A locking multi-pin connector invented by Neutrik used to carry high-power speaker signals between amplifiers and passive loudspeakers, more secure than bare wire or quarter-inch connectors.
A Speakon connector is a round, locking jack invented by Neutrik in 1987 for professional audio speaker connections. It uses a twist-lock mechanism to prevent accidental disconnection and is rated to handle the high current levels required by power amplifiers driving passive loudspeakers.
Why it matters
At the power levels found in club and live sound rigs, a connection that fails mid-set is a serious problem. The locking body means a Speakon cable cannot be pulled loose by foot traffic or cable tension, unlike a quarter-inch jack which can work free silently.
In practice
Speakon connectors require a deliberate push-and-twist action to lock and unlock. If a speaker is producing distorted or intermittent sound, check that the Speakon is fully rotated into the locked position before assuming a hardware fault.
