I believe that video is over a year old, so probably should not hold your breath.
In case you missed it, I posted a personal, subjective review here:

Hope you find this useful.
I too would like to see an AH review with measurements.
I did come across one measurement of their FR from sound and Vision (purple trace):
Probably the most damning thing in the FR is the hump at 1.5-2.5kHz immediately followed by the low shelf from 3-10khz. These measurements were taken about 5 months after my review, so I did not have of a FR chart when I did my review.
According to my handy pro-audio recording chart, too much 1-2kHz can sound "tinny", which is probably why I heard a metallic quality to Norah Jones voice instead of it normal breathy quality. The low shelf from 3-10kHz includes the ranges of "vocal recognition/hard consonants", "clarity and definition", and "crispness".
True these are not horrendous variations in SPL, but they are in the range that our ears are most sensitive. And when I compared them directly to the AA's with instant level-matched switching these deficiencies were obvious.
The roll-off at ~500Hz is probably why they sounded thin to my ear. The hump at around 120Hz is in the area of "Boom/Punch" per my chart and I remember being puzzled that they did have a good "hit" on a drum despite not having a "full" sound from the drum. (Good punch, but thin sound character)
To my ears the AA's are a superior speaker for a lot less $; however, if you tell us your situation - room size, function (music vs HT), budget, and purpose (surrounds, mains, etc) - we can suggest speakers for you to compare to the UniFi's.
If the UniFis are still available from Amazon, you'd have until 1/31/18 to return them, so now is a good time to perform comparisons in your home!
I bought a wall chart copy, but the chart I am referring to is here. It is interactive! Hover your mouse over frequencies of interest to get information about them:

Hope this helps!
