At low frequencies both X-tubeTM and conventional stranded/solid core speaker cable signals in a linear way. however, at higher frequencies, X-tubeTM retains a near-linear signal transfer, whereas the conventional stranded/solid core cable fails to conduct higher frequencies uniformly across the entire conductor area.
In standard speaker cables the high frequency current density occurs at the periphery with and 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. The result induces distortion and compromises the performance of the cable.
X-tubeTM with polycore technology exhibits much lower selfi nductance and is therefore less affected by this problem. The polycore tube 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.
