I saw an interview video at a show where Andrew Jones is demonstrating a new Unifi speaker he designed and he says he is pleased to hear it for the first time. They used new drivers, and had designed them and the speaker on a computer then got a pair for the show from China. They never did a prototype due to time constraints. I think that was an earlier one. I can't find the video now.
I did find a video in which he said he wants the performance of his speakers to 'surprise' people.
Looks like he at least did that for many with this one.
Having seen that show video, I am not surprised there is a major resonance problem. This speaker reinforces my impression that some Elacs are great, like the new DBRs; but not all of them are great, like Revels, or good to great, like Focals.
Thanks for the review Amir.
