XT40i
XT40i with X-Tube™ Technology
As befits a company rapidly closing in on its fifth decades at the forefront of speaker cable design, QED’s brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality.
This pure oxygen-free copper cable uses an evolution of QED’s established X-Tube technology to guarantee superb timing and stereo imaging, and adds the brand new and highly innovative Air Gap dielectric to bring unheard-of rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.
Air Gap dielectric
By increasing the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss Air Gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, and results in numerous audible improvements – particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, though, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs.
X-Tube technology
Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low inductance and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, that handles rhythms and tempos in the most natural and musically satisfying way, and that outperforms rival designs costing far more.
Specification
The 4 mm2 cross sectional area means XT40i 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 both short and long cable runs.
What Hi-Fi liked it so much they gave it their coveted 5 star award and remarked that ‘The Reference XT40i is very much a QED cable: you’ll struggle to get your system sounding cleaner at this price‘, before adding ‘Offers system great clarity, precision and accurate timing.’
The cable is perfect for use in a home cinema or hi-fi system where optimum performance is demanded.
The QED speaker cable story began in 1973, with the launch of the world’s first specialist speaker cables, QED 42 and 79 strand, now household names in the audio industry. Building on this longstanding British speaker cable heritage, QED embarked on an exhaustive research program into cable parameters which began in 1995 and continues into 2017 with the release of “The Sound of Science”, a 40 page White Paper distilling the research published since 1973 by QED.
These reports set out the “top down” design-principles that have resulted most recently in the development of QED XT40i loudspeaker cable – the new class leading standard in mid-range speaker cables.
