Connecting Rythmik subwoofer to Devialet 120

[ogs]

@lal99 I am quite convinced @thumb5 is right about the stereo models. The speaker minus (black) terminals are common ground just like Linn advices. Only a bridged design (like Devialet mono-blocks) have both positive and negative active. Illustrated by the fact that speakers connect to the red binding posts on dual-mono. Devialet support should easily be able to confirm this.
