Aura 3"...phase plug?

Looks good!

If you fold a piece of sellotape into a diamond shape with the glue on the outside, you can run it around the VC gap and get the last few bits of stuff out.

If there is anything in there, and it doesn't work its way out, then i'll give that a try... the VC is awefully deep thou, may be real tricky.

that last head on pic is damn sexy imho

measured (i didn't take a baseline for the slice & dice driver)

Driver              Fs        Qms     Qes      Qts 
#1 no dust cap     96.74    7.286    0.766    0.693
#1 no phase plug   96.64    7.070    0.763    0.689
#2 stock          103.29    7.553    0.902    0.806
#3 stock           98.63    7.887    0.864    0.779
#4 stock           98.94    8.187    0.870    0.786

with no reference we can only note that the modded driver has a lower Fs than the other 3 (i would expect it to rise due to lower mass), and the Qts is lower.

And the impedance curves. They pretty much fall on top of each other...

Red is #1, no cap, yellow dashed with the dust cap, the other 3 drivers in darker colors. Note the small glitch at just above 500 Hz & larger one just below 3 khz. These are absent in the stock drivers.

And a couple pictures with the phase plug that i made to fit...
