QED 8 QED Screwloc Forte Gold Plated 4mm Banana Plugs for Speakers and Amplifiers (4 Red 4 Black)

QED's reputation for innovation and technical excellence is known throughout the world. The latest computer-aided design techniques allow their research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability. This is why QED products are recommended by so many of the world’s leading hi-fi and home theatre equipment manufacturers. The new Screwloc Forte banana plug section is designed to maximise contact area throughout the wide tolerance range encountered in 4 mm amplifier and speaker sockets. Some can be quite tight whereas others may be 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. These Screwloc Forte banana plugs are made of brass which has roughly twice the resistivity of copper. For this reason the 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.
