I'm not suggesting to arbitrarily set everything to 80Hz. I would suggest though that if ARC has automatically selected cutoffs for the mains at or below 80Hz and at or above 80Hz for the subwoofer, adjusting them all to 80Hz can be in most cases beneficial and at least non detrimental.

Other than setting my subs to 'flat' I have found that ARC's solution is much better than setting everything to 80.
ARC does so much more-- compensating for weaknesses in all the different speakers by utilizing the strengths of other speakers-- that I think it is unwise to change the cutoff's. Period.
If you have big deficiencies in your graphs the first thing to do is us use the "quick measure" function in ARC to reposition your speakers.
If ARC sets cutoffs and cross-overs other than the old THX suggested 80 hz crossovers then it knows what it is doing.
My ears can attest to ARC's superiority over the old 80 hz crossover. Even before ARC I set my system's crossovers to 65 for fronts and 95 for subs by my ears, ignoring the recommended 80hz settings.
ARC now set's my fronts to 60hz and subs to 105/60. Guess I was on the right track.
All the additional voodoo that ARC does just makes it better.
Invest some time in positioning your speakers (again the QM function is most usefull) then TRUST ARC !!!
