QED Silver Anniversary XT Bi-wire Cable 2+4 ABS AIRLOC Plugs Spades


QED Silver Anniversary XT Reference Bi-wire Speaker Cable on offer is fully terminated with a total of 6 high quality ABS Airloc Forte gold-plated banana plugs and/or ABS Airloc spades.

Please order quantity ‘2’ if you wish to order a pair of cables suitable for connecting a stereo pair of speakers.



QED Silver Anniversary XT Bi-wire Cable 2+4 ABS AIRLOC Plugs Spades

QED Silver Anniversary XT Bi-wire Cable 2+4 ABS AIRLOC Plugs Spades is terminated with 2 ABS Airloc banana plugs and/or spade terminals amplifier end and 4 ABS Airloc connectors at its speaker end.

QED Silver Anniversary XT Reference Bi-wire Speaker Cable was designed with performance in mind and the added enhancement of the Aircore™ technology found in the most prestigious QED X-Tube cables. 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 will allow your hi-fi or home cinema system to perform at its best. 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.

AIRLOC Terminated

QED AIRLOC ABS 4mm BANANA PLUGSAIRLOC Forte plugs with plastic ABS covers and improved pin section are fitted to maximise contact area throughout the wide tolerance range found in 4mm amplifier and speaker sockets. This means that the connection remains uniformly tight and with its premium gold-plating, provides optimum sonic performance through time.


QED AIRLOC ABS SPADESQED Silver Anniversary XT Reference Bi-wire Speaker Cable can also be fitted with ABS Airloc Forte spade terminals or a combination of plugs and spades.



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.

X-Tube Diagram


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.
