Speakon connectors are rated for 40 A RMS continuous current, higher than 1/4-inch TS phone connectors, two-pole twist lock, and XLR connectors for loudspeakers. Compared to standard phone plugs, Speakon cables have many advantages. They allow for no possible confusion with low-current XLR microphone cables or 1/4" 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 and the chassis receptacles are airtight, so do not provide an air leak path from speaker enclosures.
