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.
Dissipation Factor@10 kHz: 0.0576
Nominal outside diameter 6.0 mm
Capacitance 59.0 pF/m
Loop Inductance 0.46 μH/m
Loop resistance 8.0 mΩ
Maximum continuous length available is 50m
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
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.
The QED XT40 is a special cable – detailed, balanced and authoritative, and we think it’s worth every penny. Go treat your system.
