ADAM A3X Port Stuffing Ritual

Here's the results of stuffing the ports on the A3X...


The mic position may not be exactly the same, but the improvement is obvious enough.  Still it doesn't completely iron out the dip, but you can still see it is largely, of not solely responsible for it.  You lose bass output to a similar degree that you do in the A5X.

Well what can I say?  I guess all the front ported speaker faithfuls are fools.  I decided to try and block off these ports with cotton just like I did with the Behringer.  Guess what?  Same results...

I zoomed in so we could get a clear look.

No doubt about it, front ports have some serious drawbacks.

Here's what happens in the low end:

Typical stuff again--less midbass stuffed, but more of the deep bass.  Anyone want to make a prediction of how the A3X would behave under similar conditions?

Anyway, let's look at the meat and potatoes:

Polar response is great, and the vertical polar is great--large lobe aimed slightly toward the tweeter.  Just like I'd want it.

Subjectively, these are a lot like the A3X except more dynamic on the low end.  They too have zero audible vibration when doing the sweep and they actually measured absolutely identical.  Crazy stuff for me.  Never had that happen before.
