MCM Gradient AXT-10 Woofer T/S Measurements

edited September 2017 in Hard Data
This thing measures almost spot on,(except for the Vas, which is a blessing) using WT3 added mass of 40 grams and a diameter of 8.375", I got the following.  Re 6.1,  Fs 31 Hz,  Qts .277,  Qes .212,  Qms 5.664,  Le .8486,  Mms 48.2,  Vas 3.44 cubic feet.  Has the same little wiggles in the impedance at about 900 Hz and between 2K and 3 K as the manufactures graphs.  (MCM specs differ from Gradient's document.)  A second woofer measured all most the same.  At $27.50 from MCM I took a chance and snapped up a pair.
