Our Bus type Universal Speaker Connector (short named: Bus Connector) is a high quality modular solder style loudspeaker cable termination system universally suited for all our loudspeaker cable and wire types. Because a connector must handle current, our design is made for this job. All parts are heavy 24 carat gold plated so oxidation is almost impossible and the contact quality is maintained over a long period of use. In short, our versatile Bus Connector provides a reliable and durable high quality connection to your amplifier and loudspeaker binding posts. For optimal contact care we recommend our The SOLUTION contact fluid.
