{"product_id":"qed-xt40i-speaker-cable-3m","title":"QED XT40i Speaker Cable","description":"\u003cp\u003eThe \"i\" in XT40i indicates evolution. The original XT40 was already one of the most respected speaker cables at its price point. QED took it as a starting point and added Air Gap dielectric technology, which cuts signal losses roughly in half and produces a cable that is genuinely hard to improve on without spending significantly more money.\u003c\/p\u003e\n\u003cp\u003eAir Gap works by physically separating the conductors from the jacket using a structured air gap. Air has a dielectric constant of 1.0, the theoretical minimum, so replacing solid insulation with an air-dominant structure dramatically reduces the energy stored and wasted in the insulation on every audio cycle. The 4mm cross-sectional area oxygen-free copper conductors keep DC resistance extremely low, and the low self-inductance figure means the cable does not restrict current delivery to the speaker on dynamic peaks.\u003c\/p\u003e","brand":"QED","offers":[{"title":"2.0m","offer_id":56809357508932,"sku":"QE1453","price":139.0,"currency_code":"GBP","in_stock":true},{"title":"3.0m","offer_id":56809357541700,"sku":"QE1454","price":159.0,"currency_code":"GBP","in_stock":true},{"title":"5.0m","offer_id":56823041163588,"sku":"QE1455","price":219.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/2990\/1124\/files\/QED_Cables_XT40i_3m.jpg?v=1780322520","url":"https:\/\/scratchacoustic.com\/products\/qed-xt40i-speaker-cable-3m","provider":"Scratch Acoustic","version":"1.0","type":"link"}
