rePhase is a
manual correction tool. You decide what to adjust, and you can decide how to smooth the data you look at prior to wiggling the sliders to make a filter to "correct" it. To some degree, it's like juggling Jello. Fix this area break that other one.
My excuse would be that when critically listening, the SPL for the low end is in the "pretty flat" area of Fletcher Munson (80-100dB), so no boost is needed.

30 minutes of "normal loud" right now. Piano, electric bass, sax, and trumpet/flugelhorn:

At lower levels, the bass is still there (enough for my ear), so no boost is needed. I don't play much louder, so no adjustment neede there, either. Music typically already has plenty of roll-off in the highs. Note the slope to -50dB starting around 1kHz, above.
I have, of course, played around with it and tend to prefer no noticeable boost in the bass for well-recorded material. I'm not a headbanger or fan of EDM, I do like to differentiate between string and electric bass and kick drum, want the 5th string of a 5-string bass (31Hz) to be 'right there", and can appreciate the lowest notes of a piano (27.5Hz) presented with appropriate weight.
As for the high end, I'm consciously immune to many of those frequencies, but folks who aren't don't complain when they sit down here and listen. If they are just judging from a distance, then I can get a response like this:
"The house curve is to put back what a normal room will do, you correct to flat which sounds rubbish and then you add in the lf room gain and the hf dropoff ." - Rodney Gold (R.I.P.)
Ok, whatever.
Here's a "corrected" in-room RTA versus the raw left and right channels of a CD. My goal at the time (and still) being "reproduce the recording" (flat response). The black traces are "live" but not well synchronized in the software, so they don't line up (some delay occurs between the three instances of REW), so I mainly pay attention to the peaks (red). Since the in-room is the sum of the L + R, the peaks won't
quite line up either, when playing stereo, but can be very close with single speaker or mono (or mono-ized) two-speaker source.
