2.1 GEO M12 and MSUB18 connections
GEO M12 and MSUB18 are connected with Speakon NL4FC plugs (not supplied). A wiring diagram is
printed on the connection panel located on the back of each cabinet. The 4 pins of the Speakon sockets
identified in / out are connected in parallel within the enclosure.
Either connector can be used to connect amplifier or to link to an additional GEO M12 cabinet or to link
to an optional MSUB18 (if present). Therefore, a single 4-conductor cable can connect two amplifier
channels to various GEO M12s and/or MSUB18 subwoofers.
