These speaker cables features Speakon connectors that are designed with a locking system that may be used for soldered or screw-type connections. Speakon connectors are a higher current-carrying alternative to TRS connectors, two-pole twist lock, and XLR connectors for loudspeakers. Speakon connectors lock into their sockets with a twisting motion, making them significantly less prone to disconnection than standard TRS plugs.
