Linking Speakon Speaker Cables Requires A Special Coupler
Since Speakon speaker cables are equipped with the same connector on both ends, a special adapter is required to connect two or more cables to make a longer cable.
An adapter called a “Speakon coupler” is used to create a locking connection that couples two cables with identical connectors together.
The Speakon connector is inserted into the adapter and turned one quarter turn clockwise to lock. Multiple couplers can be used to create long cable runs.
