AudioQuest ThunderBird ZERO BiWire COMBO
Best high-end cable for audiophiles seeking peak performance from biwireable speakers.
The AudioQuest ThunderBird ZERO BiWire COMBO speaker cable is engineered to optimize biwireable loudspeakers by combining a ThunderBird ZERO cable for treble and a ThunderBird BASS cable for bass, conveniently joined at the amplifier end. It features Solid Perfect-Surface Copper+ (PSC+) conductors to prevent strand interaction and minimize distortion. The cable incorporates a Carbon-Based Linearized Noise-Dissipation System (NDS) and ZERO-Tech to eliminate characteristic-impedance mismatches, ensuring uncompressed current transfer. Additionally, the 72v Dielectric-Bias System (DBS) with Level-X RF Noise-Trap further enhances noise dissipation.

Know before you buy
This cable uses a dedicated ZERO cable for high frequencies and a BASS cable for low frequencies, joined at the amplifier end. This configuration prevents the interference and impedance mismatches that occur when running a single cable to a biwireable speaker, ensuring cleaner signal transfer.
The DBS creates an electrostatic field that saturates and polarizes the cable's insulation. This reduces the time-delay and smearing often caused by dielectric energy storage, resulting in a clearer, more focused sound.
Solid conductors eliminate the electrical and magnetic strand-interaction distortion inherent in stranded cables. The PSC+ copper surface is exceptionally smooth and pure, which minimizes grain-boundary distortion and provides a more refined, detailed audio signal.
The DBS system is self-contained and does not require an external power source. However, it does require a short 'break-in' period for the dielectric to fully polarize, meaning the cable will sound its best after it has been connected and used for a short time.
Yes, the ThunderBird COMBO is available with either silver-plated banana plugs or multi-spade connectors. You should choose the termination that best matches the binding posts on your specific amplifier and speakers.
This system uses layers of carbon-loaded materials to absorb radio-frequency (RF) noise before it reaches your speakers. By dissipating this induced noise, the cable prevents it from modulating the audio signal, which helps maintain a lower noise floor and better clarity.
