How many db up is the treble shelf on RTiA speakers?

Does anybody have input on how high the treble shelf is on the RTiA speakers above the crossover point to the tweeters? I've heard one person say they measure it to be 6 db hot on the treble, but that is just one data point. With EQ at -4.0 db above the 2.8 kHz crossover, they sound neutral to me, but was just wondering.

    Which model?
    I ask because: 1) I know nothing about these :p and (more to the point) 2) a quick googlage turns up Stereophile reviews (with measurements, as usual) of:
    RTi A1 (from 2008):

    My apologies if this is not helpful!
    :p

    That is very helpful! That does definitely show a peak of about 6 db, but a bit higher on the spectrum. Thanks.

    Wow. That treble hump looks a lot worse than the SL-2000 tweeter hump.

    My ears get fatigued just looking at the graph!

    Just ran YPAO correction from my receiver and the EQ curve is basically the inverse of that. Sounds better than ever now!

    Reducing the 1.5-2.5khz peak, does a lot to making them sound less forward and tiring.

    The treble is a bit hot obviously, but not the only issue.

    But oddly enough, sounds a lot better.
    I think the SL2000 issues are not all directly related to the peak they have, but other factors.

    What other issues? Not that I disagree with anything, just curious of your assessment.
