Neutrik speakON 4-Pole Lockable Adapter NL4MMX Male-Male Coupler for Linking NL2/NL4 Cable Connectors
Extend the run. Lock it down.
The NL4MMX is a lockable 4-pole speakON adapter that links two NL2/4F cable connectors to extend a speaker cable, or locks onto a cable end to change it to male.

Speaker cable ends that will not mate
Two female cable connectors cannot join on their own. A cable that needs a male end or more length stops the setup until you have the right adapter.
