Each speaker has to be normally connected (r ed and ora nge wires on red terminals) but a polarity invertion on the speaker 2 is required. This invertion is being made at the factory, directly on the LS connection plate. Check that when excited threw the SPEAKON with a DC battery, both loudspeakers are moving towards you.
