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.
