QED Silver Anniversary XT Speaker Cable

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.

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.
