QED XT40 Pre-Terminated Speaker Cable
This 3.0 meter pair of XT40 Cable is terminated with QED Airloc Banana Plugs.
This award winning pure copper speaker cable boasts QED's advanced X-Tube technology and a massive 4mm² 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 XT40, they are urging enthusiasts to audition and compare it, not only to their favourite cable but also to alternative models at any price. Prepare to be surprised!
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 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 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.
