XT40 celebrates QED’s 40 years of award winning British heritage. Winner of ‘Best speaker cable’ at the 2014 What Hi-Fi? Awards.

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.

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.

Prepare to be surprised!

Sold in pairs and are terminated with heatshrink QED Airloc 4mm banana plugs.


At 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.

LARGE cross-sectional area

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.
