Done right, BiWiring enables better sound for less money. However, for various reasons, there are times when BiWiring may not be possible. For those times, AudioQuest BiWire Jumpers deliver significantly improved performance over the common stamped jumpers that are included with most BiWireable loudspeakers. ThunderBird BiWire Jumpers employ Direction-Controlled Solid Perfect-Surface Copper+ (PSC+) covered with a Conductive Carbon-loaded extrusion that reduces RF pick-up. ThunderBird BiWire Jumpers are 8” long and available with AudioQuest’s 500-Series Hanging-Silver plated Purple Copper spades or bananas on either end — simplifying the connection where the speaker cable is attached.
