ThunderBird ZERO BiWire COMBO combines a dedicated ZERO cable for the treble section with a BASS cable for the low-frequency section of a bi-wire loudspeaker. Its solid Perfect-Surface Copper+ conductors and separate cable geometries keep the large magnetic fields associated with bass energy away from the more delicate upper-frequency signal.
ZERO-Tech supports unrestricted transient current, while RF/ND-Tech in the bass leg helps drain radio-frequency noise away from the amplifier output. The two runs share a tidy amplifier-end connection and separate at the speaker. ThunderBird COMBO is a sensible entry into AudioQuest’s Mythical Creatures bi-wire architecture, with strong dynamic freedom and a notably quiet presentation.
