"The QED XT40 is a special cable – detailed, balanced and authoritative, and we think it’s worth every penny. Go treat your system."

What HiFi? Sound and Vision, October 2014

Please note this cable is not terminated and is a single length not a pair. Images are for illustration purposes only. Please enter your required length into the quantity box upon purchasing.

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 4mm2cross 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."

We 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.


At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTMretains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTMdelivers greater detail and fidelity across the audio spectrum which would other wise be lost in ordinary cables.


The 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.


  • 1 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.
  • Capacitance 59.0 pF/m, Loop Inductance 0.46 μH/m, Loop resistance 8.0 mΩ
  • Dissipation Factor@10 kHz: 0.0576
  • Nominal outside diameter 6.0 mm
  • For best results it should be used in conjunction with QED Airloc™ Forte banana plugs.
