Speakon connector

Other manufacturers make compatible products,[3] often under the name "speaker twist connector".

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).

The easiest way to remember it is to look at Neutrik part numbers where an "F" indicates Female and an "M denotes Male (eg "NL4FX" is the 'normal' cable connector (with a latch).

Speakon cables are intended solely for use in high current audio applications.

[7] The phase convention is that positive voltage on the + contact causes air to be pushed away from the speaker.
