I just got a GK 1001rb 2 and I want to use it with my SWR Goliath cabinets. I won't be able to use the horn management system but the way I read the manual, I should be able to use a 2 conductor speaker cable with the Speakon connectors wired +1/-1 and use the woofer amp only. However, the only speakon connectors I could find locally are the NL4FC 4 pole connectors. It seems to me that these 4 pole connectors would work, they would just have 2 unused poles? Am I on the right track here or not?
