The QED Airloc QE1910 Banana Plug (Each) is QED’s award-winning loudspeaker cable termination method, which uses specialist equipment.
Put simply, this is the best termination method to use with QED loudspeaker cables. The science and engineering of loudspeaker cable doesn’t stop with the cable.
New strengthened plug
The new QE1910 Banana Fortรฉ plug pin section maximises contact area throughout the wide tolerance range encountered in 4mm amplifier and speaker sockets. Some are tight, whereas others are loose, so the spring-loaded Fortรฉ blade fits into smaller and larger sockets with equal insertion force.
This means maximum contact area and the connection remains uniformly tight.
24k Gold Plated
Plugs use gold-plating to eliminate oxidization, ensuring a life-long, low-resistance connection.
What Is Airloc
Airloc is a cold weld system that permanently attaches QED Fortรฉ banana plugs or spade terminals to our overall 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.
The surface of a typical copper strand is very rough when seen under a microscope. Using normal screw-type terminalsโas found on binding posts or cheap banana plugsโonly a relatively small number of places make electrical contact.
In addition, 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 a cold weld crimp type termination, Airloc QE1910 plugs, squash the conductors and plug together to improve the contact area and reduce resistance.
Because all the air has been removed from the joint, the contact surfaces will not oxidise, so the low resistance will remain for the cable’s lifetime. During the cold weld process, the cable and plug become one solid piece of metal.
