  • Dayton AMT Mini 8 - how was it mounted when measured for the spec sheet?

    I wonder if it was flush mounted - if it wasn't, perhaps that would account for the lack of smooth response shown in the .PDF file?

    I suppose I'll add one to my next order, don't know if that will be soon - but I really would like to see some independent measurements, I bet they might look better

      That suckout at ~6300 does look suspiciously like it was surface mounted. I had a similar suckout, slightly higher in frequency, when I surface mounted a car audio dome tweeter.
      Don't listen to me - I have not sold any $150,000 speakers.

        How did they get T/S measurements? I tried to use DATS, but this gives me Re of 6.8945, FS of 9072, QTS of 0.55....useless. Doesn't match the spec sheets at all

          How does a speaker with no impedance peak have an Fs? Dats needs to see the bump in the impedance to do it's thing. Since there isn't one, it can't. I wouldn't worry about it, the impedance is flat so what do you care what Fs is? Re = Z across the entire frequency spectrum ,and Qts is useless for anything being used as a tweeter.
