QED Reference XT40i Speaker Cable 2 x 2m

Speaker Cable with Tube-Shaped Conductors and Banana Plugs!

For nearly 50 years, QED has been one of the world’s leading manufacturers of speaker cables. Now the company has evolved its proven XT40 into the brand-new XT40i, achieving significant improvements in sound quality.

This pure oxygen-free copper cable uses an advanced version of QED’s trusted X-Tube technology to ensure outstanding timing and stereo reproduction, adding the brand-new and highly innovative Air-Gap dielectric to deliver unprecedented rhythmic precision and musicality for a cable in this price range. The very low DC resistance boosts the already powerful audio performance of the XT40i with unmatched frequency response. The result is a cable that surpasses the standards set by its predecessor in its class.

Air-Gap Dielectric

By increasing the spacing between the conductors inside the cable and thus the amount of air between them, QED has created a low-loss air-gap dielectric. This technology halves the cable’s losses and capacitance, leading to numerous audible improvements—especially in timing and rhythmic accuracy. Despite this greater separation, the XT40i maintains the cable cross-section that makes it suitable even for long cable runs.

X-Tube Technology

Low frequencies are transmitted linearly by both X-Tube™ and conventional speaker cables. The difference appears at higher frequencies: while standard speaker cables carry most current at the outer edge of the cable, X-Tube™ technology ensures nearly linear signal transmission even at high frequencies. The audible result: more detail in the treble range, less distortion, and an overall better sound.
