I don't have much faith in the built in sub eq , though I have not tried Audyssey X32. In my bedroom system I have 2 eights and I added a DSpeaker Anti mode and the difference is night and day, best 350 I spent in a long time. I measured with REW before and after and it trimmed a few peaks but it really tightened up the bass. I have a Umik-1 microphone coming and will be adding a mini dsp for my main system . As for the OP I would definitely look and see how much the ARC trimmed the bass signal going to the sub. Best to turn the sub fairly low when calibrating that way you can always make it a little hotter if you so desire.
