Something that I never have understood with ARC.
I could run Genesis 4 times with the mic positions in the same positions, and I'd get 3 or 4 different different subwoofer low extensio slope settings. It's a crapshoot of which order I get set to (1st, 2nd, 3rd, 4th).
With ARC-2, I usually got 3rd or 4th. With Genesis, it's usually 1st or 2nd, maybe 3rd.
Why the inconsistency? In other measurements like crossovers and channel levels, it's very consistent. But not in sub settings. They end to vary.
