QED's multi-award winning XT400 speaker cable, utilising X-TubeTM technology

Silver-plated oxygen-free copper tubular conductor geometry. For use in the finest hi-fi and home theatre systems. This design delivers a massive cross-sectional area using X-TubeTM technology to eliminate the skin effect whilst maintaining a user friendly "figure of 8" geometry. This is QED's ultimate affordable upgrade for high end systems.

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

At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area.

In standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor.

The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable.

X-TubeTM with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance to levels only achievable using more costly and difficult to terminate cables.

The result is more high frequency detail, less distortion and greater performance.*


*For best results we recommend termination of this cable with banana plugs. These are not included as standard. If you wish to add banana plugs on to your cable please add them to your basket seperately. Buy the cable and plugs from us and we can fit the plugs for you, free of charge! Just add your request with lengths required in the 'order notes' box when you go to your basket.
