No possible confusion with low-current microphone or instrument cables. They lock into their sockets with a twisting motion, making them significantly less prone to disconnection than standard phone plugs. They are shielded from human touch, preventing electrical shock from a high-powered amplifier. The contacts do not short out during connection or disconnection. This can be a benefit when working with sound equipment that is in operation. The chassis receptacles are airtight, so do not provide an air leak path from speaker enclosures.


A Speakon connector is designed with a locking system that may be designed for soldered or screw-type connections. Line connectors (female) mate with (male) panel connectors and typically a cable will have identical connectors at both ends. If it is needed to join cables, a coupler can be used (which essentially consists of two panel connectors mounted on the ends of a plastic tube). Recently the manufacturer has introduced a new series called STX which includes also male line connectors and female panel connectors (in the four-pole and eight-pole version only).
