest-end audio systems, where precision, control, and tonal consistency are critical. This configuration combines the ZERO cable for the mid-high range with the BASS cable for low frequencies, creating a BiWire solution optimized to maximize speaker performance.
ZERO-Tech (No Characteristic Impedance) technology eliminates the interactions between amplifier and speaker typical of traditional cables, reducing dynamic compression and distortion. Solid Perfect-Surface Copper+ (PSC+) and Perfect-Surface Silver (PSS) conductors ensure extremely clean transmission, with greater transparency, micro-detail, and three-dimensionality of the soundstage.
The result is a more controlled sound, with deep, articulate bass, natural mids, and extended yet never fatiguing high frequencies. ThunderBird ZERO BiWire COMBO is the ideal choice for reference hi-fi and high-end home theater systems.
