{"product_id":"audioquest-thunderbird-biwire-jumper","title":"AudioQuest ThunderBird BiWire Jumper","description":"\u003cp\u003eThe AudioQuest ThunderBird BiWire Jumper is a ready-made speaker bridge that replaces the bundled sheet-metal strips between the terminal pairs on bi-wireable speakers. Each jumper measures about 20 centimeters and carries AudioQuest 500 series connectors on both ends.\u003c\/p\u003e\n\u003cp\u003eIt's the most unassuming component in any system — and at the same time the only one many manufacturers supply as stamped sheet metal, after spending months selecting components for the crossover right next to it.\u003c\/p\u003e\n\u003ch2\u003eWhy replace the factory bridge?\u003c\/h2\u003e\n\u003cp\u003eBecause the entire signal for the tweeter or woofer section has to pass through that piece of sheet metal, right in front of the crossover. The ThunderBird instead uses solid Perfect-Surface Copper+ — AudioQuest's high-purity, direction-controlled copper. Over that sits a conductive, carbon-loaded jacket that dissipates picked-up radio-frequency noise before it reaches the speaker. The contact ends are handled by 500 series connectors made from one-piece Purple Copper with directly applied silver.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eFour jumpers per set — two per speaker, so enough for a complete stereo pair. The ends come in four combinations: spade-to-spade, spade-to-banana, banana-to-spade, or banana-to-banana. That way you get the bridge that fits your terminal without an adapter in between.\u003c\/p\u003e\n\u003ch3\u003eWho are the ThunderBird Jumpers for — and who aren't they for?\u003c\/h3\u003e\n\u003cp\u003eFor bi-wireable speakers that already have a decent cable attached and where the last twenty centimeters shouldn't remain the weakest link. Straight talk: if your speaker has only one pair of terminals, there's nothing to bridge — then the money is better spent on the speaker cable itself. And anyone already running two complete cable pairs doesn't need jumpers either.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eOf all upgrades with a manageable effort, swapping the bridge is one of the most understandable: you replace a stamped part with a carefully chosen conductor, at a point that carries the full signal. Whether it's worth it for your speaker model, we'll tell you honestly at HD Zürisee in Wädenswil — even when the answer is sometimes no.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e bi-wire jumper (speaker bridge), ready-made\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e AudioQuest ThunderBird\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor:\u003c\/strong\u003e solid Perfect-Surface Copper+ (PSC+), direction-controlled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise dissipation:\u003c\/strong\u003e conductive, carbon-loaded jacket against RF interference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength per jumper:\u003c\/strong\u003e approx. 20 cm (8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectors:\u003c\/strong\u003e AudioQuest 500 series, one-piece Purple Copper with directly applied silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector combinations:\u003c\/strong\u003e spade–spade, spade–banana, banana–spade, banana–banana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e blue on black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e one set is enough for a pair of bi-wireable speakers (2 jumpers per speaker)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e 4 jumpers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow many jumpers does a pair of speakers need?\u003c\/h3\u003e\n\u003cp\u003eFour, so exactly one set. Every bi-wireable speaker has two terminal pairs that need bridging, on the positive and negative sides — that's two jumpers per cabinet. For speakers with three terminal pairs, i.e. tri-wiring, the requirement doubles.\u003c\/p\u003e\n\u003ch3\u003eWhich connector combination is the right one?\u003c\/h3\u003e\n\u003cp\u003eYour terminal dictates that. If the speaker cable sits with bananas in the upper terminals, there's usually room below for spade lugs — then spade-to-spade or banana-to-spade often fits. Measure or photograph your terminal, and we'll choose the right variant together before you order.\u003c\/p\u003e\n\u003ch3\u003eWhere exactly does the jumper sit in the signal path?\u003c\/h3\u003e\n\u003cp\u003eDirectly in front of the crossover, between the speaker's two terminal pairs. The entire signal for whichever section isn't directly connected runs through it. That's why the quality of this short piece matters more than its twenty-centimeter length would suggest.\u003c\/p\u003e\n\u003ch3\u003eWhy order the ThunderBird Jumpers at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we know your speaker model and its terminal, or look it up, before an order goes out — the wrong connector combination is the most common headache with jumpers.
