QED XT40i
The story of QED speaker cables began in 1973 with the release of the world's first specialized speaker cables, QED 42 and 79 Strand. Building on this long-standing British speaker cable heritage, QED launched a comprehensive research program into cable parameters in 1995. In 2017, "The Sound of Science," a 40-page white paper containing QED's research material since 1973, was published.
XT40i with X-Tube ™ Technology
QED's new XT40i speaker cable builds on expertise gained from nearly five decades at the forefront of cable design, replacing the renowned XT40 cable and offering another decisive step forward in sound quality.
This cable, featuring pure oxygen-free copper and QED's established X-Tube technology, ensures excellent timing and stereo imaging, and adds a brand-new and highly innovative Air Gap dielectric, bringing unprecedented rhythmic accuracy and musicality at a new affordable price.
We encourage you to try the XT40i. We are confident that you will agree with us – it even surpasses alternative cables many times its price. Prepare to be surprised and delighted.
