To overcome the common problems associated with conventional speaker cable geometries – high capacitance and high inductance – QED speaker cables incorporate proprietary technologies such as QED X-Tubetm and QED Aircoretm. However, the one downside of these technological advances is the time it takes to terminate the cables. Because, to perform at their very best, they require a precise termination process.”

• XTC utilizes the same technology as Silver Anniversary X-Tube but with the removal of the silver plating and extra wide conductor   spacing it aims at a warmer and rounder sound compared to its more expensive sibling.

• HIGH PERFORMANCE LOW DENSITY POLYETHYLENE DIELECTRIC

• Cuts down on the amount of audio signal energy lost due to cable capacitance

• 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-TubeTMretains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire   conductor area. The result is that X-TubeTMdelivers greater fidelity across the audio spectrum which would otherwise be lost in   ordinary cables.

• 99.999% OXYGEN FREE COPPER CONDUCTORS

• Provides a low resistance path for the audio signal

• This unique tubular conductor geometry also provides lower flux density within the conductors, which gives improved transparency to   the sound.

Aircore™ Technology Explained

One of the big problems as cable conductor size increases, is how to keep the inductance low. This is vital to reduce cable losses and prevent inaccuracies in the signal transfer process, i.e. distortion. 
The normal way to do this is to use a number of individually insulated conductors within the cable construction. This method is utilised to great effect in the design of QED’s Genesis Silver Spiral loudspeaker cables.

To take advantage of this design ethos, but in a more conventional format, X-TUBE forms the conductor in the shape of a tube with an inner aircore. This has the same effect as using multiple insulated conductors and ensures that high frequencies are transmitted cleanly, with the added benefit of ease of termination. The unique tubular conductor geometry also provides lower flux density within the conductors, which gives improved transparency to the sound.

The overall result is more high frequency detail, less distortion and greater performance.
