ThunderBird BiWire Jumpers provide superior performance when biwiring is impractical, surpassing standard stamped alternatives included with most biwireable speakers. Direction-Controlled Solid Perfect-Surface Copper+ conductors are wrapped in a Conductive Carbon-loaded extrusion that suppresses RF interference for cleaner signal transmission. At 8 inches in length, these jumpers accommodate typical speaker terminal spacing while offering AudioQuest's 500-Series Hanging-Silver plated Purple Copper spades or banana connectors for secure, low-loss connections at the speaker cable interface.
