Silver Anniversary XT Bi-wire incorporates the same high performance characteristics of the award winning Silver Anniversary XT Cable.

The SA XT Bi-wire delivers a super high-end performance at a realistic price, allowing greater bass extension and control, together with more openness and detail in the mid and high frequencies. This cable continues to use the highly successful Aircore technology for efficient and effective termination

Silver Anniversary-XT Bi-Wire utilises a side-by-side ‘double figure 8’ arrangement with each silver-plated core visible through a flexible 3.9mm diameter clear polyethylene outer sheath. To ensure correct speaker ‘phasing’ the inner spacers, which maintain the cylindrical configuration of the cores, are individually colour coded. These spacers are also ‘crush-able’ to allow straightforward crimping with Airloc™ speaker plugs.

X-TUBE™ WITH AIRCORE™ TECHNOLOGY – HOW IT WORKS.

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 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.

THE SIGNAL

1.) 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.

2.) 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.

TERMINATION

We can terminate your cable with QED's superb 24 Carat gold plated AIRLOC termination plugs. AIRLOC is QED's specialised loudspeaker termination method and offers the very best termination with QED speaker cables. This is a solder-free, airtight fusion between the cable and plug and offers optimum signal transfer, excellent signal quality and perfect long-term performance.

HOW TO ORDER

Simply select the length of cable, the type of plug and the termination required (one end or both ends) from the drop-down menus above and click on the 'Buy' button to add the item to your basket. Your cable will be dispatched within 24 hours subject to Future Shop Terms & Conditions.

WHY CHOOSE QED AIRLOC FORTE

When AIRLOC Forte plugs are fitted to a cable they are subjected to such high pressure they undergo a process called 'cold welding' which transforms the plug and cable into one solid piece of metal.

The graph below shows that when full pressure is reached, resistance is at a minimum. In addition, because all the air has been removed, there will be no degradation of sonic performance caused by oxidisation of the contact area, for the whole lifetime of your cable.

NEW QED AIRLOC Forte plugs enable optimum performance and maintain signal integrity between amplifier and speaker.

QED speaker cables only use 99.999% oxygen free copper, in many cases enhanced by silver plating.

In Order to maintain channel tonal balance and minimise speaker cable resistance you should make sure your cables are of equal length.

Thanks FutureShop, very fast delivery.Quality of the airloc bannana plugs superb as well as the cable itself. Great upgrade to my previous cables.

After almost a year with this cable, I'd like to review the first comment I put as I have been able to compare this cable with cables from other brands. I found this cable extremly good at giving good music details however it also gives a very lean sound compared to competitors on the same price range. Therefore it doesn't suit all types of equipment. I have now switch to Chord which gives me full satisfaction. However, for the price Futurshop is selling this Qed Cable it still remain a good bargain.

Fantastic service and fantastic cables. Worth every penny at this price. Quality of the airloc bannana plugs superb as well as the cable itself. Great upgrade to my previous cables. Ordered on monday and recieved by 10am next day. Thanks for making it so easy and stress free buying new cables. Great company to deal with both online and in person on telephone. Will definately shop here again.

Bought this cable to go with my marrantz 6003 cd and amp and wharfedale 10.1's, Previously was using some cambridge audio bi-wire cable and have to say the improvement i have heard with this new cable is great and worth the extra cash, sonically much better and with a lot more punch. Also delivery was excellent ordered 2pm thursday with the standard postage option arrived 9-30 am friday, and it was well packaged. Very pleased
