I really wasn't expecting an answer although I might rely more on speaker graphs if they could tell me what a speaker would ultimately sound like (I'm not talking about the ones with extreme peaks and such). If I could look at perfectly flat graphs and then be able to identify the speaker that would sound veiled, thick, lush, boxy, full of re-verb, etc. that would be great because I could exclude them from my auditions - but I can't so listening takes precedence. Another thing to consider is who did the measurements, in what room and with what equipment, etc. Even a guy like John Atkinson has bad days

. Too many variables IMO. I trust my ears to tell me what transducers I like.
My point was that I don't think a graph plot-line tells the whole story when it comes to speakers. It would be a shame not to audition and possible enjoy a fantastic speaker line like the Diamonds just because a graph says they're not perfect or ideal.
I've listened to speakers with nearly identical graphs that sounded well... like different speakers. My point is that when it comes to speakers I put more stock into listening as opposed to reading graphs. I feel differently about graphs and specs when it comes to amplifiers but that's another story.
I still don't think a "tonal aberration", if measured, would sound the same on two different speakers. Anyway, what I'm describing is not forwardness or presence, it's actually the lack of sound if that makes sense. The air and space that these speakers provide really do remove that "pane of glass". You can actually "look" deep into a recording. If that's an "aberration...I want more of it.
As they say, beauty is in the eye of the beholder.
