QED Silver Anniversary cable successfully introduces QED's high end 'X-Tube' technology into a mid-priced product for the first time. The precise cylindrical construction of the silver-plated, 99.999% pure, oxygen free copper cables reduces the distortion caused by 'skin effect'. The result is a completely neutral speaker cable that allows good hi-fi and home cinema equipment to shine.
The cable is a standard 'figure 8' configuration and is attractively finished, with each silver-plated core visible through a flexible 3.9mm diameter clear polyethylene outer sheath. For ease of assembly and to ensure correct speaker 'phasing' the inner spacers, which maintain the cylindrical configuration, are each coloured coded red or white and are 'crushable' to allow straightforward crimping with 'Airloc' speaker plugs.
Silver Anniversary-XT has been specifically designed as the natural replacement for the multi-award winning Silver Anniversary speaker cable. Designed with performance in mind, the Silver Anniversary-XT speaker cable boasts all of the characteristics associated with Silver Anniversary but with the added enhancement of the Aircore™ technology found in the prestigious X-Tube series.
High performance low density polyethylene dielectric
Cuts down on the amount of audio signal energy lost due to cable capacitance.
At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cable fails to conduct uniformly across the entire conductor area. The result is that X-TubeTM delivers greater fidelity across the audio spectrum which would other wise be lost in ordinary cables.
Silver plated 99.999% OFC conductors
Provides a low frequency path for the audio signal and delivers stunning high frequency detail.

X-TUBE™ WITH AIRCORE™ TECHNOLOGY – HOW IT WORKS.
QED X-TubeOne 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 our Genesis Silver Spiral loudspeaker cables. However, this results in a product that has a very high quality sound performance, but is expensive to manufacture and can be difficult to terminate.
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. This unique tubular conductor geometry also provides lower flux density within the conductors, which gives improved transparency to the sound.
At low frequencies both X-TUBE™ and conventional stranded/solid core speaker cable convey signals in a linear way. This is represented by the uniform green colour of the strands shown in the two diagrams above.
At higher frequencies X-TUBE retains a near-linear signal transfer, whereas the conventional stranded/solid core cable fails to efficiently conduct higher frequencies uniformly across the entire conductor area. The diagram shows excess current density at the periphery (designated in red) and rapidly deteriorating current density (green through to white) 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 is induced distortion and a compromise in the performance of the cable.
X-TUBE with Aircore™ technology exhibits much lower self-inductance and is therefore less affected by this problem. The use of an innovative Polyethylene aircore enables a reduction in loop inductance to levels only usually achievable by using more costly and difficult to terminate cables.
