I guess we'll have to agree to disagree. I would only call these curves very similar where they match up. With respect, not sure how you can call a 3/4 octave 5db valley 'very similar'.
Also, as Luke Kamp points out:

It is not the 2db differences in the curve that you and others have been referencing, but approximately the 4db difference from 50 and 60hz that would sonically make the biggest difference. The 2db differences in aggregate would also have an impact to the overall sound.
Having said all that, I do believe that high quality (generally more expensive) subs will have a more pleasing sonic signature than lesser quality (cheaper) models, especially as they approach their limits. I believe that's why the JTR and Seaton examples tend to shine in these GTGs. I can't begin to tell you why they sound better with much certainty, but I would guess its because they have less distortion, better transient response, and consistent power compression compared to the other subs. These become more apparent at very high levels.
However, once you start to compare similar high quality subs, IMO the FR dominates the sound signature, and preference is highly weighted towards the preference of the listeners desired FR for the type of content playing. As the curves become more and more alike, that is when I believe the sonic signature of the subs could really be compared.
Again, IMO, FWIW, YMMV...
From what I've read so far...it sounds like you're looking for excuses to get 2 more subs!
Am I right?
With ominimic or REW, you should be able to dial in your caps nearfield so that they sound the best with movies and music. IOW, with exception to the OM, you may not have to spend 1 more penny into new subs. Just need some time to dial. Is this something that you'd think you'd want to try before you get 2 new subs?
Now...if you really want 2 additional subs then by all means get them!
