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-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.

• At low frequencies both X-TubeTM and conventional stranded/solid core speaker cables convey signals in a linear way.

• 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-TubeTM 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.

• When installing structured wiring for Ethernet you want to be certain that the physical layer can accommodate the currently required network standard plus any upgrades that might be needed in the future.

• Silver Anniversary-XT has been specifically designed as the natural replacement for the multi-award winning Silver Anniversary speaker cable.

What is Airloc™?

• Airloc™ is a form of cold weld system that permanently attaches QED Forté™ banana plugs to our entire range of speaker cables.

• One of the main reasons for choosing a QED speaker cable is the superior d.c. resistance characteristics offered by our exclusive use of 99.999% oxygen free copper conductors.

• It seems a shame then to ruin all this attention to detail by neglecting the most vulnerable area of the speaker cable chain - that of the physical interface between cable and amplifier or speaker terminals.

• Seen under a microscope the surface of a typical copper strand is very rough and so using normal screw type terminals - such as found on binding posts or cheap banana plugs - electrical contact is only made in a relatively small number of places.

• Add to this a layer of oxidation - which is inevitable if copper is exposed to the air for even a short time - and the combined resistance of the cable and its termination can creep back up to levels present in a more inferior cable.

• By using a cold weld crimp type termination Airloc plugs squash the conductors and plug together to improve contact area and reduce resistance.

• As can be seen in the graph, by the time the full pressure has been applied the resistance of the joint has reached a minimum value.

• Now, because all the air has been removed from the joint there will be no oxidisation of the contact surfaces either so the low resistance will remain for the lifetime of the cable.
• During the cold weld process the cable and plug become one solid piece of metal.

• Since the copper contact has been effectively removed from the resistance equation we can concentrate on the plug to terminal resistance.

What are Forté™ Plugs?

The plugs themselves are made of solid brass which has roughly twice the resistivity of copper.

• For this reason our 4mm banana plug was devised so that its cross-sectional area would be at least double that of the cable to which it was connected effectively cancelling out the extra resistance of the plug material.

• QED then plates the connector with high purity gold which has a resistivity almost as low as copper but more importantly does not oxidise in air.

• The relatively smooth gold surfaces provide a larger contact area than the uneven copper strands in the cable and because the gold will never oxidise the contact surface remains clean and low resistance for life.

• 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 Forte 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.

• QED Forté with Airloc technology; guaranteed low resistance and strength - for life.

QED Technologies 

• 99.999% Oxygen Free Copper. Speaker cables have to carry a lot of current. If the electrical resistance of the cable is too large, part of the music signal will be lost, causing a detrimental effect on the fidelity of the sound you hear.

• To stop this from happening we make the resistance of our speaker cables as small as possible. We do this by using the largest practical cross- sectional area of copper within the size constraints of each cable.

• In order to squeeze the last drop of performance from the conductors we make sure that there are no impurities in the copper which would defeat the object of making them so large. That's why we use 99.999% oxygen free copper exclusively.

• Silver Plated 99.999% Oxygen Free Copper Speaker cables must exhibit the lowest possible resistance to the flow of electrical current.

• The larger the cross- sectional area of the conductors the smaller the resistance will be. However the cable must be small enough to be practical for its intended use.

• Although copper is a very good electrical conductor, silver is even better. By using it in our top of the range cables we can improve conductance without making the cable larger.

• As the pitch of the sound increases the current flows more and more to the outside of the conductors so we cunningly use silver plated 99.999% oxygen free copper conductors to reduce resistance only where it is needed, thus saving you money.

Low Loss Dielectric 

• Music signals in a loudspeaker cable move back and forth many times every second. The insulating material used to separate the send and return conductors from each other (the dielectric) has to be charged and discharged every time.

• Not all of the energy stored in the dielectric during each charge cycle is completely returned during each discharge cycle which has a detrimental effect on the fidelity of the sound you hear.

• That's why at QED they use low loss dielectric materials such as Polyethylene (PE) or Teflon(TM) (PTFE) in preference to cheaper PVC alternatives found in inferior unbranded cables.

AIRCORE TECHNOLOGY™

• Air Core Technology In loudspeaker cables electrical current does not flow smoothly because - rather like in a river - small eddy currents are formed.

• Eddy currents in one conductor can affect the current flowing in an adjacent conductor so that currents flowing in the same direction move away from each other.

• This "Proximity Effect" increases resistance as frequency increases which has a detrimental effect on the fidelity of the sound you hear.

• QED Aircore Technology builds on the science of X-Tube Technology and eliminates this problem by using individually insulated twisted strands arranged around a hollow core to solve both the proximity and skin effects.
