QED Reference XT40 Speaker Cable - Terminated

"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

Professionally terminated in house with terminations of your choice. Image below shows QED Metal Airloc Banana Plugs. All QED plugs used are Official QED Airloc terminations.

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.

There is far too much nonsense talked about cables this is fine product and conducts electricity within the appropriate frequency band perfectly well as does most wire! well made but still pricy but not compared to some silly stuff.

QED XT40 Speaker Cable
Friday, 10 July 2015  | 

A superb sounding speaker cable from QED. Even fresh out of the package without any burn in time the cable sounds open, highly detailed and very emotionally involving. Highs and lows are conveyed accurately without any sense of shrillness at the top end or boominess at the bottom end. A wonderful addition to my system.

My set-up is as follow:
Rega Elicit R
Rega RP1(white belt, Denon DL-110)
PatheWings mat
Magneplanar MG12 speakers
The QED XT40 really brought the sound to a new level, bass is tight, soundstage improved and vocals natural, all that without breaking the bank!
