Airloc Metal 4mm Plug – Pack of 20

AIRLOC is QED's award-winning loudspeaker cable termination method that uses specialist cold weld technology. This system ensures superior contact by eliminating the resistive flaws commonly found in traditional screw or soldered terminations. The result is a highly conductive, permanent bond between the plug and cable, maintaining low resistance over the product’s lifetime. The Airloc™ method is especially beneficial when paired with QED's high-purity copper speaker cables. It removes the air between contact surfaces, which prevents oxidation and degradation of the joint, delivering consistent, high-performance audio over time. The 4mm banana plug features a new strengthened design called Forté, which adapts to both tight and loose terminal fittings, ensuring uniform insertion force and contact area. The plug is 24k gold plated to eliminate oxidization and is compatible with the full QED cable range.
