The QED Reference XT40i is a premium speaker cable designed for music lovers, hi-fi enthusiasts and demanding listeners who want a reliable connection between amplifier and loudspeakers. Within the QED range, it sits as a serious upgrade for stereo systems and home cinema installations where clarity, stereo imaging and controlled signal transfer matter. With its substantial 4 mm² conductor area, the XT40i is well suited to systems that require stable power delivery and consistent performance, including setups with longer cable runs or full-range loudspeakers.
At the heart of the QED Reference XT40i is 99.999% oxygen-free copper, combined with QED’s X-Tube™ technology and an Air Gap dielectric. This design is intended to reduce signal loss, support accurate timing and help maintain a balanced electrical behaviour across the cable. The result can be a more transparent presentation, a wider sense of space and improved rhythmic focus, depending on the rest of the system. Its extremely low DC resistance and strong electrical characteristics make it a practical choice for listeners who value detail, dynamics and natural musical flow.
The XT40i can be used with floorstanding speakers, high-quality bookshelf speakers and multi-channel systems where dependable speaker wiring is essential. It is compatible with ABS, metal and Maxi Airloc connectors, allowing a neat, durable termination for different amplifier and speaker terminals. During installation, keep polarity consistent, avoid sharp bends and consider matching left and right cable lengths for a tidy setup. Choose the QED Reference XT40i when you want a considered speaker cable upgrade that supports precision, stability and long-term listening enjoyment.
