My house curve does resemble the Harman in that it tilts up the bass at the same point. I kept the slope going to a lower frequency, which seems fine considering my relatively low playback levels. It was quite coincidental, though, as I fiddled in isolation before seeing their curve--or mine. I used BassQ, XTZ and REW to dial out the response variations, then dialed in bass EQ by ear. I know it is not correct nor perfect--but for the majority of my recordings, of all genres, it sounds right. Based on the rather stark differences among recordings, there does not seem to be universal agreement on spectral balance either, which has shifted as recording and delivery technology evolved.

I've heard plenty of music in Dolby's well calibrated theaters (they had a large part in defining the SMPTE specs), and it's not anything I'd want to live with in my home theater. Movies sound fine in those theaters, but they still sound like big PA systems in tonal character--a bit forward through the midrange, among other deficiencies. Just not my cup of tea. I don't like hearing any portion of the spectrum emphasized over any others, nor do I like any portions that appear to be recessed relative to others--in other words, I want tonal neutrality. Recessed areas are admittedly harder to detect compared with elevations--how can you tell? After you hear it, you know.
I like the sense that "everybody's in the pool" as Guy Fieri aptly puts it. I should also mention that I have found it useful to have separate Movie and Music profiles with rather less bass in the movie setting than I've been describing for music.
It could well be a case of "ignorance is bliss" for me. I have not had the pleasure of experiencing "optimally tuned" home theaters, particularly wrt bass response/level, so I don't know what I'm missing there.
