Award

2014 Best Speaker Cable
"An exceptional performer and a natural upgrade from a beginner’s cable."

Recomended

"Everything about the XT40 is clear and engaging....superb performance at the price"

The Reference XT-40 boasts QED's advanced X-Tube technology and a massive 4mm 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.

QED are so confident about the performance of the new XT-40, they urge enthusiasts to audition and compare it, not only to their favourite cable but also to alternative models at any price.

This award winning cable has 1 x 24 x 10/0.146mm 99.999% OFC closely woven braid wound round a hollow LDPE filler rod 2.8mm in diameter with a 100% coverage copper tape wrap in between; a paper wrap and pearl white finish PVC jacket comprise the cable dielectric.

X-Tube Technology

X-Tube Technology

At low frequencies both X-Tube and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-Tube retains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-Tube delivers greater detail and fidelity across the audio spectrum which would other wise be lost in ordinary cables.

Large 4mm² Cross Sectional Area

Large 4mm² Cross Sectional Area

The 4mm cross sectional area means XT-40 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.
