The screwloc forte 4mm Banana Plug is the ideal finishing connection to ensure you get the best from your speaker cable.
Designed for use where speed and convenience are the paramount concern, these connectors make the most of the Screwloc style termination providing a twin conductor clamp to suit cable diameters up to 3.25mm. The new forte plugs are 24k Gold Plated which has a resistivity almost as low as copper but more importantly does not oxidise in air.
The new Forte plug section is designed to maximise contact area throughout the wide tolerance range encountered in 4mm 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.
The plugs themselves are made of brass which has roughly twice the resistivity of copper. For this reason the 4mm banana 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.
