X-TUBE™ TECHNOLOGY

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

LARGE CROSS-SECTIONAL AREA

The 4mm² cross sectional area means XT40 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.

At low frequencies both X-Tube^TM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-Tube^TMretains 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-Tube^TM 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.
