    look at the xmax figures. cmin is pretty low compared to Bl (which didn't even resolve fully).

    The suspension is not as good.

    Are the Bl and Kms graphs supposed to be on the 0 axis? Because they aren't. Also the better ScanSpeaks and other drivers that people seem to praise all seem to be closer to the 0 axis.

    Klippel 10% Distortion based Xmax:
    • X Bl @ Bl min=82% >7.7 mm *
    • X C @ C min=75% 4.0 mm


    * I pounded on this speaker (took the protection parameter on Cmin as low as I could @ 20%) and could not get Bl to resolve at all. Regardless, you're suspension limited but I still like to resolve all the parameters I can when possible.
