Product Description

QED Reference X Tube 400 Speaker Cable With Terminations

Note - This is a single cable, if you require a pair for your speakers, please enter quantity 2

If you wish to purchase a long length of cable please click here.

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-Tube 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-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 result is that X-Tubedelivers greater fidelity across the audio spectrum which would other wise be lost in ordinary cables.
 
Silver plated 99.999% oxygen free copper conductors

Provides a low frequency path for the audio signal and delivers stunning high frequency detail

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 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 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.

Airloc

AIRLOC is QED’s award winning loudspeaker cable termination 
method using specialist equipment.
Put simply, this is the best termination method to use with QED loudspeaker cables. The science  and engineering of loudspeaker cable doesn’t stop with the cable...
 

New strengthened plug

The new Forté plug pin section is designed to maximise contact area throughout the wide tolerance range encountered in 4mm amplifier and speaker sockets. Here, some are quite tight whereas others are loose, so the spring loaded Forté blade is designed to fit into smaller and larger sockets with equal insertion force.

This means that the contact area is maximised and the connection remains uniformly tight.

24k Gold Plated

Plugs are gold plated to eliminate oxidization, ensuring a life-long low resistance connection
