XT40 celebrates QED’s 40 years of award winning British heritage. Winner of ‘Best speaker cable’ at the 2018 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.
QED - Hi-Fi And Home Cinema Cables Founded by Bob Abraham and Ian Vine in 1973; QED has, over the past 40 years, acquired unparalleled knowledge and experience of hi-fi and home cinema cables and connectivity. We can also legitimately claim that, during this period, we have changed people’s perspectives about hi-fi cables. Consumers no longer believe that ‘bell wire will do’ or that ‘any old cable will be fine’. This understanding that cable quality is important and makes a real difference to your enjoyment began with the launch of the QED 79 strand speaker cable in 1978.
QED’s reputation for both innovation and technical excellence is known throughout the world. The latest computer aided design techniques allow our research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability. This is why QED speaker cables and interconnects are recommended by so many of the world’s leading manufacturers of hi-fi and home theatre equipment, and also why so many of our products have won prestigious awards.
