Banana connectors QED Airloc ABS 4mm Banana Plug (10 pcs Black / 10 pcs Red)

The QED Airloc ABS 4mm Banana Plug is a high-quality connector for speaker cable termination. It uses the patented Airloc™ cold weld technology, which fuses the conductor and plug into a solid metal joint with no air gaps — preventing oxidation and maintaining minimal resistance throughout its lifetime.

The new reinforced Forté contact design ensures a perfect fit in 4mm sockets. Its spring-loaded mechanism provides consistently tight connections and maximized contact area. The body is made of high-conductivity brass and finished with 24k gold plating to eliminate oxidation and ensure long-term low resistance.

These connectors support cables from 0.75 mm² to 5.5 mm², are compatible with the entire QED cable range, and fit 6 mm and 8 mm binding posts. Color-coded barrels (10 black and 10 red connectors included) simplify correct speaker polarity connection.
