For those of you who feel that the subs lack "oomph" after ARC, both subjectively and via measurement with other tools, my experience was exactly the same for years with my 50v. I had checked it with various other measurements both with test disks and software generated test signals and there was clearly a drop in bass in the smoothed charts. It had nothing to do with the BluRay player or test disk I was using. REW most clearly demonstrated this and it kinda drove me a little crazy that it was measurably too low yet I did not really have a good way to correct for it without trying to hack the mic calibration file.
My solution then was to brute force increase the sub level by around 4 to 6 dB in the settings menu (such that it applied to all inputs equally), however this resulted in unwanted boomy boost in the cross over range. Don't increase the LFE on the remote - that will only make a difference for the LFE channel on movies, and will not take into account music or redirected bass from surrounds, etc based on the measured ARC run.
Then recently it occured to me that my ARC mic might either be faulty, or the Mic calibration file was incorrect, or I had damaged it at some point in the past. I went to Anthem and took and chance and bought a new one for around $140 (i just told them I lost the previous one so as to not get into a debate as to whether I needed a new one or not and I was out of warranty in any case and I thought it was worth a try) and voila! Problem solved. Very nice tight and strong bass, and very smooth transition between sub and speakers, and no "post ARC" adjustment required.
If yours is still under warranty, then its certainly worth a try to get a new calibrated mic. I wish I had returned mine sooner to save a few bucks and to get a better performing system sooner, but still for me it was a pretty inexpensive fix in the end.
