    Impedance and T/S Parameters:
    • Re = 3.5805 ohms
    • Fs = 45.2438 Hz
    • Zmax = 25.9420 ohms
    • Qes = 0.5976
    • Qms = 3.7321
    • Qts = 0.5151
    • Le = 0.2889 mH (at 1 kHz)
    • Diam = 127.7620 mm ( 5.0300 in )
    • Sd =12820.1563 mm^2( 19.8713 in^2)
    • Vas = 13.8331 L ( 0.4885 ft^3)
    • BL = 5.9644 N/A
    • Mms = 20.8859 g
    • Cms = 592.4734 uM/N
    • Kms = 1687.8396 N/M
    • Rms = 1.5909 R mechanical
    • Efficiency = 0.2014 %
    • Sensitivity= 85.0595 dB @1W/1m
    • Sensitivity= 88.5510 dB @2.83Vrms/1m



    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.

    Someone tell me what this means. As in, good or bad.

      How about "there's room for improvement."

        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.

          Why is Db so insanely low compared to Dc?

            The suspension is not as good.

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