{"product_id":"qed-xt40-pre-term-speaker-cable","title":"QED XT40 Pre-Term Speaker Cable","description":"Acclaimed by What HI-FI? Magazine; this 'Five Star' award winning pure copper loudspeaker cable boasts QED's advanced X-TubeTM technology and a massive 4mm2 cross sectional area. This results in a cable that delivers clear sonic advantages over conventional cable designs by maintaining a flat frequency response within the audio band.\u003cbr\u003e\u003cbr\u003e\n\nWe are so confident about the performance of the new XT40, we urge enthusiasts to audition and compare it, not only to their favourite cable but also to alternative models at any price.\u003cbr\u003e\u003cbr\u003e\n\n\nX-TUBE™ TECHNOLOGY\u003cbr\u003e\n\nAt low frequencies both X-TubeTM and conventional stranded\/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTM delivers greater detail and fidelity across the audio spectrum which would other wise be lost in ordinary cables.\u003cbr\u003e\u003cbr\u003e\n\n \n\nLARGE 4mm2 cross sectional area\u003cbr\u003e\n\nThe 4mm2 cross sectional area means XT40 exhibits very low resistance, allowing amplifiers to exert outstanding control over the speakers they are driving. In addition, its large cross sectional area makes it suitable for long cable runs.\u003cbr\u003e\u003cbr\u003e\n\n\n\n\n\n\nSpecifications\u003cbr\u003e\n1 x 24 x 10\/0.146mm 99.999% OFC closely woven braid wound round a hollow LDPE filler rod 2.8mm in diameter with a 100% coverage copper tape wrap in between; a paper wrap and pearl white finish PVC jacket comprise the cable dielectric.\u003cbr\u003e\n\nCapacitance 59.0 pF\/m, Loop Inductance 0.46 μH\/m, Loop resistance 8.0 mΩ\u003cbr\u003e\n\nDissipation Factor@10 kHz: 0.0576\u003cbr\u003e\n\nNominal outside diameter 6.0 mm\u003cbr\u003e\n\nFor best results it should be used in conjunction with QED Airloc™ Forte banana plugs. \u003cbr\u003e\u003cbr\u003e\n\n\nAt low frequencies both X-TubeTM and conventional stranded\/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area.\u003cbr\u003e\u003cbr\u003e\n\nIn standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor.\u003cbr\u003e\u003cbr\u003e\n\n\n The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable.\u003cbr\u003e\u003cbr\u003e\n","brand":"QED","offers":[{"title":"2m (pair)","offer_id":57409466171724,"sku":"QE1450","price":91.63,"currency_code":"GBP","in_stock":true},{"title":"3m (pair)","offer_id":57420980126028,"sku":"QE1452","price":108.29,"currency_code":"GBP","in_stock":true},{"title":"5m (pair)","offer_id":57420980486476,"sku":"QE1454","price":141.63,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/QED-XT40.jpg?v=1777486489","url":"https:\/\/www.stoneaudio.co.uk\/products\/qed-xt40-pre-term-speaker-cable","provider":"Stone Audio","version":"1.0","type":"link"}
