Xangsane's XS-6001AU LONG speaker terminals are ideal for mounting on enclosures and/or loudspeakers with wall thicknesses from 2mm to 18mm maximum. They feature non-slip seals. Connector contacts are made of gold-plated pure copper for enhanced conductivity and resistance to corrosion and oxidation. The internal cable is mounted without soldering, using a hexagon socket screw. On the other side, these connectors accept forks and banana plugs.
