The QED Airloc™ ƒorté™ cold weld banana plug is a versatile termination for a wide range of speaker cables and amplifiers.
The Airloc™ ƒorté™ connector 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 ƒorté™ 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.
24k Gold Plated
The ƒorté™ plugs are gold plated to eliminate oxidization, ensuring a life-long low resistance connection.
What is Airloc™?
Airloc™ is a form of cold weld system that can be used to permanently attach QED ƒorté™ banana plugs or spade terminals 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 – 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.
Using the QED Airloc™ system, all air is removed from the joint.
There will be no oxidisation of the contact surfaces 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.
